👍 Good boy
+Provisions a real PostgreSQL database with full SQL access and Row Level Security.
+Generates instant RESTful and GraphQL APIs directly from your database schema without writing backend boilerplate.
+Handles authentication out of the box with social logins, magic links, and phone verification.
+Free tier includes two active databases, 50,000 active auth users, and 1GB file storage with no credit card required.
👎 Watch out
−Free tier databases pause after 7 days of inactivity and require manual dashboard resumption.
−Dedicated 500 MB storage cap requires upgrading to the $25/month Pro plan for scaling datasets.
−Limits accounts to two active free projects at any given time.
−Point-in-time database backups require upgrading to a paid plan.
The catch
Free projects pause after 7 consecutive days without API activity; reviving them takes a single click in the dashboard.
