Firebase
firebase.google.comBackend
Google's original BaaS — realtime NoSQL, auth, and hosting in one console; still the fastest path from zero to a working app.
Other products from Backend
An open-source, self-hostable Firebase alternative — the same auth, database, and storage bundle, minus getting locked into Google's cloud.
A single Go binary that ships a full backend — SQLite, auth, file storage, and realtime subscriptions — deployable anywhere in minutes.
Your database and server functions live in one reactive TypeScript codebase, so every client just stays in sync without you writing the plumbing.
