An assistant on your Mac that uses your tools, keeps working, and shows you what it did.
Ask it in the app's own Chat, email it, or drive it from the built-in terminal. It reads and acts inside the browser tab you are actually looking at, your Gmail, Calendar and Drive, and it works a durable queue that survives a restart. You bring the intelligence: Buster Claw has no built-in LLM and needs no API keys, and runs Claude Code, Codex, or OpenCode under the agent subscription you already pay for. Under the hood it is a Phoenix/LiveView application wrapped in a Tauri desktop shell.
Work lands in a durable Dispatch queue that Buster Claw projects to workspace markdown; the agent pulls items, does the work, and writes results back through the ./buster-claw CLI. The desktop UI gives you the command surface, the Sentinel audit feed, and the results.
Agentic command surface with 215 commands across CLI and HTTP API. A real browser the agent can drive — acting in your visible tab — plus SSRF-guarded fetch, Google Workspace sync and actions, GitHub integration, and a read-only SEC EDGAR and Finnhub finance surface. Dispatch pull-queue for terminal-driven work. In-app terminal with a real PTY. Orchestration shifts with a supervised Elixir janitor, a run cap, and a Stand down button in the dock that stops new work at once. BusterPhone answering machine: it answers, records, transcribes and files a voicemail, and archives inbound SMS. It sends nothing — no outbound texts, no outbound calls. Workspace library for markdown documents and artifacts. Sentinel security layer with an audit trail and redaction. Refusals are visible, not yet approvable.
Tauri v2 desktop shell, Elixir/Erlang backend, Phoenix LiveView web framework, SQLite via Ecto, PTY terminal via Tauri Rust shell, native-webview agent browser, Twilio and Supabase Edge Functions telephony relay, WebGPU WGSL backgrounds, Tailwind CSS.
Buster Claw is source-available, not open source. The app is a free download for macOS and may be used for anything, including commercial work — there is no license to buy and no account to create. The source is readable so the runtime can be audited rather than trusted on faith. Redistribution is not granted: you may not resell Buster Claw, repackage it, or ship a competing build from its source. The name, wordmark, and logo are reserved.
