FusionAuth is a web-scale identity, access, and user management platform that is 100% free for unlimited users.
Built for developers, it deploys in minutes on any platform including Linux, Mac and Windows. It can be used locally during development and deploy on any server (real or virtual), anywhere in the world. FusionAuth also provides Docker and Kubernetes deployments for container based deployments. If you prefer to let FusionAuth host for you, it can be deployed in the FusionAuth private cloud. This means that your user data is never mixed with anyone else's.
FusionAuth provides all of the features any application needs. These include login, registration, SSO, MFA, social logins, authorization, email templates, email verification, forgot password handling, reporting, analytics, user search, user segmentation, a complete, web-based user management UI, groups, roles, federated login, support for multi-tenant applications, Webhooks, Kafka integration, CleanSpeak integration (profile profanity filtering), discipline, and much more.
Unlike other solutions, FusionAuth isn't restricted to a cloud-hosted deployment. This provides better security and compliance with laws that require user data to be stored in specific locations (in country, specific data-centers, etc). With FusionAuth's flexible SLA, you can ensure that your login and registration never go offline and your users can access your application 24/7.
If you need help with integration or new features built, FusionAuth provides professional services to assist you.
