Zed Ships Delta: a Multiplayer Agent Coding App Built on DeltaDB, a Git Replacement That Keeps Every Operation Between Commits
On August 12 Zed opened private-beta invites for Delta, a standalone multiplayer app where humans and agents code in shared persistent threads, built on DeltaDB, a version control system Zed has been building for over a year that records a stream of fine-grained deltas with stable identities instead of Git's snapshots. Every code change is bidirectionally linked to the agent conversation that produced it, and Delta stays compatible with existing Git repos so teammates not using it still see a normal repository. It connects to third-party agent harnesses starting with Claude Code, so a terminal session syncs live into a Delta thread. The pitch is that Git's snapshot model permanently discards the multi-turn reasoning that now produces most code, which makes the PR the wrong review unit.
