If you're a developer looking for an alternative to Auth0, you may be wondering which platform to choose. Auth0 may be sufficient for those looking to set up basic authentication with UIÂ form templates. But once you start needing advanced authentication features (like passkeys, multi-factor authentication, and single sign on among others) or support from actual authentication engineers, Auth0 starts to become less-developer friendly.
FusionAuth is different. We're built by developers, for developers. FusionAuth's API and SDKs let you customize your user login experience without compromising on security. You can deploy in any infrastructure and works with any codebase.
FusionAuth has the secure features you expect from your auth solution. Plus everything you'll need to go from beautiful login forms to complex auth scenarios.
Flexibility and control over hosting for
customer private data is a critical
difference.
At Auth0, your data is on a shared server with other Auth0 customers.
With FusionAuth, you can either self-host in your infrastructure or FusionAuth will host on a dedicated server within AWS.
Scale auth without busting your budget. Â
Auth0 pricing is complex and costs continually rise as features are deployed.
At each level, FusionAuth includes all plan features and cost scales solely on volume. Â And only FusionAuth offers a free tier with truly unlimited volume.
FusionAuth makes it easy to your hardest technical questions answered. Â
FusionAuth is an engineering centric company with experienced authentication engineers providing first line technical support.
On our Enterprise plan you even get a dedicated Slack channel for 1:1 questions, migration and architecture support.

Auth0 and Okta are both Identity-as-a-Service (IDaaS) providers that offer cloud-based solutions for authenticating and authorizing users across applications and services.
Auth0 is designed to be an identity platform that enables developers to quickly and easily add authentication and security to their applications, regardless of the technology stack being used. Auth0 provides features such as social login, multi-factor authentication, and password management.
Okta, on the other hand, has a broader focus and offers a comprehensive suite of identity management and access control tools for enterprises. Okta's platform provides a range of services, including single sign-on (SSO), multi-factor authentication, API access management, and lifecycle management for user accounts. Okta offers integrations with a large number of applications and services and has tools for managing user identities at scale.
In 2022, Okta acquired Auth0. While they initially indicated that Auth0 will remain a standalone product, they have recently integrated it into the Okta Customer Identity product. What that means is that developers are seeing their prices increase, more complicated support tiering that is less-than-helpful and other "corporate synergies" that aren't as developer-friendly.
One user on G2 left a review for Auth0 saying that the "new pricing models doubled the price for a reduction in service consumption. Was bullied on meeting 20-day window to accept the offer or leave service.....there will be no further business personally with this company nor their parent Okta." Developers are now exposed to the cost structures of Okta, which could be higher than what they have been accustomed to before.
