Better Than Saas Solutions

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.

Nathan Carlson

"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."

Chris Obdam, Betty Blocks

"Great tool, just the right features."

Danny Davis, Wonder Giant

"The FusionAuth team has been so helpful. They really give you the attention you need to solve your identity challenges."

Mirza Fazlic

"I am blown away by FusionAuth. You just saved us $800-$1,500 per month from Auth0 pricing. They're gonna hate you."

Marc Pearson, IT Consultant

"FusionAuth is so good and the support is so kind."

Mike Rees, Growth Partners

"I achieved in a single day's man-hours what took a week and a half's worth of man-hours with Gluu."

Scott Plunket, WWT

"We almost purchased Auth0, but we found FusionAuth and we all thought it was too good to be true. It's not."

Jordi Mèlich, Becquel

"Also, small companies need a fine authentication."

Dan Spiteri, Hero Balancer

"It's a real huge benefit for us that [we can host Fusionauth] ourselves, so not only do we have extremely low latency for API calls, but also no rate limits which made some requests [from our previous solution] take really long to load."
