We got this. Go build something awesome.
Get started
Built for <devs>
We built FusionAuth from the ground up to easily integrate with any app, language, and framework. Every feature (yes, every single one) is exposed as an API giving you complete flexibility to handle any use case.
Complete identity solution
You get every feature and acronym you need: registration & login, passwordless, SSO, MFA, SAML, OIDC, OAuth, JWT, social login and more. Comply with GDPR, HIPAA, COPPA, and PCI requirements in seconds.
Works anywhere
FusionAuth installs on any platform, any computer, anywhere. Host it yourself or use FusionAuth Cloud, our fully managed SaaS hosting service.
Upgrade Your Auth
Better Than Saas Solutions
FusionAuth gives you all the features of SaaS platforms plus true data isolation, the ability to deploy anywhere, transparent & scale-friendly pricing, and awesome-sauce support.
More Secure Than Home Grown
Secure identity is massively complex. A talented dev COULD do it all, but it takes months to build, test, and maintain. Use our one-minute install and spend your resources on something that makes you money.
Simpler Than Open-Source Identity
With FusionAuth you get every feature with one easy install–no additional modules or configuration scripts to muck with. Plus, FusionAuth is built on modern technology, simple to deploy, and scalable to hundreds of millions of users. Just download, deploy, and integrate with our RESTful APIs. Simple.
Any Platform, Any Framework
Install FusionAuth anywhere and integrate anything in minutes.

The implementation is so much more intuitive than Auth0, I can run it on my own infrastructure, and out of the box it supports more than everything I need.
Nathan Carlson
Great tool, just the right features.
Chris Obdam, Betty Blocks
The FusionAuth team has been so helpful. They really give you the attention you need to solve your identity challenges.
Danny Davis, Wonder Giant
I am blown away by FusionAuth. You just saved us $800-$1,500 per month from Auth0 pricing. They're gonna hate you.
Mirza Fazlic
FusionAuth is so good and the support is so kind.
Marc Pearson, IT Consultant
I achieved in a single day's man-hours what took a week and a half's worth of man-hours with Gluu.
Mike Rees, Growth Partners
We almost purchased Auth0, but we found FusionAuth and we all thought it was too good to be true. It's not.
Scott Plunket, WWT
Also, small companies need a fine authentication.
