Worktrees isolate code. Not runtimes.

We just launched coasts.dev , our open source solution to "the worktree problem." The latest multi-agent parallel coding workflows lean heavily on git worktrees, a feature that was never intended for this use case. Worktrees create a git-linked copy of your code so multiple agents can work in isolation. The problem is that AGENTS NEED RUNTIMES. When agents are at their best, they get feedback on their work and keep making progress. They know when they've caused errors, they can run integration tests, they can access the browser. When your agent is working against a worktree, it's looking at a set of files and guessing, not verifying. There's a trend on social media where engineers are flexing setups where they're working on two or even three laptops at once. Companies are buying their engineers second machines, while 80-90% of the first machine sits idle. This is an infrastructure problem being solved with hardware. Coasts fixes this. Coasts are highly configurable containerized hosts
