  • • $0.12/GB bandwidth
  • • $0.06 per 100K reads (Firestore)
  • • $0.18 per 100K writes (Firestore)

Best for: Predictable small to medium apps, rapid prototyping

AWS Amplify Pricing

Free Tier (12 months)

  • • 5GB storage (S3)
  • • 15GB/month bandwidth
  • • 25GB DynamoDB storage
  • • 1M Lambda requests/month

Pay as you go

  • • $0.023/GB storage (S3)
  • • $0.09/GB bandwidth

💡 Pricing Verdict

Firebase typically costs more at high scale but offers simpler, more predictable pricing. AWS Amplify can be significantly cheaper for large applications but requires AWS optimization knowledge. For apps with 100K+ monthly active users, AWS often becomes 30-50% cheaper.

When to Choose Each Platform

Choose Firebase if:

  • You're building a mobile app (iOS/Android/Flutter) and need rapid development
  • You need excellent offline support with automatic data synchronization
  • You want simpler setup and shorter learning curve for your team
  • You need real-time data synchronization as a core feature
  • You're already using Google Cloud Platform or Google services
  • You prefer NoSQL document databases over relational databases
  • You want Firebase Cloud Messaging (FCM) for push notifications

Choose AWS Amplify if:

  • You need enterprise-grade infrastructure with AWS compliance (HIPAA, SOC 2)
  • You're already using AWS services and want seamless integration
  • You need advanced customization and access to 200+ AWS services
  • You prefer GraphQL APIs and want AppSync's powerful querying capabilities
  • You have DevOps expertise and want granular infrastructure control
  • You're building at scale (millions of users) and need cost optimization
  • You need multi-region deployment and advanced disaster recovery

Migrating Between Firebase and AWS Amplify

⚠️ Migration Complexity: High

Migrating between Firebase and AWS Amplify is a significant undertaking due to architectural differences. Expect 4-8 weeks for a medium-sized application.

Firebase → AWS Amplify

Database Migration

Export Firestore documents, transform to DynamoDB schema. Consider data modeling differences between NoSQL databases.

Authentication

Migrate Firebase Auth users to Cognito. Update all client SDKs and auth flows.

Functions

Rewrite Cloud Functions as Lambda functions. Update triggers and integrations.

AWS Amplify → Firebase

Database Migration

Export DynamoDB data, transform to Firestore collections. Simplify data model for Firestore's document structure.

Authentication

Migrate Cognito users to Firebase Auth. Simpler SDK migration but requires client updates.

Functions

Convert Lambda functions to Cloud Functions. Firebase's simpler event triggers may require architecture changes.

Frequently Asked Questions

Which is better: AWS Amplify or Firebase?

Firebase is better for rapid development, mobile apps, and simpler projects with its easier learning curve. AWS Amplify is better for enterprise applications needing AWS integration, complex infrastructure, and advanced customization. Choose Firebase for speed and simplicity, Amplify for flexibility and AWS ecosystem.

Is AWS Amplify cheaper than Firebase?

AWS Amplify can be cheaper at scale due to pay-as-you-go AWS pricing, but requires more optimization knowledge. Firebase has simpler, more predictable pricing for small to medium apps. Both offer generous free tiers. Amplify becomes more cost-effective for large applications with proper AWS optimization.

Can I migrate from Firebase to AWS Amplify?

Yes, but migration requires significant effort due to different architectures. You'll need to migrate Firestore data to DynamoDB, rewrite authentication logic, update cloud functions to Lambda, and modify client SDKs. Plan 4-8 weeks for a complete migration of a medium-sized application.

Does AWS Amplify have real-time database like Firebase?

Yes, AWS Amplify supports real-time data through AppSync with GraphQL subscriptions. However, Firebase's real-time database has simpler setup and better offline support. Amplify's real-time requires GraphQL knowledge but offers more flexibility and query capabilities.
