The short version

  • Only Clerk has a free tier, so it costs nothing to try first.
  • Each has a real cost: Clerk pricing scales with monthly retained users, which can grow expensive quickly for consumer apps with large user bases.; 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: Clerk covers Prebuilt UI components, 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.

Clerk

  • Pricing scales with monthly retained users, which can grow expensive quickly for consumer apps with large user bases.
  • Enterprise SSO connections beyond the first are billed as add-ons, adding cost for larger organizations.
  • The Business tier's extra dashboard seats cost $20/month each, which adds up for larger teams.
  • Enterprise-tier features like the 99.99% uptime SLA require annual contracts rather than flexible monthly billing.

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.

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.

Yes, the Hobby plan is free with a 50,000 monthly retained user (MRU) limit per app, up to 3 dashboard seats, and unlimited applications, with no credit card required.

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.

Clerk: How is usage metered?

Clerk meters by monthly retained users (MRUs) — users who return to the app at least a day after signing up — with overage billed at $0.02 per MRU beyond the included 50,000 on paid plans.

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.
