Malleable software for coding agents.
Use Claude Code and Codex to build your projects and reshape the app itself.
y is a real coding agent app at its core. Run multiple sessions at once — each its own isolated workspace, each picking the engine that fits, with real tool calls and code.
Open Modify and describe the change. Watch it get typed out: "change the ui to white and add a browser to the app." Hit submit and y starts rewriting itself.
No restart, no config file. The theme flips to light and a real browser panel slides in — exactly what was asked for, applied instantly.
