Backed by 4,800+ GitHub stars and trusted by teams replacing LaunchDarkly and Split with a self-hosted solution, Flipt v2 delivers the first truly Git-native feature management platform that treats feature flags as code stored in your own repositories. The architecture eliminates all database dependencies by building immutable in-memory snapshots from YAML flag definitions on every Git commit, delivering sub-millisecond evaluation latency with zero external runtime dependencies beyond the single Go binary. Multi-environment support maps directly to Git abstractions — separate repositories per environment, different directories within the same repository, or different branches — enabling teams to use their existing branching strategy, pull request workflows, and code review processes for flag changes. The evaluation engine supports boolean flags, multivariate string and numeric variants, segment-based targeting with constraint rules, percentage rollouts, and namespace isolation. Native SCM integration with GitHub, GitLab, BitBucket, Azure DevOps, and Gitea creates merge proposals directly from the UI with GPG-signed commits. Flipt implements the OpenFeature Remote Evaluation Protocol with official providers for Go, Node.js, Python, Java, C#, Ruby, and Web SDKs, enabling vendor-agnostic flag evaluation across all services. The gRPC API with REST HTTP gateway exposes flag management, evaluation, and analytics endpoints. Offline mode continues serving flags when the source repository is temporarily unavailable. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Fair Core License (server) / MIT (client SDKs).

Page views, referrers, browsers, and screen sizes - Ackee delivers the analytics developers actually check, from a deliberately minimal Node.js and MongoDB stack that skips both Matomo's weight and Google Analytics' cloud dependency. Its defining constraint is anonymization: no cookies, no unique user tracking, and a multi-step anonymization process that keeps visitors unidentifiable while the aggregate numbers stay useful. In its default anonymous mode Ackee collects no personally identifiable information at all, which means GDPR and CCPA compliance out of the box and no cookie consent banner on your sites. A detailed mode adds screen size, language, and per-visit referrers - still without cookies or fingerprinting. Integration mirrors the Google Analytics pattern: create a domain in settings, drop the generated ackee-tracker snippet into your pages, and data appears in a clean single-page dashboard. One instance tracks multiple domains, and custom events capture button clicks, signups, and conversions. The distinctive engineering choice is the fully documented GraphQL API: everything the dashboard shows comes from that API, so you can query active visitors, average duration, and view statistics programmatically, feed data in from apps and services beyond websites, or build an entirely custom interface on top. If you want bare-minimum analytics with a real API and zero privacy anxiety, this is the tool.

Cerbos decouples authorization logic from application code entirely, evaluating human-readable YAML policies in under one millisecond through a stateless Policy Decision Point that requires no application state synchronization or cross-network fan-out. Its custom decision engine benchmarks up to 17x faster than OPA-based alternatives. Access control policies use conditions expressed in Google's Common Expression Language, supporting role-based, attribute-based, and policy-based access control patterns including derived roles, scoped policies, and permissions-aware data filtering that pushes authorization predicates directly into database queries. The PDP exposes both gRPC and HTTP APIs with SDKs for JavaScript, Python, Go, Java, .NET, Rust, PHP, and Ruby, making integration a single function call regardless of tech stack. GitOps-native workflows treat policies as code with Git versioning, CI validation through GitHub Actions, coverage reports, breaking-change detection, and audit logs of every authorization decision for ISO27001, SOC2, and HIPAA compliance. Deployment flexibility spans Kubernetes sidecars, standalone services, systemd daemons, AWS Lambda functions, and WebAssembly-embedded PDPs that run authorization logic directly in browsers, serverless architectures, and edge devices. The Admin API manages policy lifecycle operations programmatically, while the built-in Playground and REPL provide interactive testing environments for policy authoring and debugging. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache 2.0 licensed.

