OneLogin vs Keycloak

Keycloak and OneLogin are both open source iam solutions. Keycloak open-source IAM platform with SSO, identity brokering, and fine-grained authorization, while OneLogin cloud IAM platform with SmartFactor Authentication and cost-effective pricing. The best choice depends on your organization's size, technical requirements, and budget.

Choose Keycloak if completely free — no licensing costs regardless of user count is your priority and organizations with engineering expertise that want full control over their identity platform, avoid vendor lock-in, and eliminate IAM licensing costs. Choose OneLogin if more affordable than Okta with comparable core SSO and MFA capabilities matters most and mid-market organizations looking for a full-featured cloud IAM platform at a lower price point than Okta with straightforward deployment.

Keycloak starts at Free (open source) / Red Hat Build of Keycloak via subscription (open source + enterprise subscription). OneLogin starts at SSO $2/user/mo; Advanced $4/user/mo; Professional $8/user/mo (per-user tiers). As always, the sticker price only tells part of the story. Factor in add-ons, implementation costs, and what's actually included at each tier.

It depends on how deeply OneLogin is embedded in your stack. Most teams run both in parallel for a few weeks before cutting over. Check whether Keycloak supports importing your existing configs or policies. That's usually the biggest time sink.
