Stoneforge vs Vibe Kanban

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

Vibe Kanban

A practical way to run several coding agents side by side without losing track of which branch is doing what, as long as you accept that it is now maintained by volunteers rather than a funded team. It suits developers who already use command-line agents and want a board and review layer on top.

Pros

• +Works with ten or more coding agents, so you are not locked to one
• +Each task gets its own git worktree, which keeps parallel agents from colliding
• +Inline diff comments feed straight back to the agent
• +Open source under Apache-2.0 and runs locally with one command

Cons

• −Hosted team features such as shared issues and organisations were removed after the shutdown
• −Future development depends on community maintainers and no published roadmap was confirmed
• −Needs separate, usually paid, accounts for the underlying coding agents
