What is the best free database for a web app?

Supabase is the best free database for beginners. It gives you a full Postgres database plus logins, file storage and an API in one dashboard, and AI coding tools know it well. Free projects pause after a week with no activity. Neon is a free serverless Postgres that sleeps when idle and wakes instantly. Cloudflare D1 is a free SQLite database for apps hosted on Cloudflare.
