Parallel Code review

Parallel Code is an Electron desktop app that runs several terminal coding agents side by side, each task on its own git branch and worktree. It is free under the MIT licence, copyright Johannes Millan, and you bring your own agent CLIs and logins. This write-up draws on the vendor's site and GitHub pages as read in November 2026; we did not run the app.

A board sorts tasks by what they need from you, and the diff viewer sends inline comments back to the agent. Built-in agents are Claude Code, Codex CLI, OpenCode, Copilot CLI and Antigravity CLI. An arena runs one prompt with two to four agents, and with a setting turned on, an agent can create tasks through MCP. Phone access uses a QR code over Wi-Fi or Tailscale, and the site says there is no Parallel Code server or account.

The target reader is a developer on macOS or Linux who runs several agent CLIs on one repository and reviews each branch before merging. There is no Windows build, and the site FAQ says so. Agents run on your own computer, not in the cloud. The site describes the project as mostly one maintainer. The docs mention a sideloaded Android APK, which we did not find among the releases.

Release v5.1.0 was published on 29 October 2026, and the repository showed 1,082 stars on 7 November 2026. Other worktree-based agent managers are Conductor and Claude Squad.

Parallel Code features

✓ documented · – absent or not in its feature list · ? not verified

Parallel Code strengths

  • MIT licence, no account and no vendor server; code goes only to the agent CLIs and models you choose
  • Mixes Claude Code, Codex CLI, OpenCode, Copilot CLI and Antigravity CLI on one board, plus custom terminal agents
  • Built-in diff viewer with inline comments sent back to the agent, guided change tours and an optional review by a separate model
  • Optional MCP-based task orchestration for agents, an arena that runs one prompt with two to four agents, and per-project Docker sandboxes

Parallel Code weak points

  • No Windows build; the site FAQ says there is none yet
  • Agents run on your own computer, so it does not cover agents that keep working in the cloud while the laptop is off (README)
  • The site describes it as mostly a one-maintainer project with a few outside contributors
  • Phone access needs the phone to reach the computer over Wi-Fi or Tailscale; notifications over HTTP need extra HTTPS setup such as Tailscale Serve

Who Parallel Code is for

best for
Developers on macOS or Linux who want to run several agent CLIs on one repository and review each branch before merging.
look elsewhere if
Windows users, or anyone who wants agents that run in the cloud independently of their own machine.
