Show HN: I built a native app for coding agents with Rust and GPUI

Waku is a native desktop application built with Rust and GPUI that unifies multiple coding agents into a single interface, allowing users to manage sessions, transcripts, and checkpoints locally on their machine without cloud storage or telemetry. The app supports various agent CLIs through native protocols like JSON-RPC and stream-json, features keyboard-first controls, and enables users to rewind and roll back both code changes and agent conversations together using git checkpoints. It currently runs on macOS with plans for Windows and Linux support.
