Kero
A terminal for coding agents, on macOS, Windows and Linux.
Run Claude Code, Codex, a dev server or a test watcher each in its own session. Kero groups sessions by project in a sidebar that shows which are working, which need you and which are done.
- Sessions outlive the window. They run in
kerod, a small daemon, so quitting Kero leaves them running. Reopen it and every pane and its scrollback is back.
- Status at a glance. Each pane is working, waiting, idle, error or exited. ⌘ J jumps to the one that needs you, and Kero notifies you when an agent finishes, fails or is blocked.
- A CLI agents can drive.
kero starts sessions, splits panes, types into them, waits on them and reads their screens.
- Remote hosts. Run agents on a Linux box, a cloud VM, a Mac, a Windows PC or WSL and see them in the same sidebar, over SSH or Tailscale. They keep running when your laptop sleeps. See Remote Hosts.
- Ghostty under the hood. Terminals render with libghostty, so Ghostty themes, fonts and config keys just work.

See the docs for more.
Prior art
- Rex: Mitchell Hashimoto's terminal and multiplexer in one native app, with sessions that persist through a server and a scriptable CLI.
- Herdr: a terminal multiplexer for running many coding agents in one terminal, with agent status detection.
