Run 10 AI coding agents at once. Ship in an afternoon what used to take a week.
Parallel Code runs your agents in parallel, each in its own isolated git worktree. No conflicts, no juggling terminals. Review diffs, compare outcomes, keep the best result.
Your agents run as real terminal CLIs - same behavior, same config, nothing changes. Works with Claude Code, Codex CLI, Gemini CLI, or any CLI-based agent. Monitor everything from your phone. Free, open source, MIT licensed.
Parallel Code
Why I built Parallel Code
I've been maintaining an open source productivity app (Super Productivity) for 9 years and working as a programmer for much longer than that. When AI coding agents came along, they changed how I work - but the other tools and habits I grow comfortable with over the years, weren't a good fit anymore.
One agent works on a feature. I wait, get distracted, start something else. Finally, I come back, review, start the next one. Wait again. I had a backlog of ideas and the tools to build them, but things got messy. I was doing a lot, but I felt like I'd lost control compared to how I used to code.
I tried the obvious fixes. Multiple terminal windows were my new go-to solution, but got chaotic fast - which terminal was working on what? Tmux helped organize it, but I was still cycling through panes, switching tools for reviewing diffs and history, losing track of context, and dealing with merge conflicts when agents touched the same files.
So I built Parallel Code to fix this for myself.
The core idea: every task gets its own git branch and worktree automatically. Agents work in complete isolation - they can't conflict. I kick off 5, 8, 10 at a time, watch them all in a tiled view, and review diffs as they finish.
One design decision I'm particularly proud of: it runs your real terminal CLIs. Claude Code, Codex CLI, Gemini CLI - whatever you use today works exactly the same inside Parallel Code. Same behavior, same config, nothing changes. I didn't want to build another wrapper or chat UI. If you don't like the app, go back to raw terminals. Zero switching cost.
Some things I added along the way also turned out very useful:
- Phone monitoring - Scan a QR code, watch all your agent terminals from your phone. Sure there are other ways to do this, but this is really comfortable.
- Keyboard-first design - 40+ shortcuts. When you're managing 10 agents, reaching for the mouse is too slow. Best part is to navigate panes with just Alt+Arrow-keys.
- Built-in diff review and merge - The merge step is where quality happens. So having a quick way to do a code review is very useuful.
Parallel Code is free, open source (MIT), and always will be. No subscriptions, no platform fees, no telemetry. Your API keys stay on your machine.
I built this because I needed it. I'm sharing it because I think other developers - especially solo devs and indie hackers - hit the same problems I did. If you're running AI coding agents one at a time and don't have your tools setup in an optimal way, you're leaving a lot on the table.
macOS and Linux. Windows is on the roadmap.
Happy to answer any questions about the tool, the technical decisions, or why I chose to make it free.

The automatic git branching is a solid idea, but how do you handle potential merge conflicts when multiple AIs are working on the same codebase?

@trydoff I just tell AI to rebase on master/main (there is also a button for it in the merge dialog). It usually autofixes any merge conflicts very well.
