MockBlast – Instantly generate over 1 million rows of SQL and MongoDB data

Summary: MockBlast generates millions of rows of mock data for PostgreSQL, MySQL, MongoDB, and SQLite by parsing raw CREATE TABLE schemas to auto-detect data types and maintain referential integrity. It uses streaming technology to deliver large datasets instantly and produces valid Bcrypt password hashes for testing authentication.

What it does

MockBlast imports raw SQL schemas to detect types like UUID, JSONB, and Boolean, then generates data while preserving foreign key relationships by caching parent IDs. It streams over one million rows directly to the browser without memory issues and supports native formats for multiple databases.

Who it's for

It is designed for developers and testers needing large-scale, realistic mock data for database performance testing and development without manual scripting.

Why it matters

It solves the limitations of existing tools by enabling fast, large-volume data generation with relational integrity and secure password hashes, removing row limits and manual data preparation.
