Documentation
Budi is an open-source, local-first cost tracker for AI coding agents. It tails the transcript files your tools already write to disk — nothing in your network path.
What budi does
After a single install command, three things run on your machine: a small Rust daemon that tails transcripts, a status bar in your editor, and a CLI for repo / branch / ticket attribution. Budi tracks Claude Code, Codex CLI, Copilot CLI, Cursor, and Copilot Chat (VS Code) today — with more agents coming.
- Multi-agent — one daemon tracks all your AI coding tools at once.
- Real attribution — cost is attributed per repo, branch, and ticket.
- Privacy-first — prompts, code, and responses never leave your machine.
- Online dashboard — opt-in, syncs aggregates only.
