Stoneforge
Stoneforge fits developers who already use coding agents and want several working at once without merge chaos. The worktree-per-worker model and the automatic merge review do the heavy lifting. It is new, from a very small team, so it suits experimenters more than organisations that need vendor support.
Pros
- Each worker has its own git worktree, which avoids most merge conflicts
- Dependency-aware dispatch stops two agents taking the same task
- Works with Claude Code, Codex and OpenCode and syncs with GitHub, Linear and Notion
- Free under the Apache-2.0 licence
Cons
- Created in early 2026, so the track record is short
- Runs locally and has no hosted option
- Agent usage costs from the connected providers still add up
