Amazon Cognito and Supabase are both robust user authentication solutions, but they have different strengths. Amazon Cognito integrates well with other AWS services and offers a generous free tier with 50,000 monthly active users (MAUs) and competitive pricing as you scale. However, it has been criticized for confusing documentation and being difficult to set up. Supabase, on the other hand, is an open-source alternative to Firebase and offers comprehensive app development features along with authentication. It also supports various social login providers and has customizable components for React. Supabase's free tier also includes 50,000 MAUs, and its Pro plan offers 100,000 MAUs for $25/month. The choice depends on whether you prefer tighter integration with AWS services or an open-source platform with broader app development capabilities.
