About Harness Terminal
Harness is a native terminal for the Mac built around the idea of keeping your work running. Sessions persist after you close the app, so long running tasks and coding agents carry on and you can reopen to the same state. Saved workspaces let you reuse a layout of tabs and splits, and a cross session search helps you find output and insert file paths without hunting through scrollback.
It is aimed at developers who run several coding agents or work across machines. Agent activity and notifications show which pane needs attention, with a shortcut to jump straight to it, and the product lists 23 agent identities including Claude Code, Codex and Cursor. Remote work uses the SSH setup you already have: run the daemon and command line tool on a Mac or Linux server and connect from the Mac app. A built in command line tool opens splits, runs tasks and captures output from scripts.
Four interface modes range from plain tabs and splits to a keyboard first multiplexer with a command prefix, copy mode and paste buffers. The app is written in Swift and Metal, ships with 514 built in themes, and requires Apple silicon and macOS 15 or later. The current release shown is 2.0.1.
The site states that Harness is free and open source. No paid tier is mentioned.
