Good Product, Horrible Customer Treatment
What do you like best about the product?
We have complex needs in that we’re a multi-sided, multi-tenant enterprise SaaS platform and need to support customer specific identity providers for SSO. We also require end-to-end authentication across different applications, microservices, and APIs. FusionAuth’s flexible multi-tenant architecture and first-class developer experience enabled us to unify all of this in short order, and made it simpler than others (at the time) to do so.
What do you dislike about the product?
Their commercial practices are horrible. For many years we were a "no maintenance" customer, never needing to leverage their support or complain in any way. At the request of their CEO we let them do a press release about our selection of them. We served as a sales reference too, even speaking with prospects, at least one of which became a customer spending more than double what we did.
Last year, out of the blue, FusionAuth dropped a more than 2x price increase coupled with an annual commitment under the guise of dropping high availability hosting from the plan we were on. We didn't need any of the features in the new tier, either.
Their account executive hounded us relentlessly via email and voice mail, all the while ignoring our request for specifics as to how a downgrade would be handled if we did not proceed. Ironically, their VP of sales would email about "our continued partnership." Meanwhile, their backoffice kept renewing our existing plan, sending mixed messages.
After years of being their advocate, we were left feeling like just another number to squeeze for revenue.

What problems is the product solving and how is that benefiting you?
FusionAuth’s IAM platform was built with developers in mind and is API-first, meaning developers are able to easily integrate its authorization and authentication services such as OAuth, OpenID Connect and SAML directly into the products they're building. At the time we selected them, they were leagues ahead of other competitors like Auth0 in this regard.
FusionAuth improves my productivity while keeping my applications secure
What do you like best about the product?
FusionAuth manages user authentication for my internal and client side applications and what I enjoy the most is how easy it is to set up single sign-on and multi-factor authentication. As once configured, I never have to manage them again. I enjoy the simplicity of the Dashboards and the low frequency of user facing changes.
What do you dislike about the product?
Troubleshooting documentation, and documentation on tweaking some components, is to me overly complex. I also didn’t anticipate the configuration time due to the state of the legacy systems. Further, I feel reluctant documentation around advanced settings and some high level prompts on what is to come would go a long way.
What problems is the product solving and how is that benefiting you?
I can now focus my uncovered time on user facing applications, knowing that the security of user access to back-end applications is stream lined and also since FusionAuth improves compliance around security and manages support requests around blocked accounts.
Solid!
What do you like best about the product?
It's user friendly, offers great flexibility with customizable workflows that are easy to set up & use
What do you dislike about the product?
Nothing so far. I like the software.....
What problems is the product solving and how is that benefiting you?
Mostly login issues,
FusionAuth is My Favorite Authentication Provider for My Apps.
What do you like best about the product?
FusionAuth suited my needs as the authentication system for a number of web applications I use and I particularly like the ease with which I can control different methods of logging in - email/password, social logins, and even magic links. The self-hosted option is particularly appealing because the APIs are simple, and control over the data is guaranteed. I have the freedom of self-hosting without the worry of being stuck in a rigid setup.
What do you dislike about the product?
The admin UI could use some work. It is quite frustrating going through many menus for what should be simple adjustments. It takes a lot longer than it should to set some advanced features like a tenant-specific role or a webhook. Other useful features are paid and can be expensive for smaller projects.
What problems is the product solving and how is that benefiting you?
FusionAuth saves me countless hours on building authentication systems from scratch, which is a significant portion of time wasting effort. It automates user account consolidation, password management, complicated login processes, user sign up and sign in, and user centralization. With authentication systems no longer being an issue, I can dedicate my time on the actual product.
Top-Notch Identity Provider, Top-Notch Support, Minimal Cost
What do you like best about the product?
Have been using FusionAuth as our primary identity provider for a few years now. It's been fantastic. Their documentation is professionally written and well organized - that along with their "Ask AI" feature has made it possible to accomplish some sophisticated configurations to meet our customer needs without having to reach out needlessly for support. Speaking of support... they are very friendly and quick to respond to messages. Various installation methods (managed or self-hosted) and different plan tiers make it quite flexible for various product needs. The starter plan is very generous and compared to other offerings on the market the cost is minimal. Overall I'm very pleased with selecting FusionAuth as our identity provider.
What do you dislike about the product?
Minor gripe, but I would find it helpful to be able to generate more advanced reports on users, usage, sessions, etc from the dashboard directly. Some of the reports I've had to generate in the past were easier to generate by using their API, then writing a quick script to roll-up results. Otherwise, not much to "dislike" about the service - it's frankly been one of the easiest to incorporate into our stack. Very pleased with our decision.
What problems is the product solving and how is that benefiting you?
We needed an affordable way to implement multi-tenancy in a B2B scenario, are were particularly interested in the "Identity Provider" support so we could offer customized SSO for each tenant individually. Achieving this with competitors would be possible, but at significant cost. The primary benefit to FusionAuth for our team has been the ability to fully isolate tenants and configure them to meet varying customer needs. Furthermore, their API has made it possible to automate much of the provisioning and deprovisioning of tenants, users, and other bits of configuration.
