About

stagewise is building the open-source agentic IDE: a developer workspace for creating and orchestrating coding agents, previewing running apps, and managing Git workflows. Developers can run agents in parallel, use their preferred models or existing coding subscriptions, and keep agents connected to browser/runtime context as well as the broader codebase, from APIs and tests to docs and deployment paths.
