# Berth — coding agents on your own boxes Source: [https://berthd.app/](https://berthd.app/) ## Agents that keep working when your laptop sleeps\. 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 macOS](https://github.com/sean-brydon/berthd/releases/latest/download/Berth-macos-universal.dmg)[Try the live demo](https://berthd.app/demo/) For Apple silicon and Intel Macs, signed and notarized\. Open source\.[How to get started](https://docs.berthd.app/getting-started/install) Start ## 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\. devl · 2 agents workinggpu · 1 agent working
