Built for Developers, by Developers
SQL Syntax Native
Most generators fail at escaping single quotes (O'Reilly vs O''Reilly). MockBlast understands PostgreSQL, MySQL, and SQLite syntax natively, so your INSERT statements run on the first try.
Privacy First
Unlike Mockaroo or ChatGPT, we don't train AI models on your schema. Your table structure is parsed locally in your browser (or ephemeral server memory) and discarded instantly.
Simple, One-Time Pricing.
Stop paying monthly subscriptions for fake data.
Perfect for small prototypes and testing.
- 1500 row generation

Frequently Asked Questions
- Is this a subscription?
- No. You pay once, you own it forever. We hate subscriptions for simple tools too.
- Why lifetime only?
- We believe fake data generation shouldn't be a recurring expense. Pay once, use forever, and focus on building your projects instead of managing subscriptions.
- Does my data go to your server?
- We generate data on our own server and stream it to you. Once you receive it, you are the only one having it. We don't store your generated data.
- Do you save our schemas?
- It's your preference whether you want to save your schemas or not. You can choose to save them for quick access later, or keep them private.
- Do you support having teams for collaboration?
- Team collaboration features are coming on official launch.
- Can I use this for client work?
- Yes, the license covers commercial usage. You can use the generated data for any number of client projects.
- What databases are supported?
- Currently we support PostgreSQL, MySQL, SQLite, and generic JSON output. MongoDB support is coming on official launch.
