AWS Amplify is Amazon's platform for building full-stack web and mobile apps, bundling hosting, authentication, and a data layer backed by AWS services like AppSync and DynamoDB. It's convenient if you're already on AWS, but your backend is tightly coupled to AWS's managed services and pricing.
Supabase is the open-source alternative to consider if you want a similar bundle — auth, storage, and a real-time data API — built on Postgres and deployable on your own infrastructure instead of being locked into AWS's services.
