Review Firebase?

Reviewers mostly see Firebase as a fast way to ship, especially for auth, Firestore, realtime features, and cross-platform apps, with several users praising low costs, solid APIs, and documentation that helps them get moving. Makers of Kipps AI, AskNeo, and rtrvr.ai also point to push notifications, quick iteration, built-in auth, and scaling. The main complaints are rising complexity tied to Google Cloud, billing and configuration anxiety, weak beginner friendliness, read limits, analytics friction, and Firestore’s awkward fit for relational data.

What's great

fast performance (11)easy setup (10)cloud storage (5)analytics (11)scalable backend (24)authentication (24)real-time database (19)

Firebase lets you go from idea to working backend in minutes. Auth, real-time database, cloud storage, hosting, analytics, it's all preconfigured and works together out of the box. For MVPs and prototypes, nothing else gets you to market faster. The real-time sync is genuinely magical for collaborative features, and the free tier is generous enough to validate ideas before spending a penny.

What needs improvement

price predictability (1)

Pricing predictability is the biggest issue, it's easy to get surprise bills if a real-time listener goes haywire or a function gets hammered. The documentation is sprawling and sometimes inconsistent between older and newer SDK versions. Vendor lock-in is real, migrating off Firebase is painful once you're deep in Firestore. And the emulator suite, while helpful, doesn't perfectly replicate production behaviour, which leads to "works locally, breaks in prod" moments.

vs Alternatives

Supabase

Supabase was the main alternative, open-source, Postgres-based, and more transparent on pricing. AWS Amplify for the full AWS ecosystem. For auth specifically, Auth0 and Clerk. I ended up moving to Supabase for production work because I wanted SQL, row-level security, and predictable pricing, but Firebase is still my go-to for rapid prototyping and hackathons.

used Firebase to build Retina instead of Supabase, Convex

•3 reviews

Firebase handles Retina's auth, license sync across a user's devices, and crash telemetry. Single SDK for an Electron app, generous free tier, and Google-backed reliability we don't have to babysit. Supabase was the closest second — Postgres familiarity is nice — but Firebase's real-time sync and offline-first handling for a desktop app was the bigger fit. Convex was tempting but the platform lock-in gave me pause.

used Firebase to build QuitSugar

•6 reviews

Firebase simplifies the heavy lifting of backend tasks like authentication, notifications, and real-time database management. Its ready-to-use authentication service with Google and email login saved hours of development time compared to rolling out custom solutions. Firebase's real-time database capabilities enable instant syncing of user progress and collaborative challenges, making it perfect for the social features in Quit Sugar. Its tight integration with Flutter made it a natural choice over alternatives like AWS Amplify.

While Firebase has many strengths, I find it notably challenging, if not impossible, to create diagrams for tracking KPIs directly in the platform. The need to constantly reapply filters is not the most efficient way to monitor important metrics. Furthermore, I'm somewhat skeptical about the accuracy of the tracking data, which sometimes seems less precise than expected. Despite these issues, I must commend the excellent features like Authentication and Firestore that Firebase provides. These tools are fantastic and greatly simplify many aspects of app development and data handling. They certainly add significant value to the platform and make it a powerful tool for developers. I look forward to seeing how Firebase evolves to address these feedback points in future updates.

used Firebase to build Enki

•3 reviews

We chose Firebase for our authentication solution because it’s cost-effective and offers extensive customization options. One standout feature we built is a guest mode that lets users seamlessly try the app without signing up. When they're ready to commit, all user data is effortlessly transferred. Additionally, Firebase plays a key role in our per-user encryption system. By enabling encryption keys to be embedded within user tokens, Firebase ensures we can only access those keys when provided by the user. This allowed us to implement a highly secure encryption method with relative ease.

Big thanks to Firebase! Using their Crashlytics and Notifications for Watch Planner has been a game-changer. Crashlytics gave us clear insights into app stability, and setting up push notifications was incredibly easy. Firebase makes it simple to ensure a smooth user experience while keeping users engaged. Highly recommend it to any devs out there! 🙌
