Compare

Checked against their own documentation.

Each comparison lists the pages we read and the date we read them. Where a product's documentation did not answer a question, the row says "not documented" instead of guessing.

FoxAuth compared with Auth0

Auth0 is a managed identity service billed per monthly active user. FoxAuth is a server you run, with every protocol feature included.

Pick Auth0 if you want identity as a service this week, with social connections and certified FAPI you can hand to a reviewer. Pick FoxAuth if the data must live in your own database, your per-user bill is the problem, or you need the banking-grade profiles without an Enterprise add-on.

FoxAuth compared with Keycloak

Both are servers you run yourself. They differ in runtime, storage, scope and how much of the protocol is on by default.

Pick Keycloak if you need SAML, LDAP federation or certified FAPI today. Pick FoxAuth if your team writes TypeScript, wants OAuth 2.1 behaviour as the default, or wants an AI agent administering the server through the same audited path a human uses.
