A quick demo of how easily Seedfast seeds your database.
Dev's shortcut to data
Here's what sets our seeding apart
Smart AI Seeding
Seedfast understands your schema the way a developer would. It reads relationships and triggers, then builds coherent, lifelike data that fits your models perfectly.
Built for popular DBs
Built around PostgreSQL, it understands how your schema works and fills your tables with data that fits naturally. Complex relations and triggers stay fully intact.
Zero scripts to maintain
No boilerplate, no fragile files to update after every migration. One CLI command replaces hours of setup and keeps your database always ready to use.
Time and cost efficiency
Traditional AI seeding burns tokens and time. Seedfast does the same job in minutes and at a fraction of the cost, even on large and complex databases.
Developer-first design
Built to adapt, not configure. Seedfast understands your environment automatically, generates consistent data, and never asks you to change your workflow.
Reliable, consistent data
Your datasets stay structured and fully interconnected. No mismatched relations, no random noise – just clean, realistic, production-like data every time.
“Seedfast literally saved me hours of setup time. I just ran one command, went for coffee, came back to a perfectly seeded database.”

Check out answers to the most frequently asked questions.
Seedfast currently supports PostgreSQL, with more database integrations (like MySQL, Oracle, and SQLite) coming soon.
Yes. That's where it performs best – handling triggers, nested relations, and multi-level dependencies with ease.
Seedfast can generate millions of records for your database, but be careful with the load, as not every database may be ready for this.
Most databases are filled within two minutes, even if they contain complex relation structure, constraints and triggers. Much faster than writing seeding scripts or filling data manually.
Yes, but Seedfast truly shines in development and staging environments, where quick and realistic data is key.
Pricing depends on the number of tables in your database. Each plan includes full AI seeding features with limits designed for different database sizes. You can change your plan anytime as your project grows.
