Google's app development platform
Google's app development platform with realtime database, auth, and hosting.
Google's backend-as-a-service for web and mobile apps, bundling databases, authentication, hosting, serverless functions, storage and analytics, with two plans.
Firebase is Google's app development platform. It provides a NoSQL database (Firestore or Realtime Database), authentication, file storage, hosting, serverless Cloud Functions, push messaging and analytics, so you can ship an app without running servers.
Firebase bundles the backend services most web and mobile apps need into one Google-managed platform. Firestore and the Realtime Database store and sync data in real time; Authentication handles sign-in; Hosting and App Hosting serve web content; Cloud Functions run backend logic; Cloud Storage holds files; and Analytics, Messaging and A/B Testing round it out.
Pricing has just two plans. Spark is a genuinely free tier with fixed monthly quotas and no payment method required; it enforces hard cut-offs when limits are hit. Blaze is pay-as-you-go: it includes the same free quotas, then meters each service per unit above them, Firestore reads and writes, storage, bandwidth, function invocations and messaging. New Blaze projects often get $300 in Google Cloud credit.
Small apps frequently run at $0, even on Blaze, if they stay within free quotas. There's no flat paid 'plan price', the bill is whatever the meters add up to, with bandwidth often the deciding line.
Databases, auth, hosting, functions, storage, messaging and analytics in one platform.
Firestore and Realtime Database sync data live across clients.
Spark needs no payment method and enforces hard limits.
Blaze includes free quotas, then bills per unit above them.
