Berth runs Claude Code, Codex and other coding agents on your own dev boxes. Work with them from your laptop; close it, and they keep going.

Press ⌘N and say what you want. Berth makes a worktree on the box you choose and starts Claude Code, Codex or another agent in it, with its dev server in a tab of its own.

Commands and reads fold into a line, and edits arrive as diffs. When Claude asks, you answer in place; what it publishes is one click away.

Two worktrees share the tab strip as groups, each in its own colour, and split into one tab. Compare puts them in mirrored lanes: their chats, their diffs, their terminals.
