FusionAuth Reviews

Summary: It's been a pleasure to use FusionAuth and a great step up from a home-grown solution. The free tier makes this an easy sell to management, with paid options for more advanced features. New features are being added all the time to make it even better.

Positive: - Highly customisable
- Support for many standards
- Free tier and reasonable pricing with various tiers for paid options
- Various guides on migrating from home-grown solutions provided
- Scalable with "just works" multi-node support out of the box
- Very active in supporting issues/feature requests
- Self-hosted options

Negative: - Currently with a multi-node system, downtime is required to upgrade when DB migrations are necessary
- Currently no support for API-initiated SSO
- Some advanced functionality locked behind the higher paid tiers

Summary: I've found it much easier to work with than Keycloak and Azure B2C while providing the features I need.

Positive: Easy to set up and use.
Solid community.
Decent documentation.
Good customization options.
Comprehensive password policy settings.

Negative: Global CORS configuration instead of per application.

Summary: Still not at all fully acquainted with all of the features which FusionAuth provides, so we still have much to discover.

Positive: - Configurable with templates to the house style
- Gives a real sense of security
- Many different ways of logging in

Negative: - Version numbering: 2FA functionality broke between 1.28 and 1.30; that should have been 2.0
- By far the heaviest app we have running within Betty Blocks; can't it be a little smaller?

Summary: I tested different single-sign-on softwares for a project I developed. Then I decided to use this one because it is actively maintained, and it is free :)

Positive: Free.
Great support.
Simple to setup.
Works on Linux.
Ready to work with Google, Facebook, Apple.
Ready for internationalization..

Negative: No possibility to add custom fields.
Integration with WordPress can be improved.

Summary: Very pleased overall with the ability to integrate with my application in areas like user management and authentication via a gateway.

Positive: Documentation is good, public support excellent in promptness and attitude.
Excellent OAuth/OIDC support.
Flexible deployments.
Sufficient lightweight for embedding in cloud-native architectures.

Negative: One complication for me was the lack of support for proxied deployments of the Admin Console. Had to architect around that.

Summary: We needed a good solution for AAA in our micro-service architecture, so we searched a lot and all the solutions were either paid or weak. FusionAuth stood out to be both free and feature-rich.

Positive: We have been using FusionAuth for two years now and we have no complaints. Very stable, occasional updates, good support and most importantly completely free. It also included all the features that we needed.

Negative: The documentations could be better. We had a bit of difficulties at the beginning when we were trying to integrate our system but we figured it out eventually.

Summary: The overall experience is very positive and we would gladly recommend FusionAuth to anyone. The price model is fair and the integration is straightforward.

Positive: FusionAuth is a clean and modern IDP. We found it very easy to integrate our systems with FusionAuth. We used the C# client and the Java client to implement the integration and followed the well-written API documentation.

Negative: Some small bugs here and there but nothing serious. For example, logging in to the FusionAuth web service sometimes fails for no apparent reason and one needs to login again. There are also some hidden configurations that weren't defined in the documentation. For example, if you want a refresh token with the login request then you need to activate that under the preferences and this was a bit elusive for us.
