Point OBS or a hardware encoder at Restreamer's built-in RTMP or SRT ingest and it serves your website while rebroadcasting to YouTube Live, Twitch, Facebook, Vimeo, TikTok, LinkedIn, PeerTube, and anything else that accepts RTMP, SRT, or HLS - a complete self-hosted live-streaming server from datarhei. That multistreaming normally costs a monthly Restream.io subscription; here it's one FFmpeg process per destination on your own hardware. The web UI is genuinely approachable, with a wizard that walks beginners through camera setup, while professionals get the full surface: multiple audio/video inputs (USB, RTSP network cameras, virtual devices), codec and processing settings, separate audio muxing, and hardware acceleration via Nvidia CUDA, Intel VAAPI, or Raspberry Pi. Serving your own audience is first-class - a built-in Video.js player embeds in your site, a ready-made publication website streams without any embedding work, HLS chunk sizes are tunable, and automatic Let's Encrypt handles HTTPS. Viewer and bandwidth monitoring with limits keeps traffic costs predictable, and it's GDPR-friendly: no third-party provider, no audience data stored. A fully Swagger-documented REST API drives automation. SRT support keeps latency under a second.

Spotify economics without the subscription or catalog gaps: Navidrome, the reference self-hosted music server, streams your own FLAC, MP3, and ALAC collection from a single Go binary with a React/Material UI web player. Its Subsonic/OpenSubsonic API compatibility is the superpower: 50+ existing clients work out of the box, from Symfonium and DSub on Android to Feishin and Sonixd on desktop, plus Android Auto, CarPlay, and Android TV apps. Transcoding is server-managed and FFmpeg-backed - FLAC direct-plays at home and downsamples to MP3, AAC, or Opus over mobile bandwidth, with the OpenSubsonic transcoding extension letting clients declare capabilities and receive per-track direct-play or transcode decisions automatically. Multi-user support gives every account its own play counts, favorites, ratings, and playlists, and multi-library support scopes different collections to different users. The feature list covers serious listening: Last.fm and ListenBrainz scrobbling, artist bios and images, embedded and external lyrics, audiobook bookmarks, saved play queues that resume on another device, internet radio, jukebox mode, and M3U playlist auto-import kept in sync with your folder. Resource usage is famously low - it runs happily on a Raspberry Pi and scales to six-figure track counts.

ILLA Builder turns internal tool development from weeks of custom frontend work into hours of drag-and-drop assembly, combining a visual canvas of 60+ UI components with direct connections to over 20 data sources. The TypeScript frontend, powered by ILLA Design, offers data grids backed by MUI X Data Grid Premium, charts, forms, rich-text editors, PDF viewers, QR code scanners, calendar widgets, map embeds, and video players. Each component supports Handlebars-style expression bindings that reference query results, widget state, or global variables, while the reactive execution tree resolves dependencies in topological order and re-evaluates downstream properties whenever upstream values change. Data connectors provide GUI-driven access to PostgreSQL, MySQL, MongoDB, MSSQL, Supabase, Redis, Firebase, CouchDB, Airtable, Google Sheets, Stripe, AWS S3, Hugging Face models, and REST or GraphQL endpoints without writing connector code. Real-time collaboration through WebSocket lets multiple developers edit the same application simultaneously with live cursor tracking and synchronized Redux state. ILLA Flow adds workflow automation triggered by schedules or webhooks, chaining actions across data sources. The Go backend handles application state, resources, and attribute-based access control using PostgreSQL for persistence, Redis for caching, MinIO for file storage, and Envoy for API ingress. Deploys as a single Docker container on port 2022 or scales horizontally on Kubernetes. 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.

