Your team chat can be one executable on your own server: Campfire Rust runs rooms, direct messages, attachments, and search as a single binary that replaces the whole Ruby, Puma, Redis, Resque, and Thruster stack. Create rooms with access controls for projects, departments, or a private board discussion, and keep direct messages beside them for quick questions. File attachments arrive with previews, mentions pull the right person into a thread, and search finds the decision someone made months ago. Web Push notifications reach browsers and phones, so a quiet room still finds its people when it matters. Chatbots connect through a simple HTTP API for sending and receiving messages and attachments, which makes Campfire a home for build alerts, deploy notices, and support pings. Existing Campfire installs upgrade in place because the Rust binary reads the same SQLite database, storage layout, and signed cookies, with no data migration and no mass sign-out. Automatic TLS with Let's Encrypt certificates, HTTP/2, and Action Cable-compatible WebSockets are built in, and the whole system works on air-gapped networks that never touch the internet. Run it as your primary chat, as a backup for the day a hosted service goes down, or as a walled garden for executives and events.

Yet Another API Development Environment delivers a self-hosted alternative to Postman designed from the ground up for teams that need secure, collaborative API development without sending sensitive credentials through third-party cloud services. The multi-user system manages team members with role-based permissions and supports external authentication through OAuth2 and OIDC providers, while all data persists in an H2 file-based database that survives container and server restarts. REST and WebSocket request testing includes environment variable substitution, request chaining, and Markdown documentation for each endpoint. The JavaScript scripting engine runs request and response scripts for automated testing and data extraction, with cron job scheduling and API-triggered execution for continuous integration workflows. Collections import directly from OpenAPI specifications and Postman exports, while outbound export generates request code in multiple languages and frameworks. The browser extension proxy for Chrome and Firefox routes requests through the user's browser to bypass CORS restrictions when testing localhost and internal APIs, with an alternative server-side proxy for headless environments. Single-file data import and export simplifies backup and migration between instances. The React and Vite frontend ships with dark mode enabled by default.

Atlas delivers a complete business operations platform in a single Docker Compose deployment, replacing the need for separate CRM, HRM, project management, invoicing, and file storage subscriptions. The CRM module provides pipeline management with Kanban views, contacts, companies, deals, leads, forecasting, saved views, and web-to-lead forms with Gmail integration for per-user email tracking inside deal timelines. HRM handles employees, departments, org charts, leave management, and attendance tracking. The invoicing system generates professional invoices with recurring billing, customizable templates, and payment tracking. Agreements provides PDF contract generation with legally-binding e-signatures, sequential signing workflows, counterparty linking, audit trails, and automated reminders. Projects integrates time tracking, billing, client management, budgets, and reporting in one view. Drive offers file storage with versioning, sharing, comments, activity logs, and password-protected links with Google Drive import and export. The calendar syncs bidirectionally with Google Calendar across month, week, day, year, and agenda views. Write provides rich text documents with cover images, comments, and templates, while Draw adds an Excalidraw-based whiteboard canvas with PDF export and presentation mode. The platform supports five languages, multi-tenant isolation, role-based permissions, and includes an Odoo importer that ingests res.partner, crm.lead, and CRM activity CSV exports for migration. Built on React, TypeScript, Vite, TanStack Query, and Zustand on the frontend with Express, Drizzle ORM, PostgreSQL, Redis, and BullMQ on the backend. 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.

The drawing surface inside WebRTC conference tools like Meetzi and the LAMS online-learning platform is Whiteboard (by cracker0dks) - a lightweight Node.js collaborative sketchboard built to be embedded and customized, which also slots into Nextcloud via the External Sites app. Everyone opening the same whiteboardid URL parameter draws on the same board, with remote user cursors visible live, per-user undo/redo, and an indicator showing the smallest participating screen so nobody draws outside a colleague's view. Content handling goes beyond pen strokes: drag-and-drop or paste images and PDFs from any PC or browser, then resize, rotate, and draw over them on canvas or background; add text and sticky notes; hold Shift for angle-snapped lines and perfect squares. Every function has a keybinding - deliberately friendly to pen displays like Wacom and XP-Pen whose hardware buttons map to shortcuts. Boards save to image or JSON (with reload), export directly to Nextcloud via WebDAV, and persist across restarts with the file-database option. A REST API with bundled interactive docs allows full programmatic control, an optional access token locks down uploads, and YAML configuration tunes behavior and performance. MIT-licensed and reverse-proxy friendly.

