Zed founder Nathan Sobo has a blunt take: software is made between commits, and git throws all of that away. His answer is DeltaDB, a new version control system that hit 335 points and 175 comments on HackerNews — because it names a real pain every coding-agent user has felt.

What DeltaDB actually does

Git snapshots your code at commit time. DeltaDB records every operation in between and gives each one a stable identity. Crucially, every line links back to the agent conversation that produced it — “why was this written” drops from commit-message granularity to conversation granularity. Built on CRDTs, it virtualizes the worktree: any point in history is a valid branch point, including mid-run while an agent is still working. Teammates can join live, talk to the same agent, and skip the commit-push loop entirely.

Why it matters

When agents write most of your code, git blame says “the agent did it” — useless. DeltaDB makes provenance queryable: agents can read the full edit history and ask prior agents about design intent. It complements git rather than replacing it. Early access is open via waitlist now.
