I love that it is developer-oriented and super flexible. Usually, any of the competitors are extremely expensive and difficult to use, but FusionAuth makes things super smooth and easy to implement. We have utilized the Terraform integration to deploy it, making our infrastructure easier to maintain and develop.
When it comes to users, it is a smooth integration that allows the user to authenticate from any of our platforms with ease and provides all the authentication methods that we would need. We primarily use magic links to avoid using passwords, and the integration was very straightforward forward and it works like a charm.
They also provide third-party integrations, such as Kafka, that make integration with the rest of our infrastructure extremely straightforward, allowing us to utilize what we already have.
Their customer support is great, we have only had great experiences when we need to contact them.
We have more than 20,000 users and around 4,000 monthly active users, and have used this product in production for more than 4 years. Review collected by and hosted on G2.com.
Because FusionAuth is so developer-oriented, the integration with templates and UI is very complicated. There's no easy way to implement a custom theme, so it is easier to create a custom solution that uses their internal system. UX is not the best with their default system, so it's better to steer away from that completely.
It would be awesome if they allowed some kind of infrastructure peering to make the integration with existing cloud infrastructure easier and more secure without having to deploy our self-managed instance. Review collected by and hosted on G2.com.
