# Backend as a Service <!-- cSpell:words Supabase --> - [Firebase](https://firebase.google.com), established and widely used. More builtin features such as notifications and analytics. NoSQL, complex query can be difficult. Vendor lock-in. - [Supabase](https://supabase.com), "fake open-source", can be self-hosted but features very limited. A popular alternative to Firebase. Built on [[postgres|PostgreSQL]], which offers greater flexibility. - [PocketBase](https://pocketbase.io), extremely lightweight and easy to deploy (single binary). Designed for self-hosting. Lacks certain features but would be enought for most development.
