FusionAuth vs Google Cloud Identity

FusionAuth is a Customer Identity and Access Management server for authentication, authorization, and user management. It supports username and password login, passkeys, one-time passwords, and external identity providers, including Apple, Facebook, Google, and Twitter. It implements OAuth 2.0, OpenID Connect, and SAML v2. Authorization includes role-based access across users, roles, groups, applications, and entities, plus fine-grained authorization integration. Teams can customize pages and messages and use lambda functions and webhooks. It can run locally, on-premises, in private or air-gapped cloud environments, or as a managed FusionAuth Cloud instance. The free Community Edition is self-hosted and unlimited, with no trial clock. Starter costs $162 a month billed annually and includes one connector and 100 machine-to-machine entities; Essentials and Enterprise cost $2,970 a month billed annually. FusionAuth supports Android, iOS, Linux, macOS, Windows, web, and API deployments.

Google Cloud Identity centrally manages users and groups as an Identity as a Service solution. It can federate identities between Google and providers such as Active Directory and Microsoft Entra ID, and provides single sign-on to thousands of SaaS applications, including Salesforce, SAP SuccessFactors, and Google Workspace. MFA choices include push notifications, Google Authenticator, Titan Security Keys, security keys, backup codes, SMS, voice calls, passkeys, and other TOTP code generators. Its console manages Android, iOS, and Windows devices, with tools to enforce policies, wipe company data, deploy apps, and view reports. Automated provisioning can create, update, or delete user profile information in third-party cloud applications. Directory Sync extends Active Directory users to the cloud, while Secure LDAP supports traditional applications and infrastructure. Free includes 50 user licenses by default; additional licenses can be requested at no cost. Premium costs $6 a month on an annual fixed-term plan, or $7.20 a month on a flexible plan billed monthly. Premium also lists a 99.9% SLA and 24x7 chat and email support.
