- Proxy support with automatic timezone and language matching
- Hosted cloud browsers billed per GB with residential IPs
- Docker and CDP endpoint support
- MCP server for AI agents including Claude, Cursor and Cline
- WebRTC proxy IP matching
| - Reads live database schema to generate coherent test data automatically
- Generates realistic data at scale from hundreds to tens of millions of rows
- Maintains foreign key integrity and constraint satisfaction
- Generates localized data with culturally appropriate names and formats
- Works as CLI, MCP server for AI editors, and CI/CD pipeline step
- Handles complex schemas with composite keys and multi-level dependencies
- Plan preview shows exactly what will be seeded before writing any rows
- Never requires access to production databases
- Generates data with realistic distributions across columns and tables

|---|
| What makes it different | - Fingerprints set in Chromium engine rather than injected into pages
- Fully open-source and reproducible from public source code
- Same engine available self-hosted, containerized, or hosted in cloud
- Drop-in replacement for Playwright and Puppeteer with minimal code changes
- Cross-realm consistency with agreement between main thread, workers and iframes
| - No production data exposure: generates all test data from schema alone, eliminating privacy and compliance risks
- Schema-aware generation creates coherent, relational data without manual seed scripts
- Integrated with AI editors through MCP server for seamless developer workflow
- Realistic data that surfaces real bugs, not random placeholder values
- Works at any scale with consistent data integrity from dozens to tens of millions of rows
