Supacanvas

Quick-launch your AI-generated canvases from any tab.

Supacanvas allows you to see what your agent has built from anywhere: Cursor, Claude Code, Hermes Agent, Open Claw etc. Click the toolbar icon and your full canvas gallery docks on the right edge of any tab. Browse, search, filter by folder, and open any canvas in a new tab without losing the panel. — What it does — • Browse every canvas on your local server, with thumbnails, titles, and folders, in a side panel that doesn't dismiss when you click a card. • Search live across titles, descriptions, and tags. • Filter by folder with a single click. • Save any webpage by right-clicking and choosing "Save to Supacanvas." The full page body becomes a new canvas. • Save any selection the same way — highlight text or a region, right-click, save just that part. • Captures are sandboxed: <script> tags and inline event handlers are stripped before saving, and everything renders inside the supacanvas iframe sandbox in the viewer. — How it works — The extension talks only to http://localhost:7777 — the supacanvas server you run yourself. There is no cloud, no account, no sign-in, and no telemetry. Your canvases live as plain HTML files in ~/.supacanvas/canvases/ on your own disk. If the server isn't running, the panel tells you so and shows the exact command to start it. — Requirements — • Node.js • supacanvas CLI: npm install -g supacanvas • Server running: supacanvas serve — Privacy — Supacanvas does not transmit, log, or share any data. Network requests go only to http://localhost:7777 on your own machine. No remote hosts, no third-party scripts, no analytics. — Open source — MIT-licensed. Source, issues, and roadmap on GitHub. (~1,580 chars — scannable but substantive. Add your GitHub URL on the last line before submitting.) What changed from my earlier draft - Lead is one tight sentence, not a paragraph - Bullet groups under em-dash headers — easier to scan than ALL CAPS - Removed marketing-speak ("stay in flow", "in a persistent side panel that doesn't dismiss" became one bullet) - Privacy and Requirements moved below features, where reviewers expect them
