What they do

Problem

Developers lack an integrated workspace to reliably create, orchestrate, and manage multiple coding agents alongside live app context and Git workflows.

Solution

stagewise provides an open-source agentic IDE that lets developers run parallel coding agents using preferred models while staying connected to runtime/browser context, the codebase, and Git processes.

Who it's for

Software developers and engineering teams building and maintaining applications.
