Firebase vs AWS Amplify: Google vs Amazon for App Backends
Rapid prototyping with Firebase's ecosystem or enterprise scalability on AWS infrastructure with Amplify? Your growth ambitions determine the winner.
Firebase and AWS Amplify serve the same Backend-as-a-Service market but with fundamentally different philosophies. Firebase prioritizes simplicity and speed above all else. You can have a fully working backend within minutes with authentication, database, hosting, and analytics without writing a single line of infrastructure code. Amplify offers more power, flexibility, and scalability but requires significantly more knowledge of the AWS ecosystem and a steeper learning curve. Firebase is the better choice for rapid prototypes, mobile apps, and teams without DevOps capacity. Amplify is better suited for enterprise projects requiring maximum scalability, GraphQL support, and deep AWS integration. Both platforms carry vendor lock-in that you should carefully consider before making a long-term commitment.
Background
Backend-as-a-Service platforms like Firebase and Amplify significantly lower the barrier to app development by abstracting away infrastructure complexity. However, the choice between these platforms has long-term consequences for vendor lock-in, scalability, and the flexibility of your architecture. Firebase dominates the BaaS market for mobile and web apps thanks to its simplicity, while Amplify bridges the gap to the enterprise segment via the underlying AWS infrastructure. This comparison is especially relevant for teams that want to start quickly without a full backend team but also think ahead about how their choice scales as the product grows.
Firebase
Firebase is Google's Backend-as-a-Service platform offering a complete suite for rapid app development. With Firestore as a NoSQL document database with real-time synchronization, Firebase Authentication supporting 20+ identity providers, Cloud Functions for serverless backend logic, Firebase Hosting for CDN distribution, and Analytics for usage insights, Firebase provides an exceptionally accessible way to quickly build working applications. The platform is known for its simple setup that becomes operational within minutes, robust offline sync for mobile apps, and excellent SDKs for iOS, Android, and web.
AWS Amplify
AWS Amplify is Amazon's answer to Firebase, offering a comprehensive set of tools and services to build full-stack applications on scalable AWS infrastructure. Amplify delivers a native GraphQL API via AppSync with real-time subscriptions, authentication via Cognito with enterprise SSO support, storage via S3, and hosting for both web and mobile apps. The platform is more powerful and scalable than Firebase thanks to the underlying AWS services but brings substantially more complexity in both initial setup and day-to-day management.
What are the key differences between Firebase and AWS Amplify?
| Feature | Firebase | AWS Amplify |
|---|---|---|
| Ease of setup | Very simple: Firebase console and SDK operational within minutes with minimal configuration needed | More complex with CLI-driven setup, YAML configuration, and multiple AWS services provisioned under the hood |
| Database | Firestore (NoSQL document database) with real-time sync and offline support for mobile applications | DynamoDB (NoSQL) or Aurora Serverless (SQL) via the AppSync GraphQL layer with flexible data modeling |
| API type | REST via Cloud Functions with HTTP triggers, no native built-in GraphQL support | Native GraphQL via AWS AppSync with real-time subscriptions, offline sync, and automatic code generation |
| Authentication | Firebase Auth: simple with 20+ social and enterprise providers, free up to 50K MAU at no extra cost | AWS Cognito: powerful with enterprise SSO (SAML, OIDC), MFA, and user pools, but more complex initial setup |
| Scalability | Automatic but with Firestore limits at 10K writes/second per database and 1 MB document size cap | Virtually unlimited scalability thanks to DynamoDB, Lambda, and other underlying AWS services that auto-scale |
| Vendor lock-in | High: no self-hosting possible, fully Google Cloud dependent with proprietary data formats | Medium: AWS-bound but more migration paths via open standards like GraphQL and SQL via Aurora |
| Mobile SDKs | Excellent native SDKs for iOS, Android, Flutter, and React Native with deeply integrated features | SDKs for iOS, Android, and React Native, less refined than Firebase but with broader AWS integration |
| Cost at scale | Blaze pay-as-you-go can escalate quickly at high read/write volumes due to per-operation pricing model | AWS pricing is more complex but often more cost-effective at high volumes thanks to Reserved Capacity |
When to choose which?
Choose Firebase when...
Choose Firebase when speed-to-market is your top priority and you want a working backend within hours rather than days. Firebase is ideal for mobile-first applications that benefit from offline sync, push notifications, and real-time database updates. Also choose Firebase when your team has limited backend experience and needs a platform with minimal configuration. Firebase excels for MVPs, hackathon projects, and applications with under 50,000 monthly active users that fit within the generous free Spark plan.
Choose AWS Amplify when...
Choose AWS Amplify when your organization is already invested in the AWS ecosystem and needs seamless integration with services like Cognito, AppSync, S3, and Lambda. Amplify is better suited for enterprise projects requiring unlimited scalability, complex authorization rules via GraphQL resolvers, and enterprise-grade SSO configuration with SAML or OIDC. Choose Amplify when you prefer a SQL database (Aurora) over Firestore NoSQL.
What is the verdict on Firebase vs AWS Amplify?

You can have a fully working backend within minutes with authentication, database, hosting, and analytics without writing a single line of infrastructure code.

Which option does MG Software recommend?
At MG Software, we recommend neither Firebase nor Amplify as the primary backend for new projects; we choose Supabase for its combination of an open-source PostgreSQL database, Row Level Security, real-time subscriptions, and full control over your data without vendor lock-in. When clients are considering one of these two, we recommend Firebase for quick MVPs, mobile apps, and teams without backend experience. Amplify we recommend for organizations already deeply invested in the AWS ecosystem that need enterprise scale. Our core advice is always to minimize vendor lock-in and maintain ownership of your data.
Migrating: what to consider?
Migrating from Firebase to Amplify requires substantial adjustments to your entire backend architecture. Firestore documents must be migrated to DynamoDB or Aurora, which involves a schema redesign. Firebase Auth users must be transferred to Cognito, where password hashes are not always directly transferable. Cloud Functions must be rewritten as Lambda functions. AppSync's GraphQL layer differs fundamentally from Firebase's REST approach and requires new client code. Plan at least 4-8 weeks for a complete migration and consider a phased approach per service to limit risks.
