Why FusionAuth

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.

Auth You Can Own

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.

We Believe …

In Testing, Auth Should Be as Local as Your Databases

A Dedicated Architecture Is More Scalable and Performant

You Should Outsource Authentication… But Not Your Identity

Auth Pricing Should Be 100% Transparent From the Get-Go

Auth Should Be …

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 In Dedicated Infrastructure

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.

Customization Without Limits

We 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.

Transparent Pricing

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