The short version

  • Only Ory Kratos has a free tier, so it costs nothing to try first.
  • Each has a real cost: Ory Kratos headless means you build every screen, which is significant work compared with a hosted login page; 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.
  • They diverge on capability: Ory Kratos covers Headless API, Trulioo covers Person match.
  • 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.

Ory Kratos

  • Headless means you build every screen, which is significant work compared with a hosted login page
  • More moving parts than a monolithic IAM: Kratos handles identity, and OAuth2 needs Ory Hydra alongside
  • Documentation assumes real familiarity with identity concepts and is not a gentle introduction
  • Self-hosting identity carries the security and availability burden that hosted providers absorb

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

Ory Kratos: Is Ory Kratos free?

Yes, open source and free to self-host. Ory Network is a paid managed service.

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.

Ory Kratos: What does headless mean here?

Kratos provides identity flows as APIs and no user interface. You build the login, registration and recovery screens yourself.

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.

Ory Kratos: Does Kratos do OAuth2?

No. Kratos handles user identity; OAuth2 and OpenID Connect provider functionality is Ory Hydra, a separate component.

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.