Agenta delivers a comprehensive open-source LLMOps workspace that covers the full lifecycle of AI application development — from prompt engineering through production monitoring. The platform supports 15+ model providers including OpenAI, Anthropic, Google Gemini, Mistral, Groq, Together AI, Azure, AWS Bedrock, and self-hosted models via Ollama, enabling teams to switch between providers without code changes. The prompt playground allows side-by-side comparison of different configurations, while the evaluation system offers LLM-as-a-Judge assessment, 20+ pre-built evaluators covering semantic similarity, regex matching, and factual accuracy, plus custom Python evaluators for domain-specific requirements. Teams run evaluations through both the web UI for subject matter experts and the Evaluation SDK for programmatic CI/CD integration. The observability layer captures full trace visibility across complex agentic workflows, flagging quality issues like hallucinations and off-topic responses in real time. Human annotation workflows let domain experts review and annotate LLM outputs, feeding corrections back into the evaluation loop. The architecture supports Chain of Prompts, RAG pipelines, and multi-step agent workflows, integrating with frameworks like LangChain and LlamaIndex. Self-hosting deploys via Docker Compose with Traefik for routing, requiring only a clone, environment configuration, and a single docker compose command. On RepoCloud, deploy Agenta on a dedicated VPS with root SSH access, persistent storage for evaluation datasets and traces, and complete control over model provider credentials, all under the MIT license with no usage restrictions.

Backed by the Linux Foundation with contributions from AWS, Cisco, IBM, Microsoft, Red Hat, and Shell, Agentgateway is the first data plane built from the ground up for AI agent workloads — providing a unified Rust-based proxy that handles conventional HTTP and gRPC traffic alongside MCP tool servers, A2A agent communication, and LLM inference endpoints through a single deployment. The LLM gateway routes requests to OpenAI, Anthropic, Gemini, AWS Bedrock, and other providers through an OpenAI-compatible unified API with per-tenant budget controls, spend tracking, prompt enrichment, load balancing across multiple model endpoints, and automatic failover when providers experience outages. The MCP gateway federates multiple tool servers behind one endpoint, supporting stdio, HTTP/SSE, and Streamable HTTP transports with built-in OAuth authentication compliant with the MCP auth specification, integrating Auth0 and Keycloak out of the box. OpenAPI integration exposes existing REST APIs as MCP-native tools without code changes, enabling legacy services to participate in agent workflows. Policy-based RBAC controls which agents access which tools, while OpenTelemetry integration provides distributed tracing across agent communication chains. Deploy as a standalone binary with flat YAML configuration or on Kubernetes using the built-in controller with Gateway API support for declarative infrastructure-as-code management. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache 2.0 licensed.

Unlimited agents, unlimited tickets, unlimited mailboxes, forever, on a $4 VPS - FreeScout's pricing inversion is why it became the most popular self-hosted Help Scout alternative, a PHP/Laravel help desk and shared inbox developed from scratch over eight years. The inbox deliberately behaves like Gmail or Outlook, so new support agents need close to zero training. The email-support core is genuinely complete: seamless IMAP/SMTP integration including modern Microsoft Exchange authentication, collision detection that warns when two agents open the same conversation, canned responses, auto-replies, internal notes, open tracking, starring, forwarding, merging, and moving conversations between mailboxes, phone-call logging, push notifications, and an auto-refreshing conversation list - plus screenshot pasting straight from the clipboard into replies. It's 100% mobile-friendly, fully screen-reader accessible, and translated into 28 languages. Beyond the core, an ecosystem of 100+ modules (mostly one-time $12-20 purchases) adds knowledge base, workflows with Gmail-filter-style automation rules, satisfaction ratings, time tracking, tags, custom fields, LDAP, Slack, WhatsApp and Telegram channels, and an API with webhooks - pay only for what your team needs. Web installer and updater included. AGPL-licensed.

What Gmail did for email, Octobox does for GitHub notifications: an ephemeral, unmanageable stream becomes an inbox you can actually triage. GitHub marks notifications read the moment you glance at them and lets old ones vanish days later; heavy maintainers end up building elaborate Gmail filter systems just to cope. Octobox - a Ruby on Rails app over PostgreSQL - syncs your notifications into a persistent inbox with an explicit archived state: mark a thread done, and if the issue or PR sees new activity, it pops back automatically, so nothing silently falls through. Triage is keyboard-driven with Gmail-style shortcuts (j/k to navigate, e to archive, m to mute, s to star), and multi-select clears noisy repositories in bulk. Filtering is where it earns its keep: slice by repository, organization, type, action, state, reason, CI status, labels, author, assignee, or bot origin, combine prefix search filters, and pin favorite searches to the sidebar. The optional GitHub App enriches entries with live PR/CI status and labels so you can decide without clicking through. Auto-archive rules clear merged PRs and closed issues; muting and snoozing silence the rest. A REST API supports integrations. Self-hosting keeps your notification metadata - a map of everything you work on - on your own server.

