The short version

  • Only Keil MDK has a free tier, so it costs nothing to try first.
  • Each has a real cost: Keil MDK pricing for Essential and Professional subscriptions not disclosed on primary site; 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.
  • 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.

Keil MDK

  • Pricing for Essential and Professional subscriptions not disclosed on primary site
  • Customers must contact Arm Developer Tools store for subscription rates

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

Yes, Keil MDK Community Edition is free for non-commercial projects. Essential and Professional editions are available as monthly or annual subscriptions.

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.

Specific pricing for Essential and Professional editions is not published on the main site. Rates are available from the Arm Developer Tools store or by contacting Arm sales.

Source
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.

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.