Created by the developer behind Uptime Kuma and carrying over 23,000 GitHub stars, Dockge brings the same clean, reactive design philosophy to Docker Compose stack management with a web interface that makes Portainer's compose handling feel like editing YAML in a terminal over SSH. The interactive editor provides syntax highlighting, inline validation, and a live preview of your compose.yaml files while keeping every stack stored as a standard file on disk in /opt/stacks by default, meaning you can seamlessly switch between the web UI and the docker compose CLI without lock-in or proprietary database formats. Real-time WebSocket updates stream pull progress, container start/stop transitions, and build output directly to the browser with no polling delays. The built-in web terminal opens a shell session inside any running container for quick debugging, while the docker-run-to-compose converter transforms single-container run commands into proper compose.yaml definitions with one click. Multi-agent support introduced in version 1.4.0 connects multiple Docker hosts to a single Dockge dashboard, enabling centralized management of stacks distributed across different servers. Image update detection shows which stacks have newer versions available, and one-click updates pull the latest images and recreate containers without manual intervention. The stack is a single Docker container running on Node.js with Socket.IO for reactivity and stores no external database. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Tools and applications that already speak S3 can use RustFS as their storage backend, so backup jobs, data pipelines, and services keep working while the data stays on infrastructure you control. A built-in web console on port 9001 manages buckets, object uploads and downloads, access keys, users, groups, and IAM policies, with a status page for cluster health, capacity, and scanner activity. Versioning, Object Lock retention, bucket quotas, and server-side encryption with Vault or AWS KMS backends protect objects once they land. Lifecycle rules expire or transition data, and tiering moves cold objects to remote targets such as Amazon S3 or Wasabi. Bucket replication and site replication keep clusters in sync, and event notifications call webhooks when objects change. Single-node mode suits a lab or small server, while distributed mode adds erasure coding, bitrot protection, background healing, and pool expansion or decommissioning as capacity grows. Sign-in works with local users, OIDC single sign-on, or OpenStack Keystone, and FTPS and WebDAV are available by default, with SFTP and the Swift API as opt-in builds. A preview of S3 Tables exposes an Iceberg REST catalog for tools such as DuckDB and PyIceberg, and a documented migration path moves existing MinIO deployments across. Typical uses include backups, container registries, logs and traces, data lakes, and AI training sets. 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.

Amplication turns entity definitions into production-ready backend services, generating NestJS with Prisma and Apollo GraphQL for Node.js or ASP.NET Core for .NET, eliminating months of boilerplate. The plugin-driven Data Service Generator hooks into code generation lifecycle events, enabling teams to inject CI/CD manifests, proprietary authentication schemes, testing configurations, and cloud-specific deployment targets for AWS, Azure, and GCP without forking the core generator. Blueprint templates encode organizational architecture standards, security policies, and coding conventions into reusable foundations that keep every generated service consistent across the engineering organization. Jovu AI translates natural language requests into entities, relationships, fields, modules, DTOs, and custom API actions, automatically aligning each resource with predefined standards. Generated services include full CRUD operations with input validation, Swagger/OpenAPI documentation, authentication middleware, database-agnostic ORM via Prisma, optional React Admin interfaces, and Jest test scaffolding. Code output syncs to Git repositories as pull requests, preserving standard review workflows while letting developers edit every generated line and add custom business logic. Supports PostgreSQL, MySQL, and MongoDB as database targets. Over 16,000 GitHub stars with enterprise adoption. Apache 2.0 licensed.

SOGo adds shared calendars, address books, and a modern webmail interface to your existing Dovecot, Postfix, or Cyrus mail setup, turning familiar infrastructure into a full Exchange competitor. Rather than replacing your IMAP and SMTP servers, SOGo layers collaboration on top of them, becoming the missing link between raw mail delivery and what users actually expect from a workplace communication platform. The ActiveSync implementation synchronizes email, contacts, calendars, and tasks natively with iPhones, Android devices, and Windows without requiring users to manually configure CalDAV endpoints. CalDAV and CardDAV compliance ensures Apple Calendar, Thunderbird (via the official SOGo Connector extension), GNOME Evolution, and Android via DAVx5 all connect without plugins or workarounds. The web interface uses AngularJS Material design with responsive layouts, offering folder management, drag-and-drop calendar scheduling, contact groups, resource booking, and delegation. Shared calendars support free-busy lookups, iMIP event invitations, and per-user ACL permissions for fine-grained access across organizational units. Built on Objective-C with the GNUstep foundation, SOGo delivers exceptional performance: hundreds of concurrent ActiveSync connections from mobile devices alongside webmail and calendar traffic with sub-second response times. With 2,095+ stars and 116 releases, the project has proven its stability in production environments supporting thousands of users. The Docker deployment runs alongside PostgreSQL and memcached.

