DummyDatabase.com: DATA GENERATION MADE SIMPLE

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

Dummy Database website

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?
