Proliferate
An open IDE for running coding agents in parallel
#3 of the day · 17 Sep 2026
Proliferate is an editor built around running several coding agents at once — Claude Code, Codex, OpenCode and others — locally or in the cloud, with the sequences you repeat saved as workflows. Open source and self-hostable.

I now keep three terminals open with a different agent in each and no idea which one is ahead. That is not a workflow, it is a habit I have not examined.
This is the first tool I have tried that treats running several as the normal case rather than an accident. Being harness-agnostic matters more than it sounds: nobody wants to bet their editor on which agent wins.
