misata
Generate relational test data that satisfies what you declared, then get back a check that it did.
What it can do
- Generate From Story: Generate a complete relational synthetic dataset from a plain-English description. Misata's deterministic engine guarantees 100% foreign-key integrity and exact declared outcome c
- Generate From Schema: Generate synthetic data from a Misata dict schema. No API key required. Returns data for every table with an FK integrity proof.
- Design Schema: Design a relational schema from a plain-English description without generating data. Returns a Misata schema dict ready to pass to generate_from_schema. Requires a Groq, OpenAI, or Anth

Generate relational test data that satisfies what you declared, then get back a check that it did.
Describe the dataset in a sentence or hand over a schema. Misata builds every table in one pass, so foreign keys resolve, parent totals equal what their children actually sum to, and a column declared as qty * price holds on every row. Same schema and seed, same data, so a fixture you liked yesterday is still there tomorrow.
The division of labour is the point. Your agent designs the schema, which is what agents are genuinely good at. The engine handles the arithmetic, which is where generated data quietly goes wrong: line items that look perfect and don't add up, a summary figure that disagrees with the rows underneath it. generate_from_schema needs no API key and returns an integrity proof for every relationship.
Seven tools, including one that fills a real database from its own schema, parents before children, every key verified afterwards. It plans first and writes nothing until you confirm.
