Developer-Friendly
What do you dislike about the product?
• Database Portability: We’d like easier migration between MySQL and PostgreSQL—ideally built-in tooling or export/import processes to switch backends without major rework.
• Cloud-Native Monitoring: Integration with modern observability stacks (like Prometheus, Grafana, or OpenTelemetry) would be a big plus for monitoring health and performance in production environments.

Make our product single identity provider system
A generally decent auth provider for devs and enterprises.

Good documentation. Decent, responsive support with multiple channels. Large and exanding featureset. Straightworward integration with any platform supporting OIDC/SAML.
What do you dislike about the product?
Some implementation quirks, though generally easy to deal with using support.
What problems is the product solving and how is that benefiting you?
Unified auth for our platforms and systems for both internal users and customers means that we don't need to roll our own, or manage in multiple places.

- State doesn't go through transactional webhooks
What problems is the product solving and how is that benefiting you?
We're providing SSO to our users for around 4 products. Its really easy to integrate across different products, e.g next-auth supports fusionauth out of the box.
Great team to work with
What do you like best about the product?
We've found FusionAuth to be a great partner. When we were evaluating different products to use for our Authentication stack, we compared FusionAuth with another much larger competitor. We elected to pick FusionAuth because we felt that they would be a better partner and would be more responsive to our issues. We definitely made the right decision in this case. They're very easy to work with, very transparent and very responsive. Their support is top notch.
What do you dislike about the product?
Nothing major. Would be nice if they were able to deliver feature requests more quickly, but that's to be expected.
What problems is the product solving and how is that benefiting you?
We partnered with FusionAuth to deliver a well-supported authentication platform that supported SAML and SCIM.
pleased with FusionAuth
What do you like best about the product?
Self-hosting FusionAuth was a great selling point for us. It's SDK is feature rich and very dev friendly. We've been able to easily integrate FusionAuth into our ecosystem.
What do you dislike about the product?
There were some areas where documentation was a bit sparse and caused us a bit of confusion.
What problems is the product solving and how is that benefiting you?
Out of the box, self-hosted, feature rich identity and access management
Reliable and Developer-Friendly Auth Solution with Great Flexibility
What do you like best about the product?
FusionAuth made it easy to implement secure authentication with minimal friction and maximum control.
What do you dislike about the product?
FusionAuth strikes a rare balance between ease of use and deep customizability. The documentation is thorough, the APIs are well-structured, and the admin UI is intuitive. Unlike many other identity platforms, FusionAuth gives you full control over the user data and the infrastructure — which is invaluable when you need compliance, security, or performance tuning.
What problems is the product solving and how is that benefiting you?
FusionAuth helps us centralize and secure our user authentication system across multiple applications, reducing technical debt and streamlining user management. Before adopting it, we spent considerable time maintaining custom auth logic. Now, we rely on FusionAuth to handle SSO, MFA, and token-based security reliably. It also gives us flexibility to manage user roles and permissions cleanly, while keeping our infrastructure compliant and easy to audit.
Dev-friendly SSO solution
What do you like best about the product?
It's easy to set up SSO across apps. Also really simple to download and run locally, which helps us test new versions before making any changes. The hosted login pages are easy to customize, and the docs are pretty helpful. Their support team is knowledgeable and always ready to help out in different scenarios. We're using it mainly for SSO across our homegrown apps.
What do you dislike about the product?
The Admin UI could be more intuitive. Also, there’s no built-in AWS integration for webhooks, so we’ve had to set that up manually. Would be great if that part was more plug-and-play.
What problems is the product solving and how is that benefiting you?
FusionAuth is helping us manage user authentication across multiple apps in one place. We are able to set RBAC to users logging into our application suite. Support team is really helpful when it comes to tackling different security scenarios around MFA, tokens etc.
Auth Made Simple
What do you like best about the product?
Cost is great and handles everything we need.
What do you dislike about the product?
A lot more config is needed when setting up our applications. It was a little more difficult to get started.
What problems is the product solving and how is that benefiting you?
Fusion Auth is helping us with our centralized auth solution
Robust and super complete user management system
What do you like best about the product?
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.

What do you dislike about the product?
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.

What problems is the product solving and how is that benefiting you?
We use FusionAuth to offer a single point of entry for our users. We provide services that integrate multiple systems and FusionAuth provides the use with an easy way to login to all of those systems. We have thousands of people using our systems so this is a secure and budget friendly solution to easily manage all the users in one central place.
