Harp

Run many Claude Code and Codex agents side by side, in one calm sidebar that tells you which one needs you.

Harp is an unofficial fork of the open-source Warp terminal.
It replaces the tab bar with a sidebar built for long-running coding agents and keeps the rest of
Warp as it is.

What it adds

      Agent states at a glance
      Each row shows whether its Claude Code or Codex session is working, waiting for you or
      done, with an unread mark until you look. A dot means background work is still running;
      a moon marks a tab you set aside. Cmd+R renames a tab.
      Groups that stay put
      Put tabs into named groups. With the tmux integration on, the group and the order are
      stored on the tmux sessions, so they survive a restart and other tmux clients see the
      same layout.

      Limit rings
      Two rings per provider in the footer: the 5 hour window and the weekly limit. Hover one
      for the numbers and reset times. Codex's come from its own session logs, Claude's from
      Claude Code's status line (see below). Harp fetches nothing and
      reads no credentials.
      Phone-friendly tmux
      Tabs attached to tmux follow their session: name, group, read and inactive flags.
      A session started elsewhere, for example from your phone over ssh, can ask for a tab
      with tmux set-option @warp_adopt 1.

Everything else is upstream Warp, including its AI and cloud features (agents, Warp Drive, session
sharing, login). They talk to Warp's servers exactly as upstream does; Harp adds no servers of its
own. Logging in through Harp is untested.
