Baton is a desktop app for orchestrating multiple AI coding agents in parallel. Each agent runs in its own git-isolated workspace, with smart notification badges to flag which agents need attention. It supports Claude Code, Codex, OpenCode, and any terminal-based agent. Features include diff review, file browsing, codebase search, and a built-in MCP server that lets agents spawn new agents. Built by a developer who needed a single unified interface to manage multiple agents without constant window-switching.