With 10,100+ GitHub stars and 75 releases over a decade of continuous development, Healthchecks is the open-source cron job monitoring service that catches failures your other monitoring tools miss — the jobs that silently stop running, the backups that never completed, the nightly reports that disappeared without error. The dead man's switch architecture requires zero agent installation: your cron jobs, scripts, and services ping a unique URL via HTTP request or email, and Healthchecks alerts you only when a ping does not arrive within the configured Period and Grace Time window. Each check supports cron expression scheduling, optional start, success, and failure signals for measuring execution time, and HTTP body keyword filtering for intelligent alert routing. Twenty-five notification integrations cover every channel teams actually use: Slack, Discord, Microsoft Teams, PagerDuty, Opsgenie, Splunk On-Call, Telegram, Signal, WhatsApp, SMS, email, webhooks, GitHub Issues, Pushover, ntfy, Gotify, Matrix, Mattermost, Zulip, Pushbullet, PagerTree, Spike.sh, and Trello. The web dashboard provides a visual grid showing real-time status with color-coded badges and per-check integration toggles. Monthly, weekly, and daily email reports summarize uptime trends with checks sorted by downtime duration. Team management supports projects with member roles and read-only access. Prometheus metrics expose check health and grace state for Grafana dashboards. WebAuthn and TOTP two-factor authentication secure accounts. Deploy via Docker images available for amd64, arm/v7, and arm64 architectures. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. BSD 3-Clause licensed.

Replacing HubSpot, Zendesk, Intercom, and Linear with a single self-hosted platform, erxes delivers an Experience Operating System trusted by over 4,000 GitHub stars and built on a modern Nx-powered monorepo architecture. The core ships with six foundational modules — My Inbox for omnichannel conversations across email, web chat, voice, and Discord; Contacts for unified customer profiles; Products for catalog management; Segments for behavioral targeting; Automation for visual workflow builders; and Documents for template generation. Beyond the core, a plugin marketplace activates Frontline for ticket management and omnichannel support queues, Sales for deal pipelines and lead scoring, Operations for project boards with cycle management, Content for headless CMS and knowledge bases, and Team for employee directories, time clocks, and internal chat. The technical stack combines GraphQL Federation with Apollo Server v4 and tRPC v11 microservices on Node.js, React 18 micro-frontends via Rspack Module Federation with TailwindCSS 4, MongoDB with Mongoose for persistence, Redis for caching, BullMQ for job queues, and Elasticsearch for full-text search. Deployment supports Docker Compose orchestration with automatic service discovery across all plugin containers. The Global Profile architecture enables agencies to manage multiple client brands under a single login with separated data stores. iOS and Android SDKs embed the messenger widget directly into mobile applications. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPLv3 licensed.

Over 2,500 open-source projects and companies in more than 165 countries localize with Weblate - the libre continuous localization platform and the standard self-hosted answer to Crowdin and Lokalise. Its defining trait is that translations live in the same version control as your code: Weblate talks directly to Git and Mercurial, pulls new source strings automatically via webhooks, and pushes finished translations back either as direct commits or as pull/merge requests on GitHub, GitLab, Gitea, Bitbucket, Azure DevOps, Gerrit, or Pagure. Every translator is properly credited in the commit history. For translators, it is a full computer-aided translation tool: translation memory, glossaries, customizable quality checks that catch placeholder and formatting mistakes, propagation of identical strings across components, and automatic suggestions from machine translation services - DeepL, Amazon Translate, LibreTranslate, and others, with per-service priorities and support for custom Python engines. It handles the format zoo (gettext PO, JSON, YAML, Android XML, iOS strings, and dozens more) and supports crowdsourced workflows with granular access control, workspaces, two-factor authentication, and reviewer approval steps. A REST API, CLI client, and add-on system automate everything else. Built on Python/Django, GPL-licensed, with no per-string or per-seat pricing when self-hosted.

