Zed unveils Delta, a private-beta collaborative coding app for agents, code review, and context-rich development threads

Zed is introducing Delta, a multiplayer coding environment where developers and AI agents can collaborate, discuss work, and review code in one shared thread. Its DeltaDB system syncs conversations and worktrees in real time while preserving compatibility with existing git repositories and workflows.

Delta reflects a broader shift from IDEs as solo coding tools toward collaborative workspaces where agentic coding and code review happen continuously. By tying comments to evolving code rather than static commits, it aims to reduce context loss as AI-generated and human-written changes move through teams.
