Scales to 100s of Millions
Every aspect and component of FusionAuth was built to scale. Don't worry about things slowing down like other solutions. FusionAuth can always keep pace with even 100s of millions of users.
FusionAuth's APIs are all stateless. This means that you can easily horizontally scale nodes to handle increased volume.
FusionAuth uses Elasticsearch for our full-text search engine. Elasticsearch can be clustered and horizontally scaled to meet your needs.
FusionAuth provides Docker and Kubernetes configuration that makes auto-scaling simple.
While some components of FusionAuth use sessions and require session pinning, our sessions are lightweight. This means a single server can handle tens of thousands of sessions or more.
FusionAuth is complete auth for any app
FusionAuth is a complete solution with no sacrifices.
We got this. Go build something awesome.