With over 7,100 GitHub stars and 200 contributors since 2016, Mailu has become one of the most popular self-hosted email solutions, delivering a complete production-ready mail server stack as pre-configured Docker containers that eliminate weeks of manual setup. The platform bundles Postfix for SMTP and Submission with auto-configuration profiles for Thunderbird, Outlook, and mobile clients, Dovecot for IMAP and POP3 with full-text search across email attachments, Rspamd for intelligent spam filtering with auto-learn Bayesian classification, greylisting, SPF and DMARC validation, and ClamAV for antivirus scanning of attachments with configurable malicious file blocking. The web administration interface provides global admin controls, per-domain delegation, user quota management, domain aliases, custom routing rules, and announcement capabilities. Users access self-service features including aliases, auto-reply, auto-forward, fetched accounts from external mailboxes via fetchmail, and Sieve filter management through ManageSieve. Security features include enforced TLS on all connections, automatic Let's Encrypt certificate provisioning, outgoing DKIM signing, DANE and MTA-STS support for transport security, and Snuffleupagus PHP hardening for the web interface. The setup wizard at setup.mailu.io generates complete Docker Compose configurations tailored to specific deployment requirements. All components are free and open-source software with zero proprietary dependencies and no tracking. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT 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.

TencentDB Agent Memory provides a team-level memory hub that transforms AI agent conversations, documents, and codebases into four governed, shareable memory assets: Chat Memory for conversation history, Skills extracted from completed tasks, LLM-Wiki built from document ingestion, and Code-Graph generated from codebase analysis. The four-tier semantic pyramid structures long-term memory from L0 raw conversation capture through L1 episodic extraction and L2 scenario aggregation to L3 persona synthesis, enabling hierarchical drill-down via node and result references instead of flat vector recall. The Node.js Gateway sidecar handles capture, extraction, storage, recall, and pipeline scheduling through RESTful HTTP v2 endpoints on port 8420, while the Memory Proxy intercepts Anthropic-format API calls to inject team memory context into Claude Code, CodeBuddy, and other coding agents transparently. Local SQLite with the sqlite-vec extension provides the default storage backend with hybrid BM25 keyword plus vector embedding plus reciprocal rank fusion retrieval requiring zero external API dependencies. Teams manage ownership, versions, status, visibility, usage counts, and agent bindings through the Memory Hub dashboard with role-based access control separating System Admin and team-level Admin and Member permissions. Official TypeScript and Python SDKs provide programmatic access for custom framework integration beyond the built-in OpenClaw plugin and Hermes Agent adapter. 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 16,800 GitHub stars and growing rapidly, Maxun has become the go-to open-source platform for teams who need structured web data without writing scrapers. The TypeScript-based platform provides a no-code visual recorder that captures point-and-click interactions in real-time browser sync, automatically generating reusable extraction robots that handle pagination, infinite scrolling, and dynamic content. LLM-powered extraction accepts natural language prompts like "Extract 10 companies from the Y Combinator website" without requiring a URL — Maxun identifies the source and performs the extraction autonomously. The platform handles authentication-protected pages, adapts automatically to website layout changes through self-healing selectors, and exports directly to Google Sheets, Airtable, or any destination via webhooks. Robots run on configurable schedules with cron-based timing, turning any website into a perpetually fresh RESTful API endpoint. The crawl engine discovers and processes linked pages across entire domains with configurable depth and URL filtering, while the search capability runs automated queries across multiple engines. Official Node.js and Python SDKs provide programmatic control over robot creation, execution, and data retrieval, with MCP integration enabling direct connection to AI tools like Claude. The n8n community node enables workflow automation without custom code. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPLv3 licensed.

