Created by Uber Technologies and graduated as the seventh CNCF top-level project in October 2019 with over 23,000 GitHub stars, Jaeger has become one of the most widely deployed open-source distributed tracing platforms, processing billions of spans per day in production environments at organizations including Uber, Red Hat, and Shopify. Version 2 rebuilt the platform on the OpenTelemetry Collector framework, inheriting its extensible pipeline architecture while implementing Jaeger-specific features as extensions and components, enabling seamless integration with the OpenTelemetry ecosystem through native OTLP protocol support. The platform stores traces in Cassandra 4.0+, Elasticsearch 7.x/8.x, OpenSearch 1.0+, ClickHouse, or the embedded Badger database for development setups. Three sampling strategies control trace volume: head-based sampling with constant, probabilistic, and rate-limiting modes, tail-based sampling using the OpenTelemetry Collector processor that evaluates complete traces before storage decisions, and adaptive sampling that dynamically adjusts probabilities based on observed traffic patterns. Service Performance Monitoring computes RED metrics directly from spans, displaying request rates, error rates, and latency percentiles in the Monitor tab with drill-down from aggregate service views to individual traces. The web UI provides trace search with multi-field filtering, trace detail views with span timeline visualization, trace comparison across services, and dependency graphs mapping service relationships from actual traffic. Deployment options range from a single all-in-one binary for development to distributed collector-ingester-query configurations with Kafka intermediate buffering for production scale. 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.

An Airtable-style spreadsheet interface directly on PostgreSQL: Teable is an open-source no-code database where every table is a real Postgres table. Unlike tools that store records in a metadata abstraction layer, every Teable table is a real Postgres table with standard column types, so filtering, sorting, and grouping run at database speed, million-row tables answer complex filters in roughly 200 milliseconds without index tuning, and any PostgreSQL-compatible tool - psql, BI dashboards, ETL pipelines - can query the same data directly. The interface offers Grid, Kanban, Gallery, Calendar, and Form views as non-destructive overlays with their own filters and hidden fields, plus 20+ field types, formulas, comments, attachments, batch editing, undo/redo, and edit history. Collaboration is real-time with live cursors and instant sync across views, backed by Redis, and a REST API is auto-generated per table, largely compatible with Airtable API clients - alongside native SQL access for BI tools, analytics pipelines, and your own applications to JOIN and query directly, with no exports, API rate limits, or sync jobs. Global search spans all records, chart plugins handle quick visualization, and CSV and Excel import/export cover migrations. Where Airtable caps paid plans at 100K-500K rows and charges roughly $20 per user per month, a self-hosted Teable instance has neither limit: the Postgres database itself is the export if you ever leave. Built in TypeScript with NestJS, deployed via Docker with PostgreSQL and Redis, and licensed AGPL-3.0.

"Dead simple static HOMepage for your servER" - Homer's name is the spec. It is a fully static HTML/JS dashboard driven by one YAML file (assets/config.yml): list your services in groups with names, icons, tags, and URLs, and Homer renders a clean, fast landing page for everything you self-host. Because there is no backend, no database, and nothing to maintain, the container is tiny and effectively zero-maintenance - the entire operational surface is a text file you can version-control alongside your infrastructure. Despite the minimalism, the feature set is genuinely useful: smart cards add live data to service tiles via a type key - Pi-hole block statistics, AdGuard Home status, Jellyfin activity, Gatus and Home Assistant states, and dozens more integrations, with configurable periodic refresh. Fuzzy search jumps to any service as you type, keyboard shortcuts drive navigation, and multi-page support with item grouping keeps large homelabs organized. Theming covers built-in light and dark modes plus full custom CSS, tags get color-coded styles, and the whole dashboard installs as a PWA on phones and tablets. Icons come from Font Awesome or your own images. If Dashy is the maximalist dashboard and Homarr the drag-and-drop one, Homer is the minimalist: one YAML file, instant loads, and nothing that can break at 2 a.m.

