Hey Dev community!
I'm a newcomer in a webdev area with my first product - DummyDatabase.com I've made it to solve a simple, yet annoying problem — generating realistic test datasets quickly, without writing scripts or juggling Excel files. Stack: Flask, Python, PostgreSQL, JavaScript, HTML & CSS, Bootstrap, Redis
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 Numbers, 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?
- What would you suggest to change or improve in a current setting?
- Would an API for data generation be useful for you?
