Free, Production-Grade Databases. Get setup in minutes. Great for testing and development
Published: September 1, 2025
Neon: My top choice for AI apps. Database live in <1 sec. Straightforward API for creating / modifying databases and role.
Supabase: Auth integration.
Aiven: Most generous free tier (5GB) and supports both Postgres & MySQL.
I use these for creating a 'one-time-use' database for testing to live client projects.
