Why consider switching
- Developer experience + documentation gaps relative to modern CIAM
- Limited customization of hosted UI + flows
- User-pool migration + export friction (lock-in concerns)
- Advanced features (passkeys, B2B org management) lag competitors
Why staying may be right
- Deeply integrated with AWS IAM + API Gateway + AppSync authorizers
- No separate vendor — billing + support stay within AWS
- Generous free tier; low cost at modest scale
- Adequate for straightforward B2C auth inside an AWS stack

How to pick the right alternative for your environment.
1. How locked into AWS are you?
If deeply AWS-native (API Gateway authorizers, AppSync), the integration cost of leaving Cognito is real — weigh it against the DX gain.
2. Is per-MAU cost a concern at scale?
Keycloak/SuperTokens (self-host) keep economics flat; managed options reintroduce per-MAU pricing.
3. Microsoft or AWS estate?
Microsoft External ID is the natural pick for Azure-aligned orgs.