Scrumboy is a Kanban and sprint management tool that ships as a single Go binary backed by SQLite, deploys in under ten seconds via Docker, and uniquely integrates with AI coding agents through a standards-compliant MCP JSON-RPC endpoint. The dual-mode architecture supports Full mode with bootstrapped authentication, TOTP two-factor auth, OIDC/SSO integration through Keycloak, Authentik, Auth0, or Entra ID, role-based access control across Owner, Admin, User system tiers plus per-project Maintainer, Contributor, and Viewer roles, and Anonymous mode that generates instant shareable boards accessible via unique URLs with zero signup requirement. Custom workflows allow user-defined lane configurations per project including designated "Done" lanes, while sprints with configurable one or two-week cycles include board-level sprint filtering and the ability to disable and re-enable sprint tracking without losing history. Real-time Server-Sent Events power instant multi-user board updates, and outbound webhooks deliver JSON payloads to registered URLs when domain events fire with HMAC signature verification. The MCP endpoint at /mcp/rpc enables native integration with Cursor, Claude Code, and other AI agents through OAuth 2.1 with PKCE authorization, while API access tokens support CLI automation and CI/CD pipelines. Additional capabilities include VoiceFlow voice commands, per-project sticky-note walls, Markdown and Mermaid diagram support in task notes, append-only audit trails, VAPID Web Push notifications, SMTP password reset, Trello import, JSON backup with merge/replace/copy strategies, and 22-language internationalization.

MiroTalk WebRTC is the front desk for your own video meeting platform, where users register, schedule rooms across your MiroTalk servers, and invite guests by email or link. Each account gets a personal dashboard of upcoming, recurring, and past meetings, with room links ready to copy the moment a call needs to happen. Scheduling works for the whole MiroTalk family, SFU group calls, P2P chats, and broadcast or direct-call rooms, so one calendar front door serves every meeting style you run. Invitations travel by email or plain shareable links, and guests join from any modern browser with no account and no downloads. Turn on SaaS mode and the same platform sells access, with monthly, annual, and lifetime plans handled by Stripe checkout and webhooks while free mode stays completely open. A documented REST API lets your own systems create rooms and manage users, and the official Docker image with MongoDB gets the whole front desk online in minutes. 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.

Talkyard combines five discussion formats in one platform: StackOverflow-style Q&A with accepted answers, Reddit-like upvote sorting for ideas, threaded forums, real-time chat channels, and embeddable blog comments. Running separate tools for each conversation type fragments community knowledge across disconnected systems, but Talkyard keeps it all searchable in one place. Question askers mark accepted answers, and community voting surfaces the best solutions for future visitors. Idea topics sort by upvotes for crowdsourced feedback prioritization and product decisions. Chat channels handle real-time day-to-day conversation, while forum threads preserve important discussions that need to remain findable months later. The embedding capability goes beyond blog comments: entire Talkyard forums can live inside iframes on your existing website with automatic deep-linking and iframe auto-resizing, adding community discussion to any page without rebuilding your site. Docker Compose containers run with dropped capabilities, no-new-privileges enforcement, non-root processes, health checks, and automatic log rotation. Multi-site hosting serves multiple communities from one installation with isolated databases and separate domains. Automated upgrades pull new images and restart services without intervention. ElasticSearch indexes every discussion format for instant full-text search. The Scala backend with TypeScript frontend stores data in PostgreSQL with automatic Let's Encrypt HTTPS. Runs on a RepoCloud VPS with guaranteed CPU, RAM, SSD, root SSH, and browser console. AGPL licensed.

Write your knowledge as plain Markdown files, and WikiDocs turns the folder into a searchable, versioned wiki with no database to set up or back up. Pages carry YAML front matter, so the whole wiki can be copied, archived, or opened in any text editor. An editor with a formatting toolbar handles headings, lists, task lists, links, and images, and pictures can be pasted straight from the clipboard. Math is typeset with KaTeX, Mermaid renders diagrams such as ER models and mind maps, and code blocks get syntax highlighting. Every save keeps a revision, a versions dialog lists them, and deleted pages wait in a trash where they can be restored or erased. Attachments upload and download from any page, namespaces build a page tree in the sidebar with pinned pages on top, and full-text search highlights every match. Public mode publishes a read-only knowledge base, private mode requires sign-in, and administrator and user accounts are managed in the app. Settings cover the wiki title, owner notice, privacy banner, language, timezone, light or dark template, and accent color, and every page has a print button. A desktop app keeps files on your computer and syncs with your self-hosted instance, while a REST API with Swagger documentation lets other tools read and write pages.

Teams that ship one app in many languages keep every string, translator, and reviewer in a single workspace by hosting their own Traduora translation management platform. Developers import the files they already have: JSON, YAML, PO, XLIFF, CSV, Android XML, iOS Strings, Java properties, PHP array, or RESX. Each string becomes a term that can carry a context note and colored labels. A search bar and a label filter narrow long lists in seconds. Translators open a locale and type inline beside a reference language, with per-locale progress showing how much is finished and a toggle that hides what is already done. Colleagues join by email invitation as admins, editors, or viewers, with optional Google sign-in. Build pipelines get their own API clients, each with a role, to fetch and push translations over a REST API. Exports go back out in whichever format each platform wants, with fallback-locale and untranslated-key options. Mobile and web teams can keep iOS, Android, and website copy in sync from a single source of truth.

