Our notes

The heavyweight choice on purpose: full SAML IdP/SP, an LDAP outpost for legacy apps, 350+ pre-built integrations, and a web UI flow builder instead of YAML. Costs roughly 10x the RAM of Authelia for that — worth it once you are protecting a real number of apps or need SAML specifically.
