AWS Amplify vs Supabase
AWS Amplify and Supabase are both backend-as-a-service platforms, but they differ fundamentally in architecture and ecosystem. Amplify is deeply integrated with AWS services and targets enterprise teams, while Supabase emphasizes PostgreSQL and real-time features for rapid development.

Feature & Capability Comparison
| Aspect | AWS Amplify | Supabase |
|---|---|---|
| Database Engine | DynamoDB, RDS, Aurora, or multi-DB choice | PostgreSQL only |
| Real-time Features | GraphQL subscriptions (via AppSync); polling-based | Native real-time subscriptions built-in |
| Authentication | Amazon Cognito with enterprise SSO | Auth via Supabase Auth (JWT-based) |
| Hosting & Deployment | Amplify Hosting + CloudFront CDN | Managed cloud or self-hosted |
| API Generation | GraphQL API, REST via API Gateway | Auto-generated REST & GraphQL APIs |
| Open Source | Proprietary (AWS-managed) | Fully open-source on GitHub |
Developer Experience & Learning Curve
Ease of Setup
Supabase has a faster initial setup with one-click database provisioning; Amplify requires AWS account familiarity and CLI configuration.
Documentation Quality
Both have comprehensive guides; AWS docs are deeper but denser, while Supabase docs are more concise and beginner-friendly.
Real-time Development
Supabase makes real-time subscriptions effortless; Amplify requires AppSync configuration or polling workarounds.
Ecosystem & Extensions
Amplify integrates with entire AWS ecosystem; Supabase has growing integrations but fewer third-party connectors.
Cost Transparency
Supabase uses clear per-project pricing; Amplify costs accumulate across multiple AWS services, harder to predict upfront.
Pricing & Cost Model
Supabase offers a free tier plus straightforward per-project pricing ($25–$100+/month depending on usage), making it predictable for startups. Amplify charges per consumed service (compute, storage, database, bandwidth), which scales well but requires detailed cost monitoring; enterprise contracts are available. For simple prototypes, Supabase is cheaper; for complex, multi-service architectures, Amplify's per-component pricing can become more expensive without careful management.
When to Choose Each Platform
Choose Amplify if you need enterprise-scale infrastructure, are already invested in AWS, need complex workflows across multiple services, or require compliance certifications like SOC 2 Type II. Choose Supabase if you want rapid development, prefer PostgreSQL, value open-source flexibility, need real-time features without complexity, or are building a prototype or MVPs with limited DevOps resources.
Who should choose which
Frequently Asked Questions
Supabase is better because its native real-time subscriptions are designed for this use case with minimal configuration, whereas Amplify requires AppSync setup or polling workarounds. Supabase also costs less for early-stage projects.
Amplify is a comprehensive AWS-integrated platform for enterprise apps; Supabase is a lightweight, PostgreSQL-first backend focused on speed and simplicity. Amplify locks you into AWS but offers more services; Supabase is open-source and can be self-hosted for independence.
Yes, Supabase is fully open-source on GitHub and can be self-hosted, giving you complete control. Amplify is proprietary to AWS, though individual components (like Amplify CLI) are open-source; you cannot self-host the full platform.
