Where can I find a platform that combines database, auth, and storage for my app?

Yes — what you’re looking for is generally called a Backend-as-a-Service (BaaS): one platform that gives you a database, authentication, file storage, APIs, and often additional backend features.

Best options

1. Supabase — my top recommendation

   • Full PostgreSQL database
   • Built-in authentication (email/password, magic links, OAuth, SSO, etc.)
   • File storage with access controls
   • Row Level Security (RLS) ties authentication directly to database permissions
   • Open-source components and a relatively standard Postgres foundation

   Great for: SaaS apps, dashboards, marketplaces, web apps, and developers who want SQL/Postgres.

2. • Authentication
   • Databases
   • File storage
   • Serverless Functions
   • Realtime and messaging
   • Can be used as a managed cloud service or self-hosted.

   Great for: developers who want an all-in-one, open-source backend and especially those interested in self-hosting.

3. • Authentication
   • Firestore / Realtime Database
   • Cloud Storage
   • Lots of additional Google Cloud integrations
   • Particularly strong for mobile applications.

   Great for: mobile apps, rapid prototypes, and apps already invested in the Google ecosystem.

Quick recommendation

If you're starting a new web app, I'd look at Supabase first. Its Postgres database is a real PostgreSQL database rather than a proprietary abstraction, while Auth and Storage integrate directly with it.

If you tell me what you're building (e.g. Next.js SaaS, mobile app, AI app, marketplace), I can recommend the best platform and stack for it.

You can find platforms that combine database, authentication, and file storage—known as Backend-as-a-Service (BaaS) providers—on major developer tools platforms like Supabase or Firebase.
