Waku: a native desktop app in Rust and GPUI that unifies multiple coding agent CLI sessions

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

Waku is a native macOS app that wraps coding agent CLIs like Claude Code and Gemini CLI into one GPU-accelerated window. Built with Rust and GPUI—the same framework behind Zed—it launches instantly and scrolls through years of transcripts smoothly. Every prompt checkpoints the working tree under a hidden git ref, so rolling back reverts both code and conversation. All data stays local: no account, no telemetry, no cloud. Only macOS is available now; the post doesn't give a timeline for Windows or Linux.

Why it matters: Show HN launch with a distinctive Rust + GPUI native stack and a real differentiator in conversation-aware checkpoints. But v0.1.0 just shipped — no user numbers, no comparison against existing workflows (tmux + git). Lands at the featured threshold of 72, not higher.
