Hi - I built Harness [1] as a reaction to the closed source IDEs that keep popping up (Antigravity/Conductor/Cursor). I wanted something better than those that is also community supported.

Harness is an agent first IDE built around git worktrees. It's designed to make it easy to organize a bunch of Claude Code sessions for all the different projects you are tackling right now

It supports macOS and Linux. And experimentally it allows separating your frontend & backend so that the agent runtimes can live in a dev box while the UI can run on your laptop.

Let me know what you think
