We rate Firebase 4.2/5. Extremely fast to prototype with, making it especially useful for solopreneurs and startups. The main tradeoff: vendor lock-in to google ecosystem. The free tier softens this considerably.
About Firebase
Firebase is Google's app development platform, providing backend services that let developers focus on building user-facing features. It includes authentication, databases, hosting, storage, cloud functions, and analytics.
The free Spark plan is generous: 50K auth users, 1GB Firestore storage, 5GB Cloud Storage, 125K Cloud Function invocations, and 10GB hosting bandwidth. The Blaze pay-as-you-go plan charges for usage above free tier limits.
Firebase's strength is speed of development. Authentication supports email, Google, Apple, Facebook, and phone sign-in with minimal code. Firestore (NoSQL database) syncs data in real-time across web and mobile clients. Cloud Functions run server-side logic without managing servers.
For solo founders, Firebase's free tier can serve thousands of daily active users at $0. The combination of auth + database + hosting covers most app needs. Firebase Hosting with CDN serves static sites globally.
Limitations: Firestore is NoSQL only (no relational queries, no joins), vendor lock-in to Google Cloud, costs can spike unexpectedly with usage, and the pricing model is complex. Supabase offers a Postgres-based alternative with similar features and better pricing predictability.
