Teammates and agents work in one thread, and DeltaDB records every edit together with the conversation behind it on top of your existing git repository, so reviewers can see how code came to be and comment in context.

| ProEntry plan | $10 | per month |
Personal is free and works with your own API keys or external agents such as Claude Code. Pro costs $10 per month and adds Zed-hosted models with $5 of tokens included each month and usage-based billing beyond that. The account and credits are shared with the Zed editor.
Best for
Teams that want agent conversations, code changes and review in one shared place, especially those already using Zed or looking to replace pull-request-centred review with threads.
Not ideal for
Teams that need a stable, finished product or depend on GitHub pull request workflows and CI integrations, since Delta is in public beta and some capabilities are still on the roadmap.
A thoughtful take on collaborative agent coding that keeps the reasoning behind every change, worth trying for teams already comfortable with Zed, with the caveat that it is still a beta.
Delta entered public beta on September 16, 2026, after a private beta that started on August 12, 2026; Zed says it disabled pull requests on Delta's own repository and now builds Delta entirely within Delta. Pricing offers a free Personal plan and a $10 per month Pro plan shared with Zed.
