Replacing Pull Requests with Delta

We are excited to announce the public release of Delta, a collaborative coding environment designed for agents and reviewers. Delta's introduction addresses the need for updated collaborative tools as coding has evolved with the help of agents. The launch marks a significant milestone, as we have now entirely transitioned our work on Delta within the Delta environment, eschewing pull requests altogether.

Delta deviates from traditional workflows by eliminating the requirement to commit and push code for collaboration. Collaborators can directly join conversations with agents, with all team members seeing the same worktrees and being able to work on them from their own machines. Once someone joins the thread, they can continue working with the agents from where you left off, even if you're logged out.

Anyone can now download Delta for macOS, Linux, or Windows, enjoy web usage without installation, and stay updated on threads via a mobile browser. With the rise of agents generating substantial code, traditional diffs have become cumbersome. Delta threads offer a solution to this issue, allowing smaller diffs to provide sufficient context for review without losing the necessary background information.

Reviewers can follow the changes made through a branch, guided by the original agent's context, within their own isolated worktree.

DeltaDB, the foundation of Delta, extends Git's content-based versioning with incrementally recorded edits between commits. These deltas, alongside human and agent messages, preserve the evolution of the code throughout a thread. Commits remain as checkpoints for pulling, building, and pushing code, while DeltaDB retains the work between those checkpoints.

Currently, Delta is available for free during the public beta phase. Paid plans targeting individuals and teams will be introduced in the future. Delta has already become the team's daily driver, with 33 team members having landed 570 changes to the main branch since the pull requests were disabled.

For further information, you can try Delta with Zed on macOS, Windows, or Linux. We encourage you to share your feedback as we continue to develop Delta's capabilities and explore potential future integrations, such as CI-style verification directly within the thread. Thank you for your feedback and support as we strive to shape the future of software development.
