parallel code - parallel ai coding agents in isolated worktrees

About Parallel Code

Free, open-source desktop app that dispatches AI coding agents in parallel, each in its own git worktree. It runs the real CLI agents you already trust (Claude Code, Codex, Gemini) side by side, then lets you review the diffs, merge the wins, and toss the rest.

Key Capabilities

Run multiple AI coding agents in parallel, each in an isolated git worktree

Bring your own agent: Claude Code, Codex, Gemini, Copilot, Antigravity

Built-in diff viewer with inline review comments before you merge

AI Arena races agents head-to-head on the same task

Monitor progress from your phone via QR code over Wi-Fi or Tailscale

Free and open source under the MIT license, no platform fee

Standout Features

Worktree Isolation

Every task gets its own git branch and worktree automatically, so parallel agents never step on each other.

AI Arena

Race agents head-to-head on the same task, then keep the result you like best.

Built-in Diff Review

Inspect every change in a diff viewer with inline comments before merging anything.

Phone Monitoring

Scan a QR code to watch your agents work from your phone over Wi-Fi or Tailscale.

Real CLI Agents

Runs the actual terminal CLIs you already trust: Claude Code, Codex, Gemini, Copilot, Antigravity.

Perfect for

Developers running Claude Code, Codex, or Gemini CLI
Solo indie hackers clearing parallel backlog items
Keyboard-first workflows
Racing agents head-to-head
macOS and Linux users
