When an alert fires at 3 a.m., the live chart, the runbook, and the fix are already on one page of Oxynote, a self-hosted technical wiki. The chart is a Live Metrics block that runs its own Prometheus or SQL query and draws a time series, bar chart, or gauge. Several such blocks side by side make a dashboard inside the page. Around it, the editor works like Notion, with checklists, callouts, titled code blocks, Mermaid diagrams, Figma embeds, images, and files. Internal APIs get Stripe-style reference pages with the endpoint, a curl example, and a sample response beside the explanation. Mark a page reviewable and every edit lands in a draft. A block-aware diff shows renamed endpoints, fields, and reworded sentences in one red and green view until a reviewer approves. Freshness hooks watch GitHub files, container images, web pages, or dates, and remind maintainers when something a page depends on changes. Teammates edit together live and see who holds which block. Comments attach to a word, a diagram line, or a whole chart, with replies and an inbox for mentions. The Rubber Duck assistant edits pages and runs block queries with Anthropic, OpenAI, Google, OpenRouter, or a local Ollama model, and MCP lets Claude Code and Codex read and write the docs.

Design posters, social posts, presentations, invitations, resumes, thumbnails, and business cards in your browser with Doory, a self-hosted design editor that keeps your files, fonts, and brand assets on your own server. Start from one of ten starter templates or a blank canvas, then place text, shapes, lines, arrows, emoji, stickers, QR codes, and roughly 27,500 built-in icons anywhere on the page. Photo tools cover cropping, masks, filters, in-browser background removal, and 2x to 4x image upscaling, with stock photo search through Unsplash or Pexels. Layers can be renamed, locked, hidden, grouped, and reordered, while guides, snapping, rulers, per-page sizes, and format resizing keep multi-page designs tidy. Animations add 27 enter and exit effects, 12 emphasis motions, and 16 page transitions, plus Creative Commons music loops and sound effects, so decks can be presented live with speaker notes or exported as MP4, WebM, or GIF. Share links grant view, comment, or edit access with an optional password, and collaborators can pin comments, co-edit in real time, and roll back through version history. Brand kits store your colors, fonts, and logos so recurring posts stay on-brand, and exports cover PNG, JPG, SVG, and print-ready PDF with bleed and crop marks. An optional MCP server lets AI assistants create and fill designs from prompts, including bulk template filling from spreadsheet-style rows.

On a Doop design canvas every frame is real HTML, so Claude Code, Codex, Cursor, or any MCP client can design beside you as teammates watch every cursor and edit arrive live. Agents connect with one command or a one-click install and, once access is approved through OAuth, work as you and report their status and tasks on the canvas. The built-in Doop Agent has six roles, among them UX Lead, Copywriter, and Accessibility, picks up board cards and @mentions in comments, and runs on a connected ChatGPT subscription or an OpenAI, Claude, Gemini, or OpenRouter key. The editor covers frames, shapes, pen paths, rich text, flex layout, layers, pages, rulers, design tokens, and version history. Prototype mode wires clicks, hovers, and key presses to screen transitions, and the finished flow plays full screen or goes out as a shareable link. Marking a frame ready for dev can start an automation that queues agent steps, creates Linear tickets, or posts to Slack. Websites, live apps, GitHub repositories, and PDF pages import as starting points. Frames export as PNG, JPG, or PDF, or as public image links that re-render when the design changes.

Openfire is a self-hosted XMPP server that gives your organization its own instant messaging network, with one-to-one chat, persistent group rooms, and federation to other XMPP servers, all administered from a web console. Team members connect with any XMPP client on desktop, mobile, or the web and get presence, rosters, offline message delivery, and file sharing inside conversations. Multi-user chat rooms stay available around the clock with configurable history, moderation roles, and access controls, so a support channel or project room keeps its context instead of dissolving into scattered direct messages. The plugin catalog installs from inside the admin console and adds capabilities like message archiving and compliance monitoring, a browser-based chat client, HTTP file upload, and push notifications for mobile clients. An LDAP directory or an existing database can supply users and groups, so accounts stay in sync with the directory your organization already maintains. Server-to-server federation connects your users with contacts on other XMPP domains over encrypted connections, and load balancing spreads busy deployments across multiple instances. TLS certificates, encrypted client ports, and IP-based access lists for the admin console keep the deployment under your control from the first setup wizard onward.

In TeXlyre, two coauthors edit the same LaTeX or Typst file at once, and the PDF compiles inside the browser tab instead of on someone else's server. Start from a template: arXiv preprint, IEEE paper, Tufte book, Beamer deck. pdfTeX, XeTeX, and LuaTeX compile with BibTeX and Biber. Errors turn into readable cards that jump to the failing line. Live cursors show who is typing where. A shared link brings coauthors in, no accounts needed. Chat sits beside the editor, and comments can be discussed and resolved. Tracked insertions and deletions land in a review panel to accept or reject. Draw.io and TikZ editors open inside the project for shared diagrams. MathLive edits a formula under the cursor with a virtual keyboard. A bibliography panel tidies BibTeX, matches DOIs, and imports from Zotero and OpenAlex. Large files travel straight from one collaborator's browser to another. Projects export as ZIP, sync to a local folder, or back up to GitHub, GitLab, Gitea, and Codeberg. Vim, Emacs, and Helix keybindings are one setting away. The app installs as a progressive web app and works offline. Language servers like LTeX LS Plus, Harper, and Tinymist plug in through recipes beside your own signaling and TeX Live package servers.

