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.; IDnow agent-led video identification costs several times an automated check and depends on agent availability, so peak-time queues push abandonment up at exactly the moment conversion matters.
  • They diverge on capability: Clerk covers Prebuilt UI components, IDnow covers VideoIdent.
  • 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.

IDnow

  • Agent-led video identification costs several times an automated check and depends on agent availability, so peak-time queues push abandonment up at exactly the moment conversion matters.
  • Pricing is quoted with an annual volume commitment, so the accreditation advantage comes with a floor you pay whether or not you use it.
  • The product is optimised for European regulatory regimes, so buyers verifying users in North America, Asia or Africa will find coverage and cost less competitive than global specialists.
  • Qualified electronic signature is a separate licence from identity verification, which surprises buyers who assumed the accredited identity check made the signature capability included.
  • Integration for the regulated flows is heavier than a simple SDK drop-in because the compliant journey, including consent and recording requirements, constrains the user experience you can build.

Answered from the vendors’ own pages

Clerk: What does Clerk cost?

Clerk's Hobby plan is free with a 50,000 MRU limit; Pro is $25/month ($20/month billed annually), Business is $300/month ($250 annually), and Enterprise uses custom annual pricing.

Source
IDnow: Why choose it over a cheaper automated vendor?

Because in some European regimes the cheaper vendor is not legally permitted for the transaction. This is an eligibility question, not a quality one.

Clerk: Is there a free plan and what are its limits?

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.

Source
IDnow: Is the electronic signature included?

No. Qualified electronic signature under eIDAS is licensed separately from identity verification.

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.

Source
IDnow: Where is the data processed?

In European data centres, which is a requirement rather than a preference for many of its regulated customers.