Its author, a student and WakaTime fan, didn't want to pay $9/month for data about his own keystrokes - so Wakapi was born, a self-hosted, WakaTime-compatible backend for coding statistics. The compatibility is the killer design decision: the official WakaTime plugins for VS Code, JetBrains IDEs, Vim, and dozens of other editors work unmodified - just point the plugin's API URL at your Wakapi instance with your personal key, and heartbeats flow to your server instead of a third party's. Duration inference matches WakaTime's own algorithm, with a configurable timeout (10 minutes by default). From that stream Wakapi builds statistics and plots across projects, languages, editors, hosts, and operating systems, plus the fun extras: public leaderboards (optionally login-gated, with configurable aggregation windows), badges for GitHub readmes, and weekly email reports. A REST API serves your data programmatically, Prometheus export feeds your existing Grafana, and a WakaTime relay mode can mirror heartbeats to both services during migration - with one-click import of historical WakaTime data. Written in Go, it is lightning fast and light enough for the smallest instance, storing to SQLite, PostgreSQL, or MySQL, with configurable data retention for GDPR peace of mind. Deliberately smaller than WakaTime, deliberately yours.

Every Redis client you already use connects to Kvrocks without a single code change, but instead of holding your entire dataset in RAM, data lives on SSD through RocksDB, turning terabytes of memory cost into pennies of disk. An Apache Software Foundation top-level project, Kvrocks supports strings, hashes, lists, sets, sorted sets, streams, bitmaps, JSON documents, TimeSeries data points, Bloom filters, Cuckoo filters, and HyperLogLog structures, all persisted to disk with in-memory caching for hot data access. Asynchronous replication using binlog similar to MySQL provides data durability across replicas, while Redis Sentinel integration enables automatic failover when master or replica nodes fail. The proxyless centralized cluster architecture distributes data across shards while remaining fully compatible with standard Redis cluster SDKs and clients. Token-based namespaces provide multi-tenant isolation with authentication per namespace, going beyond Redis SELECT's numbered database model. RocksDB's LSM-tree storage engine provides efficient compression through configurable compaction strategies, reducing disk footprint dramatically while maintaining sub-millisecond reads for cached keys. Migration tooling includes RedisShake for Redis-to-Kvrocks live migration and kvrocks2redis for reverse migration, enabling gradual adoption without service interruption. The kvrocks_exporter exposes Prometheus-compatible metrics for monitoring, and OpenTelemetry integration provides distributed tracing. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache 2.0 licensed.

With 4,300+ GitHub stars and native mobile apps on three platforms, Black Candy transforms any VPS into a private Spotify-style streaming service for your personal music collection. The Ruby on Rails 7 backend with Hotwire Turbo and Stimulus delivers a responsive single-page-feeling web player supporting album browsing, artist views, playlists, favorites, and queue management without full page reloads. Point it at a media directory containing MP3, FLAC, OGG, AAC, or WAV files and Black Candy indexes metadata, fetches album artwork from Discogs API, and begins streaming immediately with on-the-fly transcoding that adapts bitrate to client bandwidth. Multi-user support gives each account independent playlists, favorites, and listening history while sharing the same music library — ideal for families or shared households. Native iOS, Android, and F-Droid apps maintained as separate repositories provide offline caching, background playback, and server discovery for mobile listening. The admin panel manages user accounts, configures media paths, and sets Discogs API tokens for automatic cover art retrieval. Deployment requires one Docker command — `docker run -p 80:80 ghcr.io/blackcandy-org/blackcandy:latest` — with persistent storage volumes for the SQLite database and media directory. For larger deployments, switch to PostgreSQL via environment variables with dedicated database URLs for ActionCable, SolidQueue, and SolidCache. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