Casibase lets organizations build AI-powered knowledge bases that answer questions from their own documents, connecting to 30+ model providers through a unified admin interface with RAG retrieval and multi-agent orchestration via MCP and A2A protocols. The platform plugs into OpenAI GPT-4o, Anthropic Claude, Meta Llama, Google Gemini, DeepSeek, Ollama local models, HuggingFace, Azure OpenAI, and additional providers, while embedding APIs from OpenAI Ada and Baidu handle vector representation of ingested documents. Document ingestion parses TXT, Markdown, DOCX, PDF, CSV, XLSX, and PPTX files with intelligent chunking strategies for optimal retrieval accuracy. The built-in chat interface provides real-time AI conversations with manual session handover for human agent escalation, and comprehensive chat session logging enables audit trails for compliance. Enterprise identity management integrates Casdoor for Single Sign-On supporting GitHub, Google, WeChat, and OIDC providers with fine-grained access control via the Casbin permission engine.

Teams tired of paying Salesforce or HubSpot per seat run EspoCRM: an AGPL-licensed PHP application with a fast single-page frontend over a REST API, covering sales, support, and marketing in one uncluttered interface. The sales core is complete - leads, contacts, accounts, opportunities with customizable pipeline stages, kanban views, calendars, meetings, and calls. Email is deeply integrated rather than bolted on: IMAP sync links messages to CRM records automatically, and mass email campaigns run with reusable templates, tracking, and Web-to-Lead forms feeding the funnel. Support teams get case management and a customer portal where clients track their own tickets and access a knowledge base. The real differentiator is the Entity Manager: create custom entities, fields, relationships, and layouts from the admin UI without code, with dynamic logic showing or hiding fields conditionally - EspoCRM is as much a business-application platform as a CRM. Formula scripting handles calculated fields and record automation in the free core; the optional Advanced Pack adds visual BPM process design and workflow rules. Role-based permissions with team and territory scoping, full-text search, reports, and a straightforward REST API for n8n or custom integrations round it out. Runs on PHP 8.3+ with MySQL, MariaDB, or PostgreSQL - unlimited users, zero per-seat fees.

On game night Sharkord carries voice, webcams, and screen sharing, and on Monday morning it carries the team's threaded chat, all from one server you control. For the gaming crowd, voice rooms offer noise suppression, echo cancellation, webcams up to 2160p, and screen sharing in VP8, VP9, H264, or AV1, with optional simulcast layers for slow viewers. An experimental Bridge app keeps push-to-talk and mute hotkeys working with a game in focus, and plugins add a music bot or a soundboard. For a family group, invite links can carry a role, a use limit, and an expiry, and replies, reactions, custom emoji, pins, and direct messages keep conversation casual, with uploads up to 2 GB each. For a small team, text channels sit in categories with threads, mentions, and search, roles stack with per-channel permissions for private rooms, and OpenID Connect sign-in works with Authentik, Keycloak, Zitadel, Entra ID, or Google Workspace. Admins cap storage per user or role and can sign upload URLs. There is no premium tier, no member cap, no ads, and no tracking, and a built-in marketplace installs plugins in one click. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Several EU data protection authorities have ruled Google Analytics deployments unlawful; Matomo (formerly Piwik) is the most complete open-source replacement - a full analytics platform with 30+ report types across visitors, actions, referrers, goals, and ecommerce. The self-hosted PHP/MySQL edition is free and keeps every byte of visitor data on your infrastructure, which matters more each year: several EU data protection authorities have ruled Google Analytics deployments unlawful, while Matomo configured for cookieless tracking is approved by France's CNIL for use without a consent banner. All reporting runs on 100% unsampled data - no extrapolation at high traffic volumes. The GDPR Manager handles data subject requests and deletion, with IP anonymization, retention controls, and Do Not Track support built in. A dedicated importer pulls your historical Google Analytics data so years of trends survive the migration. Core analytics cover campaigns, custom variables and dimensions, entry/exit pages, downloads, site search, and full ecommerce tracking with a comprehensive HTTP API for reporting and ingestion. Premium plugins extend the platform into Hotjar-class behavioral tooling - click and scroll heatmaps, session recordings, conversion funnels, form analytics, A/B testing - plus a tag manager and SAML SSO. For teams that need GA-equivalent depth with actual data ownership, Matomo is the realistic drop-in replacement.

