Choosing the right backend for your app is a critical decision that impacts your speed, budget, and long term flexibility. When it comes to the AWS Amplify vs Supabase debate, the choice boils down to a core philosophy: do you need the unparalleled scalability and deep ecosystem of a cloud giant, or the rapid development and open source freedom of a modern, focused platform? For most startups and teams prioritizing developer experience, Supabase is the faster, more flexible choice. For enterprises needing massive scale and deep integration with other AWS services, Amplify is the more powerful option.

As a product development studio, we at Bricks Tech regularly help startup founders navigate these choices. This guide breaks down everything you need to know about AWS Amplify vs Supabase, giving you the clarity to pick the right tool for your next big idea.

What is AWS Amplify?

AWS Amplify is a development platform from Amazon Web Services that helps you build full stack web and mobile applications. Think of it as a friendly toolkit that simplifies connecting your front end app to the immense power of the AWS cloud. It bundles and infigures various AWS services like Cognito for user authentication, S3 for storage, and AppSync for APIs, hiding much of the underlying complexity.

With Amplify, you can set up a backend using a command line interface or a visual admin UI, add features with a few commands, and deploy your application quickly. It’s designed to let you focus on your app’s user experience while leveraging the battle tested, scalable infrastructure of AWS.

What is Supabase?

Supabase is an open source platform often described as an alternative to Firebase. Its core is a dedicated PostgreSQL database for every project, which comes with a suite of integrated tools right out of the box. This includes built in authentication, file storage, real time updates, and serverless functions.

The big draw for Supabase is that it gives you the full power of a relational SQL database without you having to manage the server yourself. Because it’s completely open source, you get transparency and the ability to self host the entire stack if you ever need to, avoiding vendor lock in. Its simplicity and developer friendly experience have made it incredibly popular, with its main GitHub repository amassing over 95,000 stars.

AWS Amplify vs Supabase: A Head to Head Feature Comparison

At a high level, both platforms offer similar capabilities, but their architecture is fundamentally different. AWS Amplify assembles a backend for you using multiple specialized AWS services. Supabase provides a more cohesive, all in one stack built around its Postgres database.

Here’s a quick breakdown:

• Database: Amplify typically defaults to Amazon DynamoDB (a NoSQL database) but can be configured with SQL databases like RDS. Supabase is all in on PostgreSQL (a SQL database).

• Authentication: Amplify uses AWS Cognito. Supabase has its own built in Supabase Auth.

• APIs: Amplify has a GraphQL first approach using AWS AppSync, with REST as an option. Supabase is REST first with auto generated APIs, and offers GraphQL as an extension.

• Real time: Amplify uses GraphQL subscriptions via AppSync. Supabase listens directly to database changes.

• Storage: Amplify uses Amazon S3. Supabase provides its own S3 compatible object storage.

• Serverless Functions: Amplify uses AWS Lambda. Supabase uses Edge Functions, which are powered by Deno.

The Core Difference: Database Philosophy

The database model is central to the AWS Amplify vs Supabase comparison.

SQL vs NoSQL Data Model

Supabase is built entirely on PostgreSQL, a powerful relational (SQL) database. SQL databases use structured tables with predefined columns and data types, enforcing relationships between data. This is great for applications that need strong data consistency and complex queries, like an ecommerce store where orders must be linked to customers and products.

AWS Amplify, on the other hand, often defaults to Amazon DynamoDB, a NoSQL database, especially when you use its GraphQL API tooling. NoSQL databases are more flexible, storing data in formats like documents or key value pairs. They excel at horizontal scaling and handling massive volumes of simple lookups, but they make complex relational queries (like joining data across multiple tables) more difficult.

While you can configure Amplify to use a relational database like Amazon RDS, it requires more setup. The choice here is significant: Supabase gives you SQL power and structure by default, while Amplify’s default path prioritizes the massive scalability and flexibility of NoSQL.

User Management: Authentication & Authorization

Both platforms provide robust solutions for managing user sign ups and logins.

Amplify uses Amazon Cognito under the hood. Cognito is an enterprise grade service that handles user pools, social logins (like Google or Facebook), and multi factor authentication. It’s incredibly powerful but can feel complex to configure for custom scenarios.

