Worktrunk, a free and open-source command-line tool, is designed to let developers run five to ten AI coding agents, such as Claude Code and Codex, in parallel without the agents overwriting one another's changes.

Worktrunk aims to let developers run 5–10 coding agents at once without file collisions
Worktrunk applies the ease of git branch switching to git worktrees, so each AI agent gets its own working directory inside the same repository. Its stated goal is to remove the manual setup that isolation has required.

GitHub stars, a measure of community interest rather than adoption or performance
Target scale: agents running at the same time
Each block is one agent running in its own worktree. Column height is drawn to scale.
Doubling the agent count doubles the number of isolated working directories to manage.
From shared checkout to isolated worktrees
The problem Worktrunk targets, and the isolation it provides.
1. Shared checkout
→
2. Conflicting edits
→
3. One worktree per agent
→
4. Isolated file changes
Caveats before adopting
Reliability and performance at scale are not yet independently verified.
No independent reviews, benchmarks, or detailed user feedback were available.
Compatibility with specific agent workflows remains unverified.
Git worktrees carry their own costs: disk usage, plus dependency and build state in each directory.
What works in its favor
Makes worktree isolation as simple as switching branches.
Targets a real problem as coding agents edit code autonomously.
Free, open-source, and built for the terminal and git.
What remains open
Whether adoption grows beyond community interest.
Whether it holds up at 5–10 concurrent agents.
Whether it fits managed platforms or stays a terminal-first tool.
