RESTful and GraphQL APIs are generated instantly from that database schema without extra coding. Authentication supports email, social providers and magic links with role-based access control, and apps can listen to database changes in real time. Files are kept in public and private storage buckets.
It is designed for web and mobile app developers, startups building MVPs and teams wanting to avoid managing backend infrastructure. The free plan includes a 500MB database, 1GB storage and basic authentication, the Pro plan costs $25/month with increased limits and email support, and enterprise pricing is custom. The main technical constraint is that it is limited to PostgreSQL database technology.
