SynthForge IO was built to create realistic test data across different database platforms. I've always wanted something with diagramming and could be used for all the databases I use: Postgres, MySQL, MongoDB, and more. Now I can import my existing schemas, visually adjust the design, or describe with AI, then generate data to any NoSQL or SQL database. (MySQL, MongoDB, Postgres, DuckDB and more) It has the normal data generators you would expect, plus some fun custom ones like role-playing names and weapons. Completely free to use at https://synthforge.io Quick video intro at
Would love feedback! Especially on what field types or export formats are missing.