Movie night should not depend on everyone pressing play at the same second; SyncWatch runs your own watch-party server so friends in different places watch the same frame together. The host controls play, pause, seeking, and playback speed for the whole room, and late joiners or drifting clients are corrected back to the shared position automatically. You build the program from uploads or direct HTTPS media links, with subtitles, audio, images, and documents handled in the same library. Rooms can be permanent or temporary, protected by passwords and member limits, with host, admin, and permission-group control over who may operate playback. Between scenes, people talk through public and private chat, on-screen danmaku comments, emoji, voice messages, or full-room voice. Anyone can share a browser tab, window, desktop, or phone screen into the room, so a clip, a game, or a presentation becomes the shared screen. The server also keeps friends, notifications, online presence, bans, registration approvals, and an operations log, so a private community can run itself without a platform account. Uploaded media is analyzed and thumbnailed automatically, with browser-compatible versions generated for awkward formats. Backups, data export, a recycle bin, mail verification, and network diagnostics round out the admin side.

Emailed copies of the same document, each with a different filename and a different set of edits, are where collaborative writing goes to die. LibrePaper keeps one living document in the browser instead: start a project in HTML, Markdown, Typst, LaTeX, or Quarto, or upload an existing one, and the editor renders the compiled result beside the source as you type. Readers highlight the exact passage they mean and comment on it, suggested edits land as tracked changes, and threads resolve on the text in real time. Finished work publishes to its own separate host, so scripts and interactive figures inside a document can never reach a reader's sign-in session. Nobody manages another password: sign-in runs through GitHub, Google, Microsoft Entra ID, ORCID, or any OpenID Connect provider, per-provider lists decide who may publish and who may only comment, and anonymous comments can be switched on for outside reviewers. Every project exports as a complete, independent copy from the command line, which also administers the deployment and can serve a document's tools to an AI agent over MCP. Operators get graphs, account management, and moderation, with per-account storage quotas, upload limits, and retention rules keeping a public instance under control. Four Docker containers behind Caddy with automatic HTTPS, one configuration file, and nightly backups of database and files complete the deployment.

Retrospectives, sprint poker, check-ins, and standups all get a home in Parabol, a meeting workspace that walks agile teams through each ritual one stage at a time and keeps every outcome in one place. A retrospective flows from icebreaker to reflect, group, vote, and discuss, with anonymous reflection cards that stay hidden until everyone is done writing, then cluster into themes before dot voting decides what deserves airtime; Start/Stop/Continue, 4Ls, and Mad/Sad/Glad templates are ready to use or customize. Sprint Poker estimates stories on Fibonacci, T-shirt, or custom scales, pulling backlog items from Jira Cloud, GitHub, GitLab, or Linear and pushing the agreed estimate back. Check-ins work through agenda items and task updates, while standups gather written answers on a recurring schedule so distributed teams stay current across time zones. A facilitator timer sets deadlines for asynchronous contributions, with optional Slack or Mattermost notifications to the team. Action items land on a shared task board with active, stuck, done, and future columns, and Pages hold real-time collaborative notes next to the meetings that produced them. Every meeting closes with a summary of attendees, discussion, and next steps that can be emailed to the team.

Hocuspocus is the WebSocket backend that turns a regular editor into a multiplayer one: two people open the same document, type at the same time, and watch each other's words appear in place, with every keystroke merged cleanly and no save conflicts to untangle later. The server speaks the Yjs synchronization protocol, so clients built with Tiptap, ProseMirror, Slate, Quill, or Monaco editors connect over a persistent connection and exchange small updates that the conflict-free data type orders correctly regardless of arrival sequence, and awareness messages carry cursor positions and presence so collaborators see who is in the document. Teams that outgrow one process add the Redis extension to balance connections across multiple server instances, reaching very large numbers of simultaneous editors on the same documents. Persistence extensions store documents in SQLite for small deployments or in a database or S3-compatible storage through your own fetch and store callbacks, the webhook extension notifies your application when documents change, throttling guards against abusive connections, and hooks for authentication and document loading let you enforce per-document permissions before anyone joins. Developers embed the server into an existing Node.js, Bun, Deno, or Cloudflare Workers runtime, or run it as the collaboration tier beside their main application, and offline-first clients queue changes locally and synchronize when the connection returns.

Folio is a self-hosted team wiki that stores every page as a plain Markdown file in a Git repository you own, while your team writes together in the browser in real time. People work in Reading, Live edit, or Source mode, keep editing offline until the connection returns, and watch changes land in the page history as commits they can restore. Data tables with nine column types, filters, and views sit beside the documents, and forms write submissions straight into those tables without requiring an account. Whiteboards, Mermaid diagrams, and a visual diagram editor cover the pictures, while uploads like PDF, Word, Excel, and PowerPoint files open as previewable pages inside the tree. Confluence spaces import with their trees, images, and whiteboards converted, so a migration keeps its structure instead of flattening into a pile of attachments. AI agents read and write the same pages through an MCP server with 41 tools, authenticated by personal tokens or OAuth 2.1, and the built-in assistant answers questions read-only or makes supervised edits. Administrators control access down to a single page, sign people in with SAML, SCIM, or OpenID Connect, hand out expiring share links, and publish a space as a public read-only website.
