AWS Amplify vs Supabase
AWS Amplify and Supabase are both full-stack development platforms, but Amplify is tightly integrated with AWS services and ideal for large enterprises, while Supabase provides a more lightweight, PostgreSQL-native alternative suited for startups and cost-conscious teams.
AWS Amplify
A full-stack development platform by Amazon that provides frontend hosting, backend APIs, authentication, and database services integrated with AWS infrastructure. Built for developers wanting seamless AWS ecosystem integration.
Founded
2018 (as AWS service)
Database
RDS, DynamoDB, or custom
Pricing Model
Pay-as-you-go per AWS service
Open Source
Partially (CLI is open source)
Pros
- Deep AWS integration with Lambda, RDS, DynamoDB, Cognito, and 200+ AWS services
- Enterprise-grade scalability and security with AWS compliance certifications
- Comprehensive documentation and large community support
Cons
- Steeper learning curve and more complex setup compared to alternatives
- Can become costly at scale due to per-service AWS pricing
- Vendor lock-in to AWS ecosystem makes migration difficult
Supabase
An open-source Firebase alternative built on PostgreSQL that provides a managed backend with real-time APIs, authentication, and instant auto-generated REST/GraphQL endpoints. Designed for rapid prototyping and cost efficiency.
Founded
2020
Database
PostgreSQL (only)
Pricing Model
Free tier + fixed tiers; self-hosted option
Open Source
Yes (Apache 2.0)
Pros
- PostgreSQL foundation provides powerful, familiar relational database with advanced features
- Significantly lower costs than AWS Amplify, especially for startups and small teams
- Open-source core allows self-hosting and full transparency; minimal vendor lock-in
Cons
- Smaller ecosystem and community compared to AWS offerings
- Limited integration with non-database services (e.g., messaging, payment processing)
- Scaling beyond moderate traffic requires more manual DevOps work
Supabase wins
Supabase wins for most modern development workflows due to lower cost, simpler onboarding, open-source transparency, and PostgreSQL familiarity, though Amplify remains superior for large enterprises requiring deep AWS integration.
AWS Amplify
Best for: Enterprise applications, AWS-native ecosystems, high-compliance requirements, and teams with existing AWS expertise.
Supabase
Best for: Startups, indie hackers, cost-conscious teams, rapid prototyping, and developers favoring PostgreSQL and open-source tooling.
Feature & Architecture Comparison
| Aspect | AWS Amplify | Supabase |
|---|---|---|
| Database | RDS, DynamoDB, or bring-your-own | PostgreSQL exclusively |
| Authentication | Cognito (or third-party integrations) | Built-in Auth (JWT, OAuth, MFA) |
| Real-time APIs | GraphQL and REST (via AppSync) | Built-in real-time subscriptions (WebSocket) |
| Hosting | AWS infrastructure (CloudFront, S3, Lambda) | Managed Supabase cloud or self-hosted |
| Third-party Integrations | 200+ AWS services; extensive ecosystem | Limited; PostgreSQL extensions and webhooks |
| Learning Curve | Steep (AWS concepts, IAM, service configuration) | Gentle (familiar SQL + simple API generation) |
Cost & Scalability Profile
Cost for Small Projects
Supabase free tier suits hobby projects; Amplify requires AWS account and minimal service charges even at zero traffic.
Cost at Scale (1000+ concurrent users)
Amplify's reserved capacity and volume discounts become advantageous; Supabase pricing tiers cap benefits at high traffic.
Enterprise Scalability
Amplify auto-scales with AWS's global infrastructure; Supabase requires manual scaling or self-hosting for extreme load.
Predictability of Costs
Amplify per-service pricing can surprise; Supabase fixed tiers provide transparent, predictable monthly costs.
Operational Overhead
Amplify requires managing IAM, VPCs, and multiple services; Supabase provides managed simplicity with less configuration.
Use Case Alignment
Choose Amplify if you are building enterprise applications within AWS, require advanced integrations with analytics, ML, or payment systems, or need global scale with compliance requirements. Choose Supabase if you prioritize rapid prototyping, cost efficiency, want a PostgreSQL-first approach with transparency, or plan to self-host for maximum control.

Frequently Asked Questions
Supabase is better: its free tier and transparent pricing let you launch without AWS account overhead, and PostgreSQL is simpler to learn than AWS's service-oriented architecture. Amplify incurs costs even at low traffic.
Amplify is an AWS-integrated full-stack platform for enterprises; Supabase is a lightweight, PostgreSQL-based, open-source alternative designed for simplicity and cost. Amplify scales to any enterprise need but with vendor lock-in; Supabase offers transparency and self-hosting freedom.
Yes. Supabase is open-source and fully self-hostable on your own infrastructure. Amplify is AWS-only and managed exclusively by Amazon; self-hosting is not an option.