Self-hosted and built around long reading, Omnivore saves articles, newsletters, and PDFs, renders web pages as clean text, remembers your place, and keeps every highlight searchable. Pages arrive from the web app's Add button or from Chrome and Firefox extensions that authenticate with an API key. Newsletters arrive through generated email addresses once an IMAP watcher or another mail bridge is set up. PDFs open in the same reader and accept highlights and notes just like articles. Labels, saved searches, and filters such as subscription:"Name" make a big library easy to slice. The RSS section follows your feeds, lets you add a story to the library or hide it, and can sort stories into topics when an OpenAI key is configured. Custom extractors scroll lazy-loaded pages, follow paginated articles, and strip pop-ups before saving. Rules trigger webhooks when pages are created or updated, which suits automatic labelling and other custom workflows. E-ink reading settings add double-tap page turns and volume-button scrolling, and Android and iOS apps sync the same library.

Archiving YouTube channels and playlists into a local media server becomes effortless with Pinchflat, a self-hosted media manager that automates downloading, naming, and organizing online video and audio libraries on disk. Instead of manually copying links into command-line downloaders, you define reusable Media Profiles with presets tailored for Plex, Jellyfin, Kodi, or raw archival storage, and then attach any number of YouTube channels or playlists as monitored sources. Fast Indexing polls RSS feeds or the YouTube API to detect newly published uploads within minutes while falling back to scheduled full scans so back-catalog videos are never missed. Granular source rules let you include or exclude YouTube Shorts and livestreams, filter titles by keyword patterns, enforce earliest upload cutoff dates, and set automatic retention windows that prune older files after a configured number of days. Built-in SponsorBlock integration marks or strips sponsor segments and embeds chapters alongside thumbnails, subtitles, and NFO metadata files so episodes appear cleanly inside your home theater library. You can also schedule Delayed Redownloads a few days after initial publication to capture higher-bitrate transcodes or crowd-sourced SponsorBlock tags, supply browser cookies for private playlists, and subscribe to any archived source in mobile podcast players through generated RSS feeds.

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.

Your AI coding agent has your API keys in its environment and unrestricted network access, which means one prompt injection away from sending those secrets anywhere. Pipelock closes that gap by sitting as a proxy between your agents and every outbound connection, scanning the actual content of HTTP, WebSocket, MCP, and Agent-to-Agent traffic before it leaves your server. An 11-layer scanner pipeline checks every request against 62 credential patterns covering AWS, GCP, Azure, GitHub, OpenAI, Anthropic, SSH keys, and database URLs, then inspects every response for prompt injection using 29 detection patterns with six-pass normalization that catches base64-encoded, leetspeak, and whitespace-obfuscated payloads. The MCP proxy wraps any Model Context Protocol server (stdio, HTTP, or WebSocket) with bidirectional scanning that detects tool description poisoning and mid-session rug-pull changes via SHA-256 fingerprinting. Every scanning decision produces a cryptographically signed action receipt that third parties can verify offline without trusting the agent or the vendor. The Operator Console provides a web dashboard for reviewing evidence scorecards, receipt timelines, agent sessions, enforcement decisions, and fleet posture at a glance. Cross-request taint tracking catches slow-drip exfiltration attempts that spread a secret across multiple calls. Canary tokens plant synthetic secrets that trip alerts the moment an agent tries to exfiltrate them. Pre-built Prometheus metrics and a Grafana dashboard provide real-time visibility into traffic volumes and block rates.
