What changed
Delta is a separate app built on Zed’s DeltaDB that runs alongside Git. Instead of pull requests, teammates join agent threads, see the same worktrees and review changes in subthreads, with commits still serving as checkpoints. It runs on macOS, Linux, Windows and the browser, is free during the public beta, and Zed plans paid plans later while promising a free tier.
Who it affects
Teams that want a different review flow from pull requests for agent-written code.
What to do
Try it on a side repository first, and budget for paid plans later since pricing isn’t announced.
