Great tool, just the right features.
The FusionAuth team has been so helpful. They really give you the attention you need to solve your identity challenges.
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 so good and the support is so kind.
I achieved in a single day's man-hours what took a week and a half's worth of man-hours with Gluu.
We almost purchased Auth0, but we found FusionAuth and we all thought it was too good to be true. It's not.
Also, small companies need a fine authentication.
