Small tools that just work, right in your browser.
Missing Paint? Don't want to install a 200 MB app to crop a screenshot or scribble a note? These tools live in a browser tab. No signup, no backend, no telemetry — just open source utilities, hosted statically on GitHub Pages.
*the CDN sees your IP, nobody else.
Full-featured CodeMirror 6 editor — 20+ languages, linting, Prettier formatting, Vim/Emacs, command palette, and share-by-URL.
A rich-text editor for notes and documents.
A simple Paint-like drawing canvas.
Draw shapes, freehand and pen paths, and text; select, transform, and restyle; snap to a grid, undo/redo, autosave, and export to SVG or PNG.
Paste anything tabular into a fast virtualised grid — edit, sort, filter, and export anywhere. All client-side.
Merge, split, rotate, crop, watermark, stamp, fill forms, edit metadata, extract text, build PDFs from images — all client-side via pdf-lib + pdfjs.
Sketch on base planes with constraints and typed dimensions, then extrude, revolve, or combine primitives with booleans. Feature tree, undo/redo, autosave, and STL/GLB/PNG export — the Manifold kernel runs in a Web Worker.
Write Typst with syntax highlighting and a live preview; export to PDF, SVG, or PNG and share by link. The compiler runs in your browser via WebAssembly — nothing is uploaded.
Your data stays put — files never leave your device.
No install, no account, no waiting — a URL is the whole UX.
Open source — every line on GitHub, fork it / host it / PR it.
