The short version

  • Only Keycloak has a free tier, so it costs nothing to try first.
  • Each has a real cost: Keycloak requires self-hosted deployment and operational expertise to install, configure and maintain; Trulioo per-check rates vary widely by country and data source, so a blended average from the sales conversation misleads if your volume concentrates in expensive markets.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Keycloak

  • Requires self-hosted deployment and operational expertise to install, configure and maintain
  • No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
  • Clustering and high-availability configurations require additional operational knowledge
  • Community support only; commercial support requires third-party vendors or distributions

Trulioo

  • Per-check rates vary widely by country and data source, so a blended average from the sales conversation misleads if your volume concentrates in expensive markets.
  • Coverage breadth is real but depth is uneven; a country on the map may be served by one thin source with low match rates, which you only discover in a live test.
  • You are charged per query including no-match results, so a market with poor source coverage burns budget producing nothing usable.
  • Because it aggregates third-party data, data residency and consent handling depend on the underlying provider terms, which complicates GDPR assessments in some jurisdictions.
  • Document and biometric capability is competent but not the strongest in the market, so buyers whose primary need is document fraud detection usually pair it with a specialist.

Answered from the vendors’ own pages

Keycloak: What protocols does Keycloak support?

Keycloak supports OpenID Connect, OAuth 2.0 and SAML 2.0 protocols for authentication and authorisation.

Source
Trulioo: Does it need a document?

Not for the core product. Data-source matching uses name, address and date of birth, which is why completion rates are higher than document flows.

Keycloak: Can Keycloak integrate with existing user directories?

Yes. Keycloak supports user federation with LDAP and Active Directory systems, allowing organisations to leverage existing user directories.

Source
Trulioo: Are unmatched queries billed?

Yes, in general you pay per query rather than per successful match. Negotiate this explicitly if you are entering markets with thin coverage.

Keycloak: Is Keycloak free?

Yes. Keycloak is fully open-source and free to deploy and use. No licensing fees are required.

Source
Trulioo: Can it verify companies as well as people?

Yes. Business verification including beneficial ownership is a distinct product line and a common reason to choose Trulioo over document-first vendors.
