source AI Tools

Open source desktop IDE on an infinite zoomable canvas. You arrange Monaco editors, xterm.js terminals, embedded browsers, and Claude Code agent panels in freeform zoomable space instead of tabs. Panels can float, dock, or detach into separate windows, and layout persists per project. Built with Electron, runs on macOS, Windows, and Linux.
