Supabase and Auth0 by Okta are both powerful authentication solutions, but they cater to different needs and budgets. Supabase is an open-source alternative that offers a wide range of app development features including user authentication, cloud functions, and a PostgreSQL database. It offers a generous free tier with 50,000 monthly active users and a Pro plan at $25/month for 100,000 MAUs. Auth0 by Okta, on the other hand, is a comprehensive B2C identity management solution with features like social login, bot detection, and multi-factor authentication. However, its free tier is limited to 7,500 MAUs and costs $1,400/month for 20,000 MAUs, making it relatively expensive. If budget and open-source flexibility are important, Supabase might be the better choice. If you need an all-in-one package with robust security features and don’t mind the higher cost, Auth0 by Okta could be more suitable.

Both Supabase and Auth0 by Okta offer scalable authentication solutions, but they differ in their pricing models and scalability features. Supabase offers a free tier with 50,000 monthly active users and a Pro plan that supports 100,000 MAUs at $25/month, with additional costs of $0.00325 per MAU beyond that, making it cost-effective for scaling up. Auth0 by Okta’s free tier supports 7,500 MAUs, but its pricing becomes significantly higher at $1,400/month for 20,000 MAUs. While both platforms can scale well, Supabase provides a more budget-friendly option for large-scale applications, whereas Auth0 by Okta offers a more feature-rich environment at a higher cost.
