The short version

  • Only authentik has a free tier, so it costs nothing to try first.
  • Each has a real cost: authentik smaller project than Keycloak, with a correspondingly smaller community and fewer integration guides; iDenfy rates are quoted rather than published on an accessible page, so despite the marketing emphasis on transparency you still need a sales conversation to get a number.
  • They diverge on capability: authentik covers Configurable flows, iDenfy covers Document verification.
  • 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.

authentik

  • Smaller project than Keycloak, with a correspondingly smaller community and fewer integration guides
  • The flow model is flexible but conceptually unfamiliar, and simple setups can feel over-abstracted
  • Enterprise support and some governance features sit behind the paid tier
  • Self-hosted identity is still yours to secure, patch and keep available

iDenfy

  • Rates are quoted rather than published on an accessible page, so despite the marketing emphasis on transparency you still need a sales conversation to get a number.
  • It is a smaller vendor than the market leaders, which makes it a harder sell through enterprise vendor-risk review even when the product performs well.
  • Human review on every case caps throughput in a way fully automated competitors are not constrained by, which shows up as latency during volume spikes.
  • Coverage and accuracy are strongest on European documents; performance on some Asian, African and Latin American document types trails specialists in those regions.
  • The bundled AML screening uses its chosen data sources, so institutions mandated to use a specific list provider such as Dow Jones cannot substitute it and end up paying twice.

Answered from the vendors’ own pages

authentik: Is authentik free?

The open-source edition is free and complete for most use. An enterprise tier adds support and additional features.

iDenfy: Is AML screening included in the verification price?

That is the pitch, screening bundled rather than sold as a per-check add-on. Confirm which sanctions and PEP data sources are behind it before you rely on it.

authentik: authentik or Keycloak?

authentik is generally reported as easier to run and administer; Keycloak is more established with a larger community and Red Hat behind it.

iDenfy: Is there a monthly minimum?

iDenfy markets itself as having no monthly minimum, in contrast to competitors charging $49 to $299 a month. Get that in writing in the contract.

authentik: Can authentik protect apps with no login of their own?

Yes. Its application proxy places authentication in front of services that have no built-in authentication.

iDenfy: Where is data processed?

iDenfy is established in Lithuania and processes in the EU, which simplifies GDPR transfer assessments compared with United States-headquartered vendors.
