Cheaper ways to solve the same problem
What you would be giving up
Keycloak is most often brought in for organisations requiring self-hosted identity infrastructure for compliance or data residency, companies with existing ldap/active directory systems needing federated authentication, open-source projects and communities requiring free iam without licensing costs, enterprises building custom identity workflows requiring fine-grained authorisation, teams with sufficient operational expertise to manage infrastructure. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.
Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.
If Keycloak is broadly right and the question is cost, the Keycloak pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Developer Tools category lists everything the directory holds, and best developer tools tools ranks them.
Keycloak runs on self-hosted, docker, kubernetes, linux, windows, api. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.
