OAuth vs AWS Amplify

The security dance everyone hates but can't live without meets aws's 'easy button' for full-stack apps that works great until you need to escape its walled garden. Here's our take.

OAuth

Nice Pick

The security dance everyone hates but can't live without. Delegating access without sharing passwords, because trust is a token.

Pros

• Eliminates password sharing for third-party apps
• Standardized across major platforms like Google and Facebook
• Granular scopes for fine-grained access control

Cons

• Implementation complexity leads to frequent security flaws
• Token management can be a debugging nightmare

AWS Amplify

AWS's 'easy button' for full-stack apps that works great until you need to escape its walled garden.

Pros

• Tight integration with AWS services like Cognito, AppSync, and S3 out of the box
• CLI and UI that simplify deployment, hosting, and backend setup for React, Next.js, and other frameworks
• Built-in CI/CD pipelines and environment management for rapid prototyping
• Generous free tier for small projects and startups

Cons

• Vendor lock-in: migrating away from Amplify often requires rewriting chunks of your backend
• Limited customization for complex use cases—you'll hit walls if you need fine-grained control over infrastructure

The Verdict

These tools serve different purposes. OAuth is a authentication while AWS Amplify is a hosting & deployment. We picked OAuth based on overall popularity, but your choice depends on what you're building.

The Bottom Line

OAuth wins

Based on overall popularity. OAuth is more widely used, but AWS Amplify excels in its own space.
