Neon is a serverless Postgres platform built around instant database branching (creating isolated database copies for each dev/preview environment) — popular with teams using Vercel and other preview-deployment workflows who want a database that scales to zero and integrates with CI/CD branching. Our engine detects Neon through 1 script pattern and 2 HTML patterns tied to its connection and client-tooling conventions, which are lighter than front-end-facing products since Neon is primarily a backend database service with limited client-side footprint.
