Arbor

Native Rust and GPUI app for agentic coding with worktrees, terminals, and diffs

Aboutgithub.com

Arbor is a fully native app for agentic coding, built with Rust and GPUI. It manages repositories, issue-driven Git worktrees, embedded terminals, managed processes, diffs, pull request context, and coding agent activity. A shared daemon also powers its web UI, CLI, and MCP server. It uses the MIT license.

Install

brew install penso/tap/arbor

For an agent

Use it to run long agent sessions in worktrees with native performance. It expects a Nerd Font for its terminal, so install one first.

Why it is here. It is a native, open-source example of the worktree-per-task agent workflow.
