Backend-as-a-Service
Platforms that hand an application its entire backend as a managed service: a database, authentication, file storage, realtime subscriptions and serverless functions behind one SDK. The category exists as an answer to Firebase, and unlike Firebase every entrant ranked here publishes the server you would run, so each can be judged on evidence anyone can re-check.
