Summary

FusionAuth is a Customer Identity and Access Management server for authentication, authorization, and user management. It supports username and password login, identity providers, passkeys, and one-time passwords, and implements OAuth 2.0, OpenID Connect, and SAML v2. Social identity providers include Apple, Facebook, Google, and Twitter. Teams can customize pages and messages, and use lambda functions and webhooks. Authorization includes role-based controls across users, roles, groups, applications, and entities, with fine-grained authorization integration. FusionAuth can run locally, on-premises, in private or air-gapped cloud environments, or as a managed FusionAuth Cloud instance. Its free Community Edition is self-hosted, unlimited, and has no trial clock. Paid Starter costs $162.00 per month when billed annually and lists one connector and 100 machine-to-machine entities. FusionAuth is intended for managing end users at scale; it does not offer native desktop integration or position itself as an Active Directory replacement.
