GenerateData.com Alternative: Faster UI & Native SQL Support
MockBlast replaces GenerateData.com with a modern interface, faster generation, and better SQL support for Postgres and MySQL.
Why Developers Are Leaving GenerateData.com
GenerateData.com was one of the first online mock data generators, but it hasn't kept up with modern development needs:
- •Slow Performance: GenerateData.com processes everything client-side, making it painfully slow for large datasets (10,000+ rows).
- •Outdated UI: The interface feels clunky and dated. Adding fields and configuring options is tedious compared to modern tools.
- •Limited SQL Support: GenerateData.com struggles with modern SQL features like JSONB, foreign keys, and database-specific data types.
- •No Streaming: You have to wait for the entire dataset to generate before downloading. MockBlast streams data as it's generated.
MockBlast: The Modern Replacement
MockBlast was built from the ground up with performance and developer experience in mind:
⚡ Server-Side Streaming
Generate 1 million rows in seconds. MockBlast streams data as it's generated, so you can start downloading immediately instead of waiting for the entire dataset.
🎨 Modern, Intuitive UI
Built with React and Tailwind CSS, MockBlast's interface is fast, responsive, and easy to use. Add fields, configure types, and generate data in seconds.
🗄️ Native SQL Support
Full support for PostgreSQL JSONB, MySQL datetime formats, foreign keys, unique constraints, and more. Import your CREATE TABLE statements directly.
🔒 Local-First Privacy
Your schemas are parsed locally in your browser. Only generated data is streamed from our servers—your database structure never leaves your device.
Performance Comparison
Generating 100,000 rows with 10 fields:
MockBlast is 15x faster thanks to server-side streaming and optimized generation algorithms.

Frequently Asked Questions
- How is MockBlast faster than GenerateData.com?
- MockBlast uses server-side streaming to generate and deliver data instantly, even for millions of rows. GenerateData.com processes everything client-side, which slows down significantly with large datasets. MockBlast's modern React interface also feels more responsive.
- Does MockBlast support the same data types as GenerateData.com?
- Yes, and more. MockBlast supports all standard data types (names, emails, addresses, dates, etc.) plus advanced features like PostgreSQL JSONB, MySQL datetime formats, foreign keys, and unique constraints that GenerateData.com struggles with.
- Can I import my GenerateData.com templates?
- If you have SQL CREATE TABLE statements, yes! MockBlast's SQL import feature can parse your existing schemas. For GenerateData.com's JSON templates, you'll need to recreate them in MockBlast's visual schema builder, which is faster and more intuitive.
- Is MockBlast free like GenerateData.com?
- MockBlast is currently free during beta. After launch, we'll offer lifetime pricing (pay once, own forever) instead of subscriptions. GenerateData.com is free but limited and slower.
- Does MockBlast work offline like GenerateData.com?
- MockBlast processes schemas locally in your browser (local-first), but data generation happens server-side for speed and scale. This gives you the privacy of local processing with the performance of server-side generation.