Finally, our team can build features, not just endlessly manage user logins
What do you like best about the product?
What we truly like is that it is quite seamless to utilise several separate client environments with only a single FusionAuth instance. The flexibility of the theming of our online onboarding process of new B2B customers has allowed us to add a branded login experience without any glitches. We also found the custom data fields so helpful in assigning specific fields of data to user profiles, in order to drive some of our internal analytics.
What do you dislike about the product?
The configuration settings that are not used often, at times, are a little less transparent to navigate the console. We also would have liked to see an easier way to export/import whole application setups between our development and production servers. There was also a steep learning curve to using some of the advanced webhook event triggers, although this got easier as time went on.
What problems is the product solving and how is that benefiting you?
We found it very difficult to offer different branded identity experiences to each of our B2B clients, and then have a single user database. Previously to FusionAuth it could take weeks of custom development to implement a new customer inviting them to use a customized portal into their company and managing their user account. Once, it takes weeks to spin up a new client tenant with its own branding, and user roles, now it only takes a matter of hours. It has turned onboarding client workflows into a fast repeatable procedure.
FusionAuth: A flexible identity platform that simply works well and is reliable.
What do you like best about the product?
What I like most about FusionAuth is its flexibility. It’s really intuitive to set up. I’m not a full-time developer, but I’m pretty sure I can configure logins, SSO, and integrations in a much easier way without spending days reading documentation. Fine-grained customization allowed me to form the login experience around my company’s brand perfectly, a process that other avenues made extremely cumbersome. It feels like the control is with me and not that I require external consultants.
What do you dislike about the product?
The main drawback is the learning curve once you want to go beyond the basics. Some of the more advanced workflows, such as complex triggers or esoteric identity provider integrations, take a bit of trial and error. Also, while being more approachably priced than Auth0, the add-ons can add up if you’re not careful.
What problems is the product solving and how is that benefiting you?
Earlier, we were trying to patch homegrown login systems together with each other as well as with third-party solutions that didn’t speak to each other. This was creating these huge security holes as well as friction for the user. Every one of our sales, support, and engineering teams use the same platform to authenticate and track their interactions.
Identity Management That Fits Your Business and Works for Developers.
What do you like best about the product?
The flexibility and developer-friendliness are my favorite things about FusionAuth. It can be a real challenge to configure multi-step authentication processes when you’re not a full-stack security engineer; however, it is enough to get it done in a few simple tweaks due to the existing functionality and lucid documentation. I hardly ever need anything that’s not already onboard, but if I do, the API is robust enough to not struggle to hammer it into other systems.
What do you dislike about the product?
Indeed, the depth of the system might be overwhelming for a novice, and it will take some time to get accustomed to the functionality before all settings are configured properly. Comparing it with Auth0 or Okta, it is reasonably priced, though some advanced enterprise features may feel expensive for a micro-enterprise. More so, file limits concerning logs, and event data may also prove a limitation in case you would want to archive an extensive history.
What problems is the product solving and how is that benefiting you?
FusionAuth centralized identity and access management so there are no more scattered authentication systems for different applications. We’ve reduced our risks by using fine-grained role and permission settings and the integration of our external systems means less time building one-off login solutions. Provisioning real-time insights into user activity enhances accountability while avoiding repetitive provisioning tasks for my team due to the automation of most workflows by this system.
Solid authentication solution that scales well with growing projects!
What do you like best about the product?
It gives me full control over user management without forcing me into a specific workflow. The documentation is clear and the admin dashboard is easy to navigate. I like that it supports multiple authentication methods like OAuth, SAML, and passwordless so I can adapt it for different clients.
What do you dislike about the product?
The initial setup takes some patience especially if you are hosting it yourself. Some advanced configurations feel a bit buried in the settings.
What problems is the product solving and how is that benefiting you?
I needed a way to handle logins and registrations securely across multiple apps without building everything from scratch. FusionAuth let me plug in robust authentication quickly while keeping user data safe. It’s saved me a lot of development time and reduced maintenance headaches.
A Huge Time-Saver That Let Us Ditch Our Legacy Auth Stack for Good
What do you like best about the product?
What I love most about FusionAuth is that it let us centralize our authentication and user management without having to build everything ourselves. We had dozens of apps with fragmented login flows, and FusionAuth helped us unify them under a single, secure system. The React SDK and robust API support made integration surprisingly smooth—even with some of our older applications.
What do you dislike about the product?
The hosted UI felt limiting at times—we had some very specific customization needs that were hard to implement using their pre-built components. Also, while the docs are good overall, searching for advanced implementation details (like how IDs behave in multi-tenant setups) can be frustrating. It’s not as intuitive for smaller teams or startups that are just getting familiar with complex IAM concepts.
What problems is the product solving and how is that benefiting you?
We’re a small team, and just couldn’t afford to spend months building features like MFA, SSO, or role-based access—FusionAuth gave us all that out of the box. And compared to when we were evaluating Okta, FusionAuth felt more developer-friendly and less expensive to scale with, especially for a startup like ours.
