| 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 | From $35/month (B2C Essentials at 500 MAUs); B2B Essentials starts at $150/month at 500 MAUs · free tier: $0/month for up to 25,000 MAUs (B2C and B2B), 1 custom domain (card verification), passwordless, unlimited social connections, 5 Organizations, 1 Enterprise Connection, self-service SSO and SCIM, community support; no credit card to sign up |
| Pricing model | Open source self-hosted (no licence fee); commercial support only via Red Hat subscription bundles | Subscription (tiered by Monthly Active Users, with add-ons) |
| 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. | Development teams under roughly 10,000 MAUs, or B2B SaaS vendors needing Organizations plus a handful of SAML connections who can absorb $150–$2,400/month; also regulated buyers willing to buy at Enterprise for the 99.99% SLA, HIPAA/BAA and FAPI profile. |
| 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 run a high-MAU consumer platform (above ~30,000 B2C MAUs pricing is sales-only), you are a cost-sensitive startup on a steep growth curve exposed to the next-tier-up billing rule, you need predictable spend forecasting, or you are a B2C buyer needing enterprise SAML connections below the Enterprise tier. |

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.
