Chronos DB

Name: Chronos DB
Author: Abhishek DG / 2090 (chronos.2090.tech)

Chronos DB is a Postgres-compatible database for AI agents: each agent gets an instant copy (“world”), rule-checked merges into production, and about an hour of history to read or undo.

Why it matters

For teams letting coding agents write to databases who need isolation and merge rules so risky deletes or schema changes wait for a human.

Highlights

Speaks the Postgres wire protocol (psql, Prisma, Drizzle, psycopg, pgvector); each agent works on an instant full copy while production stays untouched.
You set merge rules (row-change limits, delete limits, always-reviewed tables, schema changes); safe changes merge; violations wait for review.
Read any table as of a minute in the last hour and undo a merge row-by-row for about an hour after it lands.
MCP server with agent verbs; Chronos Gateway can sit in front of existing Postgres 12–18 (including Supabase/Neon). Self-host free under BUSL-1.1; cloud on a waitlist.

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Try it if: You let Claude Code, Cursor or other agents change Postgres data and want per-agent copies plus automatic merge rules.

Worth knowing: Benchmark and timing claims (e.g. ~2μs forks, BranchBench comparisons) are the maker’s. GitHub star count is still very low. Cloud not generally available yet.
