YNot backed by Y Combinator, Waku is an open‑source desktop app that consolidates the agent CLIs you already use into a single, fast graphite window, all on your machine.

It drives the agents you already use Native down to the frame Rust and GPUI — the GPU‑accelerated framework behind Zed. The interface launches instantly and scrolls smoothly through years of transcripts, all without Electron差 maana.

Each agent connects over its strongest native interface — stream‑json, JSON‑RPC, live events — and is normalized into one provider‑neutral model. Rewind means every prompt checkpoints your working tree under a hidden git ref, allowing you to roll back code and the provider conversation together, not just the chat log. Keyboard first: ⌘N starts a session, ⏎ queues a follow‑up while the agent works, ⌘⏎ steers it mid‑turn, Escape stops. Every control works without a mouse.

All data—projects, sessions, transcripts, and provider IDs—live locally on your disk. No account, no telemetry, no cloud between you and your agents. The app stays quietly current: signed, notarized, and auto‑updated with binary deltas via Sparkle.
