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.

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.
