Auth You Can Actually Own
Most auth platforms make you choose: get something developer friendly and hand over your user data, or self-host something open source that takes six months to cobble together.
Community Edition is the same core product our customers run in production; packaged up, free to download, and yours to deploy on your own infrastructure. No trial clock and you get a full identity platform that runs on your laptop, your Kubernetes cluster, your private cloud, or honestly, the server under your desk.
What You Get
Core authentication standards and features like login, registration, SSO, social logi, and basic MFA
Built for developers with full REST API, webhooks, Lambdas, SDKs and quickstarts are 20+ frameworks
Deploy auth anywhere and own your data
Access to the FusionAuth developer community written for devs, by devs
Ongoing product updates, patches, and security fixes
What Users Are Saying
Trusted by 15+ million developers
With FusionAuth, all plans, you can keep adding as many Identity Providers as you want at no extra cost - this was our main issue with other CIAM providers as they demand increasingly unreasonable fees

We were using Auth0 before FusionAuth and, although it had great features, it could be a bit confusing, mainly when talking about roles, scopes, permissions etc. At scale, Auth0’s pricing was outrageous.
Danilo Polani
Senior Software Engineer @ WeRoad
The implementation is so much more intuitive than Auth0. I can run it on my own infrastructure and out of the box it supports everything I need. And more!

The FusionAuth team has been extremely helpful. They really give you the attention you need to solve any identity challenge.

FusionAuth is an amazing product. Tons of features and the support is the best in the industry.

I achieved in a single day's work what took a week and a half with Gluu. FusionAuth is just that simple to use.

It's a huge win for us that we can self-host FusionAuth. Not only do we have extremely low latency for API calls, but also no rate limits. We were previously with Auth0 and their APIs and UIs were rate limited. This often made them horrifically slow.

Why the Email?
Fair question! Two reasons–one, we send the download link there. Two, when there’s a critical CVE or major release, we want to be able to tell you. The Community Edition is still 100% free, unlimited, and yours to host. We just want to provide you with the best FusionAuth experience possible.
