| Pricing | Not published · free tier: Entire community edition is free to download and self-host; no plan ladder, no per-user or per-MAU metering | Starter from $162/mo (billed annually, at the page default of 1,000 MAUs), community-forum support only, basic hosting included · free tier: Community — free, unlimited, self-hosted with core authentication features and community support (forums, Slack, GitHub); passkeys/WebAuthn and biometrics reportedly require registering a free Community licence |
| Pricing model | Open source self-hosted (no licence fee); commercial support only via Red Hat subscription bundles | Subscription (MAU-based tiers; free self-hosted Community edition) |
| Best for | Organisations with in-house platform/DevOps and Java/Kubernetes skills that want to run identity as infrastructure — especially high user volumes where per-MAU SaaS pricing dominates the budget, air-gapped or data-residency deployments, teams needing deep customisation, and existing Red Hat OpenShift Platform Plus, Application Foundations or Red Hat SSO customers. | Engineering-led B2C or mid-market B2B SaaS teams that need data sovereignty or on-prem CIAM, are comfortable with OAuth2/OIDC concepts, and want an API-first platform they can start free and later move to managed hosting without switching vendors. |
| Avoid if | You have no dedicated ops capacity to absorb upgrade breakage, need a published self-serve price and formal SLA for vendor support, rely on non-technical administrators who need an intuitive console, need mature access certification and entitlement reviews in production today, or require a large verified public review corpus for procurement. | You lack dedicated engineering capacity for identity work, require a truly open-source core, need 24x7 support or an SLA on a small budget, need cheap SCIM provisioning, or require FedRAMP or Zanzibar-style fine-grained authorization. |

A higher TOP SCORE means more of the evidence favours that platform on this methodology — it is not a recommendation, and it does not account for your specific requirements. Advertisers are never declared the winner of a comparison.