Your entire mail system can live in one self-hosted suite with OpenMail, from SMTP, IMAP, and POP3 delivery to three-pane webmail and the admin console that runs it. Standard clients such as Thunderbird, Apple Mail, and phone apps connect over SMTP ports 25, 587, and 465, IMAP ports 143 and 993, and POP3 ports 110 and 995, while people use the three-pane webmail with folder tree, conversation list, and reading pane at port 3000. You read, write, reply, forward, batch-organize, drag messages between folders, filter stars, search sender, subject, and body text, and follow conversations threaded automatically by their References headers. The rich-text composer autocompletes recipients, accepts dragged attachments and pasted screenshots, saves drafts every 12 seconds, sends on a schedule, and inserts reusable templates imported from HTML or generated with AI. Any OpenAI-compatible endpoint can draft replies, translate mail into twelve languages, and summarize messages, with provider keys encrypted on your server. Administrators get real-time mail statistics with 14-day send and receive trends, user quotas and bans, multi-domain aliases and catch-all addresses, outgoing queue visibility, and audit logs. Adding a domain generates DKIM keys and copy-ready SPF, DKIM, and DMARC DNS records with one-click checks, while rule-based spam scoring, TOTP two-factor authentication, and role-based permissions protect accounts in ten interface languages including right-to-left Arabic and Urdu.

Scoold brings Stack Overflow-style Q&A to a server you control, so answers get voted, accepted, and found again instead of scrolling away in chat. Askers get a Markdown editor with live preview, tags, and emojis, and the form suggests similar questions and flags likely duplicates before anything is posted. Answerers collect upvotes, accepted answers, reputation points, and badges, including custom ones with your own text, icon, and color. Authors and moderators can restore any earlier revision, because every edit is kept. Searchers can use Lucene syntax such as exact phrases, wildcards, and boolean operators. Admins split one site into private spaces, up to ten in the free edition, and choose how people sign in: email and password, LDAP, or social providers such as Google and GitHub. They can also back up and restore data, import a Stack Overflow for Teams export, and follow a dashboard of questions, answers, traffic, and active members. Builders get a REST API with OpenAPI docs, signed webhooks, Zapier and n8n connectors, and an optional MCP server for AI assistants. Color themes include a dark mode, Mermaid diagrams and KaTeX formulas can be switched on, and right-to-left languages are supported. SAML, SCIM, file uploads, and chat integrations are Pro-edition features. 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.

Real-time collaborative Markdown behind your own firewall: HedgeDoc (formerly CodiMD, descended from HackMD's open-source edition) keeps team notes on team infrastructure. Share a note's URL and collaborators are editing together instantly - live cursors, changes appearing keystroke by keystroke - in a three-mode interface that toggles between raw Markdown, rendered preview, and side-by-side split. The Markdown dialect is extended where engineers need it: Mermaid, Graphviz, and Vega-Lite diagrams, MathJax for equations, syntax-highlighted code blocks, embedded content, and a presentation mode that turns a note into reveal.js slides with a single YAML header. A dropdown permission system controls each note - freely editable, limited to signed-in users, or locked read-only - and published notes become clean read-only pages for wider distribution. Revisions track every change with the ability to revert to any earlier version. The AGPL-3.0 codebase is light enough to run on a Raspberry Pi and deploys via Docker with PostgreSQL, MySQL, or SQLite. Authentication covers LDAP, SAML, OAuth2, and email. It deliberately stays a focused document editor - no page trees or kanban - and does that one job with excellent keyboard-first ergonomics for meeting notes, RFCs, runbooks, and shared scratchpads.

Governed by the non-profit Codeberg e.V. with over 150 contributors and quarterly major releases reaching v16.0 in July 2026, Forgejo delivers a complete code collaboration platform in a single Go binary that runs comfortably on 512 MB of RAM — providing full Git hosting with SSH and HTTPS, pull requests with inline code review, issue tracking with labels and milestones, kanban project boards, wikis, and an integrated package registry supporting Docker, npm, PyPI, Maven, NuGet, and Cargo. Forgejo Actions provides GitHub Actions-compatible CI/CD with reusable workflows, OpenID Connect for secure third-party access, ephemeral runners for autoscaling, and dynamic matrix support for complex build pipelines. The platform implements ActivityPub-based forge federation allowing issues, pull requests, and stars to work across independent instances — enabling a decentralized development ecosystem similar to how Mastodon federates social networks. Organizations and team permissions provide fine-grained access control, while LDAP, OAuth2, and OpenID authentication integrate with existing identity infrastructure. Code search indexes repositories for fast discovery, LFS handles large files efficiently, and mirror synchronization imports repositories from GitHub, GitLab, and other forges. Deploy via a single static binary, Docker container, or official Helm charts with SQLite for small instances or PostgreSQL and MySQL for production workloads.
