Harp

About

Harp is an unofficial fork of Warp that replaces the tab bar with a sidebar built for long-running coding agents. Every row says whether its Claude Code or Codex session is working, waiting for you or done, with an unread mark until you look, and tabs can sit in named groups that the tmux integration keeps across restarts. The footer carries a usage ring per provider, read from a local JSON file that another tool of your choice keeps current, so Harp never fetches those numbers itself. Everything else is upstream Warp: its terminal, its AI and cloud features, and its servers. Harp ships as its own app with its own bundle id and settings folder, so it runs beside Warp without sharing anything.
