Best Backend Platforms for Your Next App in 2026

Backend-as-a-service platforms handle auth, database, and storage so you don't build them from scratch. Supabase (Postgres, open-source) and Firebase (Google, NoSQL) are the two leading all-in-one options. Railway and Retool round out the category for general app hosting and internal tools respectively, while Clerk specializes specifically in authentication if you want to mix and match rather than use an all-in-one platform.

FAQ

Should I use Supabase or Firebase?
Supabase gives you a relational Postgres database and open-source flexibility; Firebase offers Google's mature, battle-tested mobile SDKs and NoSQL data model.
Do I need a separate auth provider if I use Supabase or Firebase?
No, both include built-in authentication, though some teams use a dedicated provider like Clerk for a more customizable auth UI.
What's the difference between Railway and a backend-as-a-service platform?
Railway is general-purpose app/database hosting; Supabase and Firebase are more opinionated platforms that bundle auth, database, and storage together.
