Parallax

Parallax is a macOS application that runs multiple coding agents side by side.

Parallax runs Claude Code, Codex, Cursor, Amp, Capy, Gemini CLI and OpenCode side by side on your Mac. The Captain keeps agents aligned with your instructions by splitting tasks, checking steps, pulling drifting agents back and returning pull requests. It features native code review that reviews the whole session against what you asked, using the Conifer router to pick reviewers from different labs. It also automatically switches between connected subscriptions when one hits its limit so work continues without losing progress. Users can sign up with GitHub to receive credit and free reviews, or run agents on the credit if they lack a Claude or ChatGPT plan.
