Datomiq
Datomiq is a free desktop client for PostgreSQL, MySQL and SQLite — grid editing, EXPLAIN plans, schema tools, ERD, import/export, the lot. Its built-in AI agent runs on the Claude or Codex subscription you already pay for, so there is no new AI bill.
The two ideas
- A serious client, free. The table-stakes features of a paid client are all here, at $0. Nothing in the client is gated behind a trial clock.
- Bring your own AI. The agent signs in with your existing Claude or Codex plan. Reads run automatically on a read-only path; writes always stop at an approval card showing the exact SQL.
Where teams come in
When a team outgrows sharing credentials in a vault, Datomiq adds Shared and Managed connections — brokered, audited access you grant instead of passwords you paste. Those are the paid tiers; see Getting started.
