The short version

  • Only Deno has a free tier, so it costs nothing to try first.
  • Each has a real cost: Deno egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications; Veriff you pay per verification attempt, not per verified customer, so a confusing capture flow or poor lighting on mobile makes you pay two or three times for one onboarding.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deno

  • Egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications
  • CPU time overage is $0.10/hour on Pro and Builder tiers, adding to costs for compute-intensive workloads
  • Enterprise pricing is not disclosed; requires sales contact

Veriff

  • You pay per verification attempt, not per verified customer, so a confusing capture flow or poor lighting on mobile makes you pay two or three times for one onboarding.
  • The headline $0.80 covers the document and selfie check only; adding PEP and sanctions screening at $0.64 nearly doubles the per-check cost, which is the number regulated buyers actually need.
  • Monthly minimums of $49 and $99 are low but real, so a product with seasonal signup patterns pays in quiet months.
  • Automated decision quality varies sharply by document type and issuing country, so a strong global average conceals weak performance in specific markets you may depend on.
  • Standard data retention is short and extending it to two years is a $0.30 per verification add-on, which matters because most financial regulators require records for five years or more.
