MockBlast

I built this because I hated the 1,000 row limit on other tools. Hi Hunters! 👋 I’m a developer who got tired of hitting paywalls just to test my database performance. Existing tools like Mockaroo are great, but the 1,000-row free limit wasn't enough for real load testing, and writing Python Faker scripts for every new project was a waste of time. So I built MockBlast. It’s a local-first data generator designed to be faster, more private, and more generous than the alternatives. The Killer Features: - Smart Schema Import: Paste your raw CREATE TABLE SQL. We use a regex engine to auto-detect types (UUIDs, JSONB, Booleans, Timestamps) so you don't have to map fields manually. - Relational Integrity: It handles Foreign Keys. It generates the parent table first, caches the IDs, and ensures your child tables reference real data. - 1 Million Rows via Streaming: We use Node.js streams to pipe data directly to your browser. No timeouts, no crashing your RAM. - Database Native: Supports PostgreSQL, MySQL, SQLite, and MongoDB (with ObjectId and ISODate wrappers). - Secure: It generates valid Bcrypt password hashes so you can actually log in to your generated accounts. The Deal: The free tier gives you 10,000 rows per file (10x the industry standard). To celebrate the launch, the users who sign up before 31st of January get a Lifetime Pro Account (Unlimited generations) for free. I’d love to hear your feedback specifically if the SQL parser handles your edge-case schemas correctly. Let me know what you think! 👇
