- Self-hosting gives more control than hosted-only identity platforms.
- Good documentation and developer-friendly APIs.
Cons
- Interface feels less polished than larger identity platforms.
- Smaller ecosystem than major CIAM vendors.

Verdict
FusionAuth does a strong job covering authentication, single sign-on, and OAuth/OIDC workflows without heavy vendor lock-in. It is best for teams that want a practical identity platform they can run themselves or deploy quickly. The main trade-off is a less mature ecosystem compared with large hosted identity providers.
