The Free Mockaroo Alternative: 10x More Rows (Local-First)
Stop hitting Mockaroo's 1,000 row limit. MockBlast gives you 10,000 rows for free—10x more than Mockaroo. Better SQL support and zero data leaks.
Why Developers Are Switching from Mockaroo
Mockaroo has been the go-to tool for generating mock data, but developers are hitting its limitations:
- •API Rate Limits: Mockaroo restricts free users to 1,000 rows per request and 200 requests per day. MockBlast gives you 10,000 rows for free—10x more than Mockaroo.
- •Data Privacy Concerns: Your database schemas are sent to Mockaroo's servers. For sensitive projects, this is a security risk.
- •Limited SQL Support: Mockaroo struggles with advanced PostgreSQL features like JSONB, arrays, and foreign key relationships.
- •Subscription Model: Mockaroo charges monthly/yearly subscriptions. MockBlast offers lifetime pricing—pay once, use forever.
