cmux, a free, open-source macOS terminal (built on Mitchell Hashimoto's open-source terminal engine, Ghostty) for running multiple AI coding agents like Claude Code and Codex in parallel, from YC S24 startup Manaflow.

~344,000 monthly visits (+5.7% over the last 3 months) as of July 2026, and a GitHub repo already screen-recorded by outside creators past 11,000 stars.
