{"id":17943,"library":"seedfast","title":"Seedfast CLI","description":"Seedfast CLI is an AI-powered command-line interface tool designed to generate realistic test data for PostgreSQL databases. Currently at version 2.3.0, it maintains a regular release cadence with frequent patch and minor updates, indicating active development. Its core functionality involves connecting to an external backend service that leverages AI to analyze a given PostgreSQL database schema, understanding intricate table relationships and constraints. Based on this analysis, it formulates an intelligent seeding plan. Key differentiators include its ability to produce contextually appropriate and realistic test data, a rich interactive terminal interface with real-time progress tracking, a multi-worker architecture for efficient concurrent execution, and secure OAuth-style device flow authentication with OS-level credential storage. It supports multiple installation methods, including npm, Homebrew, or direct binary download, and offers dedicated integration patterns for CI/CD environments.","status":"active","version":"2.3.0","language":"javascript","source_language":"en","source_url":"https://github.com/argon-it/seedfast-cli","tags":["javascript","postgresql,database,seeding,testing,ai"],"install":[{"cmd":"npm install seedfast","lang":"bash","label":"npm"},{"cmd":"yarn add seedfast","lang":"bash","label":"yarn"},{"cmd":"pnpm add seedfast","lang":"bash","label":"pnpm"}],"dependencies":[],"imports":[],"quickstart":{"code":"# 1.
