European alternatives to Auth0
European companies mapped as alternatives to Auth0. Each carries an evidence-led sovereignty profile — jurisdiction, hosting, US exposure, DPA and more — reviewed by SovEU. Profiles are descriptive, not a compliance verdict.
3 alternatives
Open-source identity and access management (SSO, OIDC, SAML), a CNCF project sponsored by Red Hat; self-hostable.
Open-source identity provider (SSO, OIDC, SAML) by Authentik Security; widely self-hosted within Europe.
Open-source identity infrastructure operated by ZITADEL (CAOS Ltd) in Switzerland; available as self-hosted or cloud.
Compare side by side
The same evidence-led signals across each alternative. A blank cell (“—”) means the signal isn't recorded — never a negative claim — and the score is a transparent signal score, not a compliance verdict.
