Berth

Berth is an open-source desktop application that runs coding agents on remote development boxes.

Berth is an open-source desktop app and daemon designed to run coding agents like Claude Code and Codex on your own development boxes. The application allows you to work with these agents from your laptop, creating a worktree on your chosen box with its own dev server tab when you start a task. Commands and reads fold into a single line while edits arrive as diffs, and you can answer agent prompts in place. The system supports comparing two worktrees in mirrored lanes, including their chats, diffs, and terminals. It also features customizable themes, chat backgrounds, and adjustable text sizes. It is built for developers who need persistent coding agents operating outside their local machine.
