dominikmartn/harp is an unofficial Warp fork written in Rust that reshapes the macOS terminal to manage several coding agent sessions in one place. It shows Claude Code and Codex sessions side by side and displays in a vertical sidebar which session is currently waiting on you. The latest public release is v0.1.1, and the installer can be downloaded from the releases or built directly with the Rust toolchain named in the README.
Running Claude Code and Codex agents side by side makes it hard to see at a glance whether each session is working or waiting for input. Harp assumes a situation where multiple long coding agent sessions run back to back, and focuses on collecting that state into a vertical sidebar. An optional feature synchronizes the names and order of tab groups with terminal multiplexer tmux sessions, and a separate feature surfaces the usage quota from a JSON file that the tool updates. The README states that it is an unofficial branch of open-source Warp and does not add its own server. The language is Rust and the license is AGPL-3.0.
That said, the public description alone offers no performance comparisons or benchmark figures, and what v0.1.1 changed is also not stated. No independent test results or user feedback are available within the public scope. The repository was created on October 20, 2026, and has 102 stars, reflecting its nature as an unofficial Warp branch with no server of its own attached. Until more material accumulates, it is better regarded as a tool worth trying for teams running several agents at once.