Supabase Auth offers a simpler, more integrated experience. It supports email and password logins, social providers, and passwordless magic links right out of the box. Its killer feature is the deep integration with the database through Row Level Security (RLS). RLS lets you write simple SQL rules that define which users can read or write specific rows of data, enforcing security directly at the database level.

Both platforms offer generous free tiers for authentication, often covering your first 50,000 monthly active users.

Building Live Experiences: Real Time Subscriptions

For features like chat apps, live notifications, or collaborative dashboards, you need real time capabilities.

Supabase makes this incredibly easy with Supabase Realtime. You can “flip a switch” on any database table, and Supabase will broadcast any changes (inserts, updates, deletes) to subscribed clients over WebSockets. It’s a simple and effective way to make your app feel alive.

Amplify enables real time functionality through AWS AppSync’s GraphQL subscriptions. You define specific events in your GraphQL schema that clients can subscribe to. This approach is powerful and granular, giving you precise control over what data is sent, but it requires more upfront schema design and configuration compared to Supabase’s direct database listening model.

Communicating with the Backend: API Support

How your front end talks to your back end is another key point in the AWS Amplify vs Supabase decision.

Amplify is heavily geared towards a GraphQL first approach with AWS AppSync. You define a data schema, and Amplify generates the API endpoints and connects them to your database. This is great for fetching complex, nested data in a single request. REST APIs are also possible using AWS API Gateway and Lambda, but it’s a more manual setup.

Supabase takes a REST first approach. As soon as you create a database table, Supabase automatically generates a full set of RESTful API endpoints for it. This is incredibly fast for getting a CRUD (Create, Read, Update, Delete) API up and running. For those who prefer it, Supabase also offers a GraphQL extension you can enable on your database. For a deeper dive into planning integrations, see our comprehensive guide to API integration.

Handling Files: Storage Solutions

Most apps need to handle file uploads like profile pictures or documents.

Amplify leverages Amazon S3, the gold standard for object storage. S3 is known for its extreme durability (99.999999999% to be exact) and massive scalability. Amplify helps you secure file access by integrating with Cognito, allowing you to set permissions for who can upload or view files.

Supabase provides its own Supabase Storage, which is an S3 compatible service. It lets you create buckets for your files and manage permissions that are tightly integrated with Supabase Auth and your database’s Row Level Security policies. While it offers more than enough power for most applications, Amplify’s direct S3 integration gives you access to the broader ecosystem of advanced AWS storage features if you ever need them.

From Code to Live: Hosting & CI/CD

When it comes to deploying your front end, the platforms have different scopes.

AWS Amplify Hosting is a complete solution for deploying and hosting modern web apps. It connects directly to your Git repository (like GitHub or GitLab) and provides a full CI/CD pipeline out of the box. When you push code, Amplify automatically builds, tests, and deploys your site to a global content delivery network (CDN), ensuring fast load times for your users worldwide.

Supabase, on the other hand, focuses purely on the backend. It does not offer front end hosting. You’ll need to use a separate service like Vercel, Netlify, or even AWS Amplify Hosting to deploy your user interface. This isn’t a downside, just a difference in focus. Supabase is designed to be your backend, no matter where your front end lives.

The Day to Day: Developer Experience & Setup

Developer experience is where you’ll feel the biggest difference between AWS Amplify vs Supabase.

Supabase is widely praised for its simplicity and speed. You can get a complete backend with a database, auth, and storage running in just a few minutes from their web dashboard. The direct access to the Postgres database makes debugging and data management very straightforward.

Amplify provides a more extensive set of tools, which can come with a steeper learning curve. The setup process is typically driven by the Amplify CLI, which automates the creation of numerous AWS resources behind the scenes. This automation is powerful, but when things go wrong, you might need to dive into the AWS console to understand the underlying services like Cognito or AppSync. To see how we de-risk setup and keep teams aligned, explore our product development process.

Planning for Growth: Scalability & Flexibility

Both platforms are built to scale, but they do so differently.

Being built on AWS, Amplify inherits its virtually limitless scalability. Services like DynamoDB and Lambda are designed to handle millions of requests per second and scale automatically with demand. This makes Amplify a safe bet if you anticipate explosive, unpredictable growth.

