Backend-as-a-Service (BaaS)
A backend-as-a-service (BaaS) is a platform that provides ready-made backend building blocks — database, authentication, storage, and an API — so developers don't have to build and operate them from scratch.
A backend-as-a-service removes the undifferentiated work of standing up a backend. Instead of wiring a database, an auth system, file storage, and an API layer yourself, a BaaS exposes them as managed services you configure and call.
Typical BaaS features include a hosted database, user authentication (email and OAuth), object storage for files, and an automatically generated API. Many also offer serverless functions, realtime updates, and an admin dashboard.
BaaS is most valuable when the backend is undifferentiated work — most apps need the same accounts, data, and storage plumbing. Teams building on standard technologies like PostgreSQL also keep portability, avoiding lock-in.
