A curated list of free PostgreSQL as a Service (PaaS) providers. Ideal for hobby projects, prototypes, learning, and experiments.
PostgreSQL is a powerful open-source relational database — but running it in the cloud can cost money.
Luckily, several cloud providers offer free-tier PostgreSQL services.
This repo helps developers discover and compare these options in one place.
To be included in this list, a PostgreSQL provider must meet all of the following:
- Free registration and no credit card required.
- No time limits on usage of the free tier — i.e., you can run your DB 24/7 without auto-deletion after a fixed trial period.
