What Our Customers Are Saying

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!

Nathan Carlson

Great tool! And all the right features plus awesome support.

Chris Obdam
Betty Blocks

The FusionAuth team has been extremely helpful. They really give you the attention you need to solve any identity challenge.

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 an amazing product. Tons of features and the support is the best in the industry."

Marc Pearson
IT Consultant

I achieved in a single day's work what took a week and a half with Gluu. FusionAuth is just that simple to use.

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

FusionAuth works great for small companies with small budgets. Community Edition has tons of features and Developer Edition is startup budget friendly.

Jordi Mèlich

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.
