The short version

  • Only ESLint has a free tier, so it costs nothing to try first.
  • Each has a real cost: ESLint slow performance on large codebases compared to newer tools like Oxlint and Biome; 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.
  • Prices and features above were last checked on 1 September 2026.

  • A mobility platform running age and licence checks at signup with volumes too small for an enterprise contractnot ESLint
  • A regulated firm wanting automated decisions by default but human review on borderline cases, priced explicitlynot ESLint

Where each one falls short

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

ESLint

  • Slow performance on large codebases compared to newer tools like Oxlint and Biome
  • Complexity in configuration from scratch, particularly for TypeScript support
  • Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

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.

$0.80 on Essential or $1.39 on Plus, before add-ons. Sanctions and PEP screening adds $0.64 and ongoing monitoring $0.09 per verification.
