Parallel Code vs Conductor

If you’ve outgrown running one AI coding agent at a time, you’ve probably found both of these tools. Parallel Code and Conductor solve the same core problem: dispatch several coding agents at once, give each its own isolated copy of the repo via a git worktree, then review the diffs and merge the good ones. The difference is in where they run, what they cost you in lock-in, and which agents they drive.

Here’s the honest breakdown.

What they have in common

Both are free desktop apps that run entirely on your machine using your own API keys or agent subscriptions — nothing is proxied through a third-party cloud. Both create a dedicated git worktree per task so agents never collide on the same files, and both give you a diff-first review surface to approve or discard each agent’s work. If your whole goal is “run three or four agents in parallel on a Mac and review the results,” either tool will do that well.

Where Parallel Code differs

It runs on Linux, not just macOS. Conductor is Mac-only. Parallel Code ships native Linux builds (.AppImage and .deb) alongside its macOS build, so if any part of your work happens on Linux — a workstation, a remote dev box — it’s a first-class target, not an afterthought.

It’s open source. Parallel Code is MIT licensed. You can read exactly how it manages worktrees and spawns agents, fork it, self-build, or send a PR. Conductor is a free download but its source isn’t public.

It drives Gemini CLI and Copilot CLI too. Both tools support Claude Code and Codex. Parallel Code adds Gemini CLI, Copilot CLI, and Antigravity CLI; Conductor instead adds Cursor’s agent. So the right answer here depends on which agents you actually use — match the tool to your lineup.

You can watch progress from your phone. Scan a QR code and monitor long-running agents from your phone — over Wi-Fi or Tailscale — while you step away from the desk. Conductor has no equivalent.

Both can also point several agents at the same task to compare approaches: Parallel Code brands this as Arena mode (race agents head-to-head and keep the winner), while Conductor does it through a shared workspace. Call it a wash.

Where Conductor is strong

Credit where it’s due: Conductor is a polished, focused Mac app from Melty Labs (a Y Combinator team), with automatic git-worktree management and a clean review-and-merge flow. If you live entirely in macOS, it’s a strong, well-maintained choice. And if Cursor’s agent is central to your workflow, Conductor supports it directly while Parallel Code does not.

When to use each

Choose Conductor if you work exclusively on a Mac, want the most polished Mac app, and your agents are Claude Code, Codex, or Cursor.

Choose Parallel Code if you work on Linux (even sometimes), prefer open source you can inspect and modify, or want Gemini CLI, Copilot CLI, or Antigravity CLI in the mix.

Both are free, so the lowest-risk move is to try whichever matches your platform and agent lineup — and for most people that single fact decides it.
