Delta is a multiplayer environment for collaborative coding with AI agents that unifies conversations, code changes, and version control in shareable threads. It enables real-time teamwork with anchored comments and decisions, backed by DeltaDB, a version control system that tracks fine-grained changes rather than snapshots.
Anthropic launched Delta, a public beta multiplayer coding environment designed to replace pull requests by enabling real-time collaboration between developers and AI agents. Delta uses DeltaDB, which extends Git with delta-based versioning to preserve the evolution of code changes alongside agent and human context, allowing teammates to join threads and continue work without traditional commit-based workflows.
