Parallel Code

Parallel Code is a parallel AI coding workspace for dispatching coding agents in isolated branches. It is built around a review workflow in which agents run in separate worktrees, their diffs are checked, and selected changes are merged while the rest are discarded. That isolation is meant to keep agents from overwriting one another’s working copy during concurrent tasks.

The app creates a git branch and worktree automatically for each task. Users create a task, describe what they want built, pick an agent, and let it run in isolation. Supported agents listed on the page include Claude Code, Codex CLI, Gemini CLI, Copilot CLI, and Antigravity CLI, and it also says any CLI-based coding agent that works in a terminal can be used. Review happens through diffs and changed files, and merging back to main can be done from the sidebar with one click. The page also describes uses such as dividing a backlog among several agents, sending one agent after a flaky test while another builds a feature, and comparing two framings of the same prompt side by side.

Parallel Code runs as a native desktop app and is described as a standalone Electron app. It works with VS Code, Cursor, JetBrains, and Sublime, while the app itself manages the agents and worktrees. The page says it runs actual terminal CLIs inside the desktop app rather than a web abstraction. It is also described as keyboard-first, with shortcuts for every action, and as phone-ready for monitoring agent terminals over Wi‑Fi or Tailscale by scanning a QR code. Supported platforms listed on the page are macOS and Linux, with a macOS download available as a .dmg and Linux downloads available as .AppImage or .deb.

Parallel Code is free and open source under the MIT license, with no extra platform fee or subscription. It says user API keys stay with the user and are not proxied or collected.
