The short version

  • Each has a real cost: GNAT Pro no pricing published on website; requires contacting AdaCore directly for quotes; 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.
  • 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.

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

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

GNAT Pro: How much does GNAT Pro cost?

GNAT Pro pricing is not published on the website. Customers must request a pricing quote by contacting AdaCore directly or speaking with a GNAT Pro expert.

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.

GNAT Pro: What is GNAT Pro licensing model?

GNAT Pro is sold on a per-user, per-year basis with no license locks. Customers can request pricing for their specific needs.

Source
IDnow: Is the electronic signature included?

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

IDnow: Where is the data processed?

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