Seedfast CLI

2.4.0 verified Fri May 01 auth: no javascript

Seedfast is an AI-powered PostgreSQL database seeding tool (v2.4.0) that generates realistic test data by analyzing your database schema. It uses an OAuth-style device flow for authentication and provides a rich terminal UI with real-time progress tracking. Key differentiators include AI-driven schema analysis to produce contextually appropriate data respecting foreign keys and constraints, concurrent multi-worker data generation for performance, and support for both interactive and CI/CD usage via API keys. The package is distributed as a CLI binary via npm (global install or npx), Homebrew, or direct download.
