Every app requires secure, user-friendly login and authentication. It’s not only a requirement from your PM and CISO, but your customers as well.
But what about you? FusionAuth gives you, the developer, everything you need to implement auth so you don't have to build it yourself.
Only FusionAuth has Community Edition, free software with no limits on number of users. Download and run it yourself, kick the tires, no strings attached. Free Edition Download
When your project requires MFA, SSO, Passwordless, biometric ID, or social media login, we got it. We do all the standards - like Oauth, SAML, OIDC, SCIM and JWTs. Don't reinvent this stuff.
FusionAuth lets you download and run anywhere you want. On-premise or in your cloud, with Docker and K8s if you like. Or we can host it for you in AWS, with a dedicated managed service, no shared SaaS.
The implementation is so much more intuitive than Auth0. I can run it on my own infrastructure and out of the box it supports everything I need. And more!
Great tool! And all the right features plus awesome support.
The FusionAuth team has been extremely helpful. They really give you the attention you need to solve any identity challenge.
I am blown away by FusionAuth. You just saved us $800-$1,500 per month from Auth0 pricing. They're gonna hate you.
"FusionAuth is an amazing product. Tons of features and the support is the best in the industry."
I achieved in a single day's work what took a week and a half with Gluu. FusionAuth is just that simple to use.
We almost purchased Auth0, but we found FusionAuth and we all thought it was too good to be true. It's not!
FusionAuth works great for small companies with small budgets. Community Edition has tons of features and Developer Edition is startup budget friendly.
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.
This guide covers OAuth 2.0 from a real-world perspective and covers modern use cases of the specifications. It's based on hundreds client implementations and our experience building FusionAuth, an OAuth server which has been downloaded over a million times.
