About
SeedBase generates realistic, foreign-key-consistent test data from your database schema. Point it at a SQL dump, Django models, or a Prisma schema and get a whole populated database that looks like production, not lorem ipsum or "Premium Widget 1".
Every foreign key resolves, order totals match their line items, names match emails, and distributions are realistic so pagination and N+1 bugs actually surface. Multi-database (Postgres, MySQL, MariaDB, SQLite, SQL Server), deterministic per seed for reproducible CI, EU-hosted, free tier.
It meets you where you work: VS Code and JetBrains plugins generate data right in your IDE, a CLI and Python/Node/PHP SDKs wire it into CI, and an MCP server lets AI agents (Claude, Cursor) generate test data for you. Test-data fixtures for pytest, Symfony, Laravel and Prisma drop a populated database into your tests. You can even serve a generation as a live read-only REST API (a mock backend) without writing one.
There is a login-free sandbox too: paste a schema and see the output in your browser.
