For over a decade, FusionAuth has been evolving auth in parallel to application development. In today’s world, every app has its own custom pipeline, so only a hybrid deployment model gives you real freedom.
FusionAuth is the only enterprise-grade auth you can actually own. Download it, deploy it anywhere, or let us host it (on your dedicated resources). Fully API-first, built for developers.

As local as your databases—download it and integrate authentication seamlessly into your workflow, just like any other database.
Dev-friendly integration with killer SDKs and docs.
No mocks needed, can use natively in your CI/CD process
Single-tenant architecture without the risk of noisy, nosy neighbors
No hidden costs - refresh tokens, extra IdPs? All included


We believe the most secure, performant auth has a dedicated, single-tenant backend. Whether you deploy in the cloud or not, you can completely avoid the risks of multi-tenant SaaS.
Learn moreWe believe you should outsource authentication, not your identity
The login screen should not have limits on customization.
Native integrations are just better.
Auth should be a native part of quick feature pushes via integrations with CI/CD, Terraform, etc.
Metadata shouldn’t be limited to 250 chars for login in-app behavior.

We believe... pricing should be 100% transparent from the get-go