With over 4,300 GitHub stars and a v3 release adding built-in user management, team views, and multi-language support, Kubero has established itself as the most feature-complete open-source Heroku alternative running natively on Kubernetes. The platform operates as a Kubernetes operator with two containers — kubero-ui and the operator — storing all state in etcd without an external database. Developers push code via Git integration with GitHub, GitLab, Bitea, or Gitea, and Kubero automatically builds using Buildpacks, Nixpacks, Runpacks, or Dockerfiles, then deploys to the configured domain with SSL via cert-manager. CI/CD pipelines support up to four staging environments — review, test, staging, and production — with per-stage environment variable isolation and ephemeral review apps that spin up on pull request open and tear down on close. The template catalog includes over 170 pre-configured applications like WordPress, Grafana, and PostgreSQL deployable in one click, while managed add-ons provide highly available PostgreSQL, Redis, MySQL, Kafka, CouchDB, Elasticsearch, and MongoDB alongside your applications. Security features include Trivy vulnerability scanning, GitHub and OAuth2 single sign-on, basic auth, and a role-based permission system with API tokens. The NestJS backend with Vue.js and Vuetify frontend provides application metrics, real-time logs, a built-in web console for container access, scheduled cronjob management, and deployment notifications via Discord, Slack, or webhooks. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Flexprice is a developer-first billing platform built specifically for AI-native and SaaS companies that need usage-based, credit-based, and hybrid pricing models without building custom billing infrastructure. The metering engine ingests millions of usage events in real time through HTTP APIs or SDK calls, supporting sum, count, unique count, latest value, and multiplier aggregation strategies across custom event schemas like API calls, token counts, compute minutes, and GPU time. Credit management handles prepaid wallets with promotional grants, rollover caps, auto top-ups, and priority-based credit application during invoice generation. The pricing engine supports per-unit, tiered, volume, package, and flat-rate models with per-customer overrides, committed minimums, and enterprise contract terms. Feature entitlements enforce boolean toggles, metered usage limits, and configuration values per plan, enabling applications to gate functionality through simple API checks. Automated invoicing calculates charges from real-time usage data with proration for mid-cycle upgrades and downgrades, generating detailed line items linked to tracked consumption. The architecture separates event ingestion through Kafka from billing computation via Temporal workflow orchestration, allowing each layer to scale independently with ClickHouse handling high-performance usage aggregation. Stripe Connect integration processes payments and manages customer payment methods. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPLv3 licensed.

Ever Gauzy consolidates ERP invoicing, CRM sales pipelines, HRM employee records, applicant tracking, and project management into one full-stack TypeScript platform, eliminating the need to stitch together five separate SaaS subscriptions. Over 4,300 GitHub stars and 3,800+ releases back a CQRS architecture that separates command and query responsibilities across modules for invoices, expenses, payments, inventory, contacts, leads, deals, employee onboarding, candidate interviews, hiring workflows, sprints, goals, and KPI tracking. Time tracking captures hours via web timer, Electron desktop timer with activity monitoring and automatic screenshot capture, or browser extension, with timesheet submission and approval workflows supporting billable hour classification across Hubstaff and Upwork integrations. The multi-tenant architecture provides automatic tenant scoping with role-based permissions, while dual ORM support through TypeORM and MikroORM with Knex query builder ensures database flexibility across PostgreSQL, MySQL, and MariaDB. REST APIs documented with OpenAPI and Swagger expose every module for headless operation, complemented by an MCP server offering 323 tools for AI assistant integration. The Angular 19 dashboard provides dark, light, corporate, and material themes with i18n across 10 languages via Crowdin. Supports Docker, Kubernetes, Terraform, and Pulumi deployment with Redis caching and OpenSearch full-text indexing. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Service businesses get a booking page without per-booking commissions or monthly SaaS fees from Easy!Appointments, the self-hosted appointment scheduler. Customers pick a service, provider, and open time slot from a clean web form; the system enforces working plans, breaks, and booking rules you define per provider, then confirms by email to both sides. The structure fits real service organizations: multiple providers with individual schedules, multiple service types with their own durations and prices, and admin/secretary roles for front-desk management. Two-way Google Calendar synchronization keeps each provider's external calendar authoritative - book in Easy!Appointments and it appears in Google Calendar, block time in Google and the slot disappears from the booking form. Version 1.6 adds SMS notifications and payment support, and a REST API opens the scheduling data to custom integrations. Built on PHP (CodeIgniter) with MySQL, it installs in a single folder and can share a database with your existing site; a WordPress plugin embeds the booking form directly in pages or posts. The interface ships in dozens of languages with time-zone handling throughout. GPL-3.0 licensed and free for commercial use - a helpdesk, clinic, salon, or consultancy runs its whole booking workflow on its own server.

