AWS AmplifySupabase vs AWS Amplify: Complete Comparison (2026)
In-depth comparison of Supabase and AWS Amplify. Compare pricing, features, pros & cons to find the best backend-as-a-service for your team.
Introduction
When building modern web and mobile applications, developers often reach for a Backend‑as‑a‑Service (BaaS) that can handle authentication, data storage, and real‑time sync without the overhead of managing infrastructure. Supabase and AWS Amplify sit at opposite ends of the ecosystem spectrum: Supabase is an open‑source, PostgreSQL‑centric Firebase alternative, while Amplify is Amazon’s fully managed full‑stack platform that leans on the broader AWS service catalog.
This article dives deep into the technical and financial aspects of both platforms. We’ll compare company backgrounds, pricing structures, core capabilities, pros & cons, and finally recommend which tool fits specific use‑cases.
Quick Verdict
SupabaseAWS AmplifyCompany & Background
| Tool | Origin & Positioning |
|---|---|
| Supabase | Launched in 2020, Supabase is built by a small team of ex‑Postgres engineers. It markets itself as the open‑source Firebase alternative, offering a managed Postgres database, authentication, storage, and real‑time APIs. The platform is hosted by Supabase.io but can also be self‑hosted. |
| AWS Amplify | Part of Amazon Web Services, Amplify was introduced in 2017 to simplify full‑stack development on AWS. It bundles a CI/CD pipeline, static web hosting, and a suite of managed backend services (Cognito, AppSync, DynamoDB, Lambda, S3). Amplify is positioned for enterprise‑grade scalability and tight integration with the rest of the AWS ecosystem. |
Pricing Comparison
Value discussion
-
Supabase – Two fixed tiers with predictable monthly cost. The Free tier includes a modest Postgres instance and authentication; the Pro tier unlocks higher storage, additional auth users, and priority support. No per‑minute or per‑GB usage fees, making budgeting straightforward.
-
AWS Amplify – A generous always‑free tier that covers most small‑project needs. Beyond that, every resource (build compute, storage, data transfer, SSR) is metered. This pay‑as‑you‑go model can be cost‑effective for bursty workloads but requires careful monitoring to avoid surprise charges.

Analysis of key rows
| Feature | Supabase | AWS Amplify | What it means |
|---|---|---|---|
| Open‑source | ✅ | ❌ | Supabase’s core services can be self‑hosted; Amplify is proprietary. |
| PostgreSQL | ✅ | ❌ | Direct SQL access and relational modeling vs. Amplify’s NoSQL DynamoDB. |
| Auth | ✅ (Supabase Auth) | ✅ (Cognito) | Both provide email/password, OAuth, and JWT tokens. |
| Realtime | ✅ (via Postgres replication) | ❌ | Supabase pushes changes over websockets; Amplify requires custom AppSync setup. |
| Managed Backend Services | ❌ | ✅ | Amplify bundles a suite of AWS services out‑of‑the‑box. |
| Automatic Scaling | ❌ | ✅ | Amplify automatically scales hosting and compute; Supabase requires manual scaling of the hosted instance. |
| Pay‑as‑you‑go | ❌ | ✅ | Supabase charges fixed monthly tiers; Amplify meters usage. |
| SSR Support | ❌ | ✅ | Amplify can host Next.js or Nuxt SSR with built‑in pricing. |
| Pre‑built UI | ❌ | ✅ | Amplify UI components accelerate front‑end development. |
| CI/CD | ❌ | ✅ | Amplify integrates directly with Git repos for automated builds. |
Pros & Cons
Supabase — Pros & Cons✓Pros
- Open‑source stack – full control and self‑hosting possible
- SQL‑first backend (PostgreSQL) with powerful relational queries
- Predictable tiered pricing (Free & $25 /mo Pro)
- Built‑in realtime subscriptions without extra services
- Straightforward auth and storage APIs
✗Cons
- No native server‑side rendering or built‑in CI/CD pipeline
- Limited automatic scaling – you must upgrade the hosted tier manually
- Ecosystem smaller than AWS; fewer managed services (no DynamoDB, Lambda, etc.)
- Enterprise‑grade features (e.g., WAF) require external setup
AWS Amplify — Pros & Cons✓Pros
- Deep integration with the entire AWS ecosystem (Cognito, AppSync, DynamoDB, Lambda, S3)
- Always‑free tier with generous limits for small projects
- Pay‑as‑you‑go model lets you scale cost with usage
- Built‑in CI/CD, branch deployments, and pre‑built React UI components
- Automatic scaling of hosting and compute resources
✗Cons
- Pricing can become complex; requires careful monitoring of build minutes, storage, and data transfer
- Vendor lock‑in to AWS services; migration is non‑trivial
- Free tier caps (e.g., 1,000 build minutes) may be insufficient for heavy CI pipelines
- Less transparent for SQL workloads – relies on DynamoDB or Aurora rather than native Postgres
Ideal Use Cases
| Scenario | Recommended Tool |
|---|---|
| Start‑up MVP with relational data | Supabase – Quick SQL setup, predictable cost, open‑source flexibility. |
| Enterprise web app needing tight AWS integration (Cognito, Lambda, etc.) | AWS Amplify – Leverages existing AWS accounts, built‑in security (WAF), and automatic scaling. |
| Team that wants a free CI/CD pipeline and SSR out of the box | AWS Amplify – Free build minutes and SSR support. |
| Projects that must avoid vendor lock‑in or require on‑prem/self‑hosted deployment | Supabase – Open‑source code can be run in any cloud or on‑premises. |
| Heavy real‑time collaborative apps (e.g., chat, dashboards) | Supabase – Native realtime over Postgres simplifies implementation. |
| Applications with bursty traffic and uncertain load | AWS Amplify – Pay‑as‑you‑go and automatic scaling keep costs aligned with demand. |
Final Recommendation
Both Supabase and AWS Amplify are powerful BaaS options, but they solve different problems.
If your priority is an open‑source, SQL‑first backend with simple, predictable pricing, Supabase wins. It gives developers full control over data, a minimal learning curve for anyone familiar with PostgreSQL, and a clear $0 or $25 /mo cost structure.
If you already live in the AWS ecosystem, need out‑of‑the‑box server‑side rendering, and want a fully managed CI/CD pipeline that scales automatically, AWS Amplify is the logical choice. Its pay‑as‑you‑go model can be economical for variable workloads, but you must monitor usage to stay within budget.
Bottom line: choose Supabase for developer‑centric, relational‑data projects with fixed budgets; choose AWS Amplify for enterprise‑grade, AWS‑integrated applications that demand auto‑scaling and a broader set of managed services.
