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. Download for mac OS. Try the live demo. For Apple silicon and Intel Macs, signed and notarized. Open source.
How to get started: Start with 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.
Watch it work: 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. Side by side: 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.
Make it yours: 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. It keeps going: 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.
Install: Your agents, docked. The app for your Mac, and berthd on each box. Free and open source. Download for mac OS. On your box: curl -fs SL https://berthd.app/install | sh