Supabase scales primarily by upgrading your Postgres database to a more powerful instance (vertical scaling). A single Postgres database can handle a very heavy load, and for most startups, this is more than enough to reach millions of users. The ultimate flexibility of Supabase is its open source nature; if you outgrow the managed platform, you can always migrate to a self hosted, custom Postgres cluster.

Making the right architectural choice for scale can be tricky. If you need help roadmapping your growth, discuss your project with Bricks Tech and we’ll design a solution that won’t hold you back.

Real World Impact: Performance & Latency

Performance is often tied to your architecture and where your users are.

Amplify apps can achieve very low latency. Using DynamoDB for key value lookups can return results in single digit milliseconds. Plus, Amplify Hosting uses a global CDN to serve your front end assets from locations close to your users, making your site feel snappy everywhere.

Supabase performance is tied to its powerful Postgres database, which is extremely fast for well indexed queries. However, a standard Supabase project is hosted in a single geographic region. This means users far away from that region might experience slightly higher network latency. Supabase’s Edge Functions can help run logic closer to your users, but data still ultimately resides in your primary database region.

Protecting Your App: Security & Compliance

Security is non negotiable, and both platforms offer strong protections.

Amplify benefits from the deep security and compliance framework of AWS. AWS holds numerous certifications (like SOC 2, HIPAA, and PCI DSS), which can be crucial for apps in regulated industries. Access control is managed through AWS IAM, a powerful but complex system for defining permissions. If you’re building in regulated spaces like finance, explore our fintech app development services guide.

Supabase’s security model is centered on its database. By enforcing Row Level Security, it ensures that your data access policies are applied directly to the data itself, which is a very secure and robust approach. Because it’s a newer company, its cloud offering may not have the same extensive list of compliance certifications as AWS, but its open source nature allows you to self host in a compliant environment if needed.

The Bottom Line: Pricing & Cost Models

The financial aspect is a key part of the AWS Amplify vs Supabase decision.

Supabase offers predictable, tiered pricing. It has a generous free tier that is not time limited, which is perfect for hobby projects and MVPs. Paid plans start at a flat monthly fee (around $25) and scale up from there, with the option to set spending caps to avoid surprise bills.

Amplify uses AWS’s pay as you go model. There’s no cost for the Amplify framework itself, but you pay for the usage of the underlying AWS services it provisions. AWS offers a free tier, but it’s often limited to the first 12 months for new accounts. This model can be very cost effective at low usage, but it can also be less predictable, as your bill is the sum of many different services.

Future Proofing Your Stack

Thinking about the long term involves vendor lock in, customization, and the core technology philosophy.

Vendor Lock In Risk

Supabase is designed to minimize lock in. Since it’s just Postgres and open source tools, you can easily export your data and self host the entire stack anytime, giving you complete control.

Amplify, by contrast, ties you more deeply into the AWS ecosystem. Migrating away from services like Cognito and DynamoDB to a different cloud provider would require a significant re-engineering effort.

Customization and Control

Supabase gives you incredible control because you have direct access to the database. You can write custom SQL functions, add Postgres extensions, and fine tune performance in ways that are simply not possible with a more abstracted service.

Amplify abstracts away the low level details. This convenience means you have less direct control. Customization is done through configuration and by extending your backend with other AWS services, rather than modifying the core components themselves.

Open Source vs Proprietary

This is a fundamental divide. Supabase is proudly open source. You can see the code, contribute to it, and trust in a community driven platform. AWS Amplify’s client libraries are open source, but the backend services like Cognito and AppSync are proprietary, closed source technologies.

The Power of Community: Ecosystem & Integrations

No tool exists in a vacuum. The surrounding ecosystem is vital.

Amplify taps into the massive AWS ecosystem. You can seamlessly integrate your app with over 200 AWS services, from machine learning (SageMaker) to data analytics (Kinesis). If there’s a cloud capability you need, AWS almost certainly has a service for it.

Supabase connects you to the rich open source and Postgres ecosystems. Any tool or library that can talk to Postgres can work with Supabase. Its community is vibrant and growing rapidly, with active support on platforms like Discord and GitHub.