Calendars, to-do lists, journal entries, and contacts, synced over the open CalDAV and CardDAV standards nearly every client already speaks: Radicale is a small pure-Python server that works with Thunderbird, DAVx5 on Android, Apple Calendar and Contacts, GNOME, and many more. Its defining design choice is radical simplicity: there is no database. Events live as plain .ics files and contacts as .vcf files in an ordinary folder structure, which makes backup a copy command, migration a move, and disaster recovery a matter of reading text files. The server works out of the box with no complicated setup, then grows as needed: flexible authentication (htpasswd files among other methods), per-collection authorization rules, TLS-secured connections, and a plugin system for extending storage, auth, and rights handling. Built-in limits on parallel connections, file sizes, and failed authentication attempts harden it for network exposure behind a reverse proxy. A bundled web interface handles creating and managing calendars and address books - useful since many clients cannot create collections themselves. Maintained since 2011 with 140+ contributors, GPLv3-licensed, and light enough to run on the smallest VPS or a Raspberry Pi.

TeamPass is a dedicated on-premise password manager built specifically for teams that need collaborative credential sharing with fine-grained access controls. Role-based access control defines user permissions through hierarchical folder trees where each folder and item can be independently set to write, read, or no access against assigned roles, enabling organizations to segment credentials across departments without exposing sensitive data. Passwords are encrypted in the database using Defuse PHP Encryption with per-installation unique saltkeys, while two-factor authentication supports configurable RFC 6238 TOTP profiles with custom digits, period, and algorithm settings alongside Duo Security and Yubico hardware key integration. LDAP and Active Directory native integration enables enterprise SSO with automatic user provisioning. The Security Posture Dashboard surfaces weak, reused, breached, overdue, no-expiry, widely-shared, and unreadable credentials through indicator cards that filter and deep-link directly to items. Secure Send creates expiring, view-count-limited one-time links optionally protected by recipient passphrases for sharing credentials with external users. Import from Bitwarden, LastPass, 1Password, and KeePassXC through a unified source selector, with export to encrypted offline files. Email notifications, password expiration policies, custom fields, and attachment support round out item management. 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.

With 24,000 GitHub stars and infrastructure processing over 100 million clicks and 2 million links monthly for marketing teams at Twilio, Buffer, Framer, Perplexity, and Vercel, Dub is the most widely adopted open-source link attribution platform — unifying branded short links, real-time conversion analytics, and affiliate programs in a single self-hostable tool. Create short links on custom domains with built-in QR code generation, device and geographic targeting rules, A/B testing for destination URLs, deferred deep linking for mobile apps, and custom social media preview cards. The attribution engine tracks the complete customer journey from first click through lead capture to final sale, calculating lifetime value, retention rates, and multi-touch attribution across campaigns. Real-time analytics visualize clicks, leads, and revenue with filtering by geography, device, browser, referrer, operating system, and UTM parameters — plus an "Ask AI" feature that generates personalized reports from natural language queries. The partner program module enables embedded referral and affiliate programs with custom reward structures, automated payouts, and partner dashboards for product-led growth. Programmatic link creation via native SDKs for TypeScript, Python, Go, PHP, and Ruby supports enterprise-scale campaigns with real-time webhook notifications on link events. Migration assistants import existing links from Bitly, Rebrandly, and Short.io with redirects preserved. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPLv3 licensed.

Paste one SQL query result into a browser and get an interactive entity-relationship diagram instantly, with no installations, no credentials, and no account required. ChartDB's "Smart Query" runs a single statement in your existing database client that exports table definitions, relationships, indexes, and column types as JSON metadata, meaning the application never touches your database passwords. The canvas renders draggable entities with cardinality markers, collapsible grouping areas, and sticky notes for documentation. AI-powered DDL export generates migration scripts between dialect pairs like PostgreSQL to MySQL or SQLite to CockroachDB, analyzing your schema to produce target-specific DDL with correct type mappings and constraint translations. Import paths cover Smart Query JSON, raw DDL scripts, and DBML files from tools like dbdiagram.io. The AI layer connects to OpenAI or any compatible inference server including local vLLM instances running models like Qwen2.5-32B. Database coverage includes PostgreSQL (with Supabase and Timescale extensions), MySQL, SQL Server, MariaDB, SQLite (with Cloudflare D1), CockroachDB, ClickHouse, and Oracle. Exports to SVG with inline styles or SQL DDL in any target dialect. Ships as a React/Vite frontend behind Nginx in Docker, deployable on RepoCloud with dedicated VPS resources under the AGPL-3.0 license.
