npx create-db: Instant Postgres for Your Coding Agent

create-db is a zero-install CLI that spins up a real Prisma Postgres database in seconds with a single command, no account required. Built for AI coding agents like Cursor and Claude Code, it solves the classic "mocks lie, Docker is heavy" problem by giving each task its own clean, ephemeral database that auto-deletes after 24 hours. A claim URL lets you promote it to a permanent instance if the work matters.
