Waku drives the agent CLIs already on your machine — Amp, Claude Code, Codex, Cursor, OpenCode, Grok, Pi — and normalises their sessions into a single timeline. The detail that earns it: every prompt checkpoints your working tree under a hidden git ref, so rewinding rolls back the code and the conversation together instead of leaving you with an undone chat and a directory full of edits. Built on Rust and GPUI, the framework behind Zed.
