FusionAuth is a single-tenant CIAM solution that deploys on-premises, in your private cloud, or on their fully-managed FusionAuth Cloud. Their JSON REST API provides advanced identity management that is easy for developers to deploy and implement on any platform or framework.
"It's a huge win for us that we can self-host FusionAuth. Not only do we have extremely low latency for API calls, but also no rate limits. We were previously with Auth0 and their APIs and UIs were rate limited. This often made them horrifically slow."
