Zed is building DeltaDB, a version control system that records every edit as a discrete, addressable delta instead of relying on commits. By linking each operation to its generating conversation, it lets humans and agents collaborate in real time on a shared worktree without waiting for snapshots or pull requests. Early beta access opens in a few weeks.

• DeltaDB replaces Git commits with a continuous stream of individually addressable edit operations, each with a stable ID.
• Messages and the edits they spawn are stored together, so comments anchor to deltas rather than line numbers and never drift when code changes.
• Conflict-free replicated worktrees let multiple humans and AI agents edit the same real on-disk files simultaneously, skipping pull-request workflows.
• Agents can trace why code exists by pulling up past conversations and even pinging other agents that previously touched the code.