Backed by Y Combinator with 4,300 GitHub stars and growing rapidly since its September 2024 launch, Briefer delivers the first truly unified notebook-and-dashboard platform that eliminates the fragmented workflow of juggling Jupyter for analysis, Tableau for visualization, and Notion for documentation — combining all three in a single Notion-like workspace where SQL query results automatically become Python DataFrames accessible in subsequent code blocks. The built-in AI analyst understands your database schema and notebook context to generate SQL queries, write Python transformations, create visualizations, and fix errors on demand using configurable OpenAI or private LLM backends. Connect directly to PostgreSQL, MySQL, BigQuery, Redshift, Snowflake, and Amazon Athena as data sources, or upload CSV files for immediate analysis. Native point-and-click visualizations produce charts, tables, and dashboards without writing code, while interactive data apps use inputs, dropdowns, and date pickers to create parameterized reports for non-technical stakeholders. Scheduled execution runs notebooks and dashboards periodically with results delivered via Slack integration or public shareable links. Write-back queries modify production data directly from notebooks for ad-hoc pipeline testing. The architecture runs as three Docker containers — web frontend, API server, and optional AI service — backed by PostgreSQL and a Jupyter server for Python execution, deployable via single Docker command, Docker Compose, or Helm charts for Kubernetes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPLv3 licensed.

Subtitles are the one chore Sonarr and Radarr leave behind - Bazarr finishes the *arr media stack by automating them. It connects to both via their APIs and mirrors their libraries - it doesn't scan disk itself, it manages exactly what your *arr apps index. For every monitored episode and movie it checks existing internal and external subtitles against your language profiles, then hunts missing ones across dozens of providers - OpenSubtitles.com, Podnapisi, Addic7ed, Subscene, and many regional sources - covering 184 subtitle languages including forced/foreign-dialogue tracks. Matching is smarter than filename guessing: releases are compared by release group and source, some providers support exact file-hash matching, and every downloaded subtitle gets a percentage score. Set a minimum score per Sonarr/Radarr connection and Bazarr rejects weak matches; enable upgrades and it replaces previously downloaded subtitles when better ones surface. Out-of-sync files get fixed too - automatic subtitle synchronization realigns timing after download, triggered only below a configurable score threshold so good subs aren't touched. Per-show and per-movie language configuration, download history, manual on-demand search, and adaptive searching that throttles provider API calls round it out, all behind a clean Sonarr-style web UI written in Python. If your library serves multilingual viewers, this removes the last manual step.

Archestra delivers the enterprise AI infrastructure layer that organizations need when managing multiple LLM providers, MCP servers, and AI agents across teams becomes unmanageable. The LLM gateway routes requests across Anthropic, OpenAI, Azure, Bedrock, and DeepSeek with virtual API keys, per-team cost limits, and dynamic model routing — giving every developer one token for Claude Code, Cursor, or Codex while finance tracks spend per department. The MCP gateway authenticates tool calls with OAuth 2.1 and On-Behalf-Of tokens so each tool executes as the calling user, not a shared service account, eliminating credential sprawl. The private MCP registry lets teams publish custom tool servers with approval flows promoting servers from dev through staging to production, each environment maintaining its own credentials and network egress policies. The Kubernetes operator manages MCP server lifecycle — deploying containers, scaling, health-checking, and routing gateway traffic to local servers automatically. The agent runtime supports scheduled triggers, email and webhook invocations, sub-agent delegation, reusable skills, and sandboxed code execution with a K8s-native filesystem. Deterministic guardrails including Dual-LLM verification and Lethal Trifecta protections prevent dangerous tool calls before execution. Built-in OpenTelemetry traces and Prometheus metrics provide full observability without additional tooling. Docker deployment exposes the Admin UI on port 3000 and API on port 9000 with a single command. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

2FAuth generates TOTP, HOTP, and Steam Guard codes from any web browser, freeing your two-factor authentication from dependence on a single smartphone or app. Lose your phone, switch devices, or sit at a desktop computer, and your 2FA codes remain accessible through the web interface. The Laravel and Vue.js application stores account secrets in an encrypted SQLite database that backs up as a single file. Adding accounts works through camera-based QR scanning or manual secret key entry for services that only provide text codes. Group organization with drag-and-drop sorting keeps large collections navigable, categorized however you prefer. WebAuthn authentication with FIDO2 hardware keys protects vault access with phishing-resistant passwordless login, meaning the tool that secures your accounts is itself secured by the strongest available method. Automatic screen lock triggers after configurable idle time, and OTP obfuscation dots out generated codes until you tap to reveal them, preventing shoulder surfing in shared spaces. The REST API enables browser extensions and external applications to request codes programmatically. Import compatibility with Google Authenticator, Aegis, and 2FAS ensures painless migration without re-enrolling every account from scratch. PWA installation places 2FAuth on your device home screen for native-app-like instant access. Runs on a dedicated RepoCloud VPS with guaranteed resources and full root SSH access. AGPL-3.0 licensed.
