Hey Product Hunt! I built DummyDatabase.com to solve a simple, yet annoying problem — generating realistic test datasets quickly, without writing scripts or juggling Excel files. It’s designed for: - Developers needing dummy databases for prototyping & testing. - Analysts and BI specialists preparing demo dashboards. - QA engineers creating data scenarios for testing. - SQL learners who want practice datasets on demand. What makes it special? - Create from simple tables to full relational databases with PK/FK. - 35+ data types including JSON, Dates, Names, Booleans, etc. - Unique Event Sequences — simulate user actions and workflows. - Advanced data controls — outliers, nulls, repeats, distributions. - ERD visualization to map relationships. - Built-in PostgreSQL editor to query generated data. - Export as CSV, XLSX, SQL DDL, or full ZIP. - Free up to 10,000 records per table for registered users — no paywalls or limits. This is still an evolving product, and I’d love your feedback! - What features would you like to see next? - Would an API for data generation be useful for you? Thanks so much for checking it out!
