handup

handup is an approval inbox for AI coding agents. When an agent wants to do something consequential, like run a database migration, push a release or send an email, it sends a request with the real thing attached: the command, the diff, the file, the email draft or an image. You approve it, or deny it with feedback such as "use staging instead", from `handup inbox` in the terminal, the desktop app or the Android app. A denial reaches the agent as a normal answer, so it changes course instead of retrying. `handup setup` connects the agents it finds: Claude Code and Codex get a permission hook plus MCP; Cursor, omp, Gemini CLI, opencode and other MCP clients use `handup mcp`; scripts and CI use `handup ask --wait`. Requests and decisions stay in a daemon on your own computer, with no handup account. On the desktop you can run an approved command and return its exit code to the agent. handup is a review tool, not a sandbox. Runs on Linux, macOS and Windows (beta) with an Android companion. 14 days free with every feature and no signup, then $30 one-time per person, released updates included, 30-day refunds.
