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.
For Apple silicon and Intel Macs, signed and notarized. Open source. How to get started
One line. A worktree, a box, an agent. #
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.
Every step, as it happens. #
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. One view. #
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.
Your themes. Your harbour. #
Berth's own themes and nineteen ports of favourites, Dracula to Rosé Pine, carried into the terminal and every diff. A chat background of your own, and ⌘+ when you want it larger.
Close the laptop. They keep going. #
The agents run on your boxes, not on your laptop. Close it and they keep working; open it in the morning and what they did is there.
