Fanout: open-source tool tames parallel Claude Code and Codex sessions before merging
crumb_ona_breadstick · reddit · 2026-10-27
A Reddit developer open-sourced Fanout, a tool for managing parallel Claude Code / Codex sessions, tackling the pain of multiple agents finishing independently but breaking things when their branches merge.
Key features:
- Detects duplicate tasks across sessions
- Notifies agents about relevant changes committed by other sessions
- Checks overlapping Git worktree changes
- Tests combined branches before merging in its managed parallel workflow
Built on Node.js and Git, MIT-licensed, aimed at developers already running multiple AI coding sessions on one repo. The creator is looking for real-world testers.
