The short version

  • Only ConfigCat has a free tier, so it costs nothing to try first.
  • Each has a real cost: ConfigCat there is no experimentation or statistical analysis engine, so teams wanting real A/B tests with significance testing must buy and integrate a separate analytics or experimentation product.; 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.
  • They diverge on capability: ConfigCat covers Feature flags and configuration, Veriff covers Document verification.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

  • A team that wants every engineer, product manager and support agent to have a login without paying per seatnot Veriff
  • Decoupling deployment from release with percentage rollouts and a kill switch, without buying an experimentation platformnot Veriff
  • A small team that needs ten flags permanently and can run indefinitely on the free tiernot Veriff

  • A crypto exchange that needs a published rate to model unit economics before committing to a KYC vendornot ConfigCat
  • A marketplace verifying sellers in dozens of countries where a single document library matters more than depth in one marketnot ConfigCat
  • A mobility platform running age and licence checks at signup with volumes too small for an enterprise contractnot ConfigCat
  • A regulated firm wanting automated decisions by default but human review on borderline cases, priced explicitlynot ConfigCat

Where each one falls short

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

ConfigCat

  • There is no experimentation or statistical analysis engine, so teams wanting real A/B tests with significance testing must buy and integrate a separate analytics or experimentation product.
  • Pricing by flag count punishes exactly the hygiene you want: the Pro tier caps at 100 flags, so teams that do not aggressively retire stale flags are pushed to the 325 dollar Smart tier for housekeeping reasons rather than growth.
  • The free tier allows only 2 environments, which does not cover the common development, staging and production split, so almost any real deployment starts on a paid plan.
  • It is a smaller vendor than the category incumbents, so enterprise procurement teams will find less depth in compliance attestations, contractual terms and reference architecture than LaunchDarkly offers.
  • Flag evaluation relies on SDK-side caching of a CDN-delivered config, which is fast but means propagation of a change is eventually consistent rather than instant, something to understand before relying on it as an emergency kill switch.

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.

Answered from the vendors’ own pages

ConfigCat: How is ConfigCat priced?

By feature flag, environment and product count. Seats, monthly active users and flag reads are unlimited on every plan.

Veriff: What does a verification actually cost?

$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.

ConfigCat: Is the free tier usable?

For small projects yes, but at 10 flags and 2 environments it will not cover a dev, staging and production setup.

Veriff: Are failed attempts charged?

Sessions are charged, so retries by the same user generally cost you again. Ask for the exact billing definition of a session before signing.

ConfigCat: Can it run A/B tests?

It can split traffic, but there is no statistics engine. You need a separate analytics tool to decide a winner.

Veriff: How long is data retained?

The default retention period is short and two-year extended retention is a paid add-on at $0.30 per verification, which is worth checking against your regulatory record-keeping obligations.

ConfigCat: How fast does a flag change take effect?

SDKs poll and cache, so changes propagate on the polling interval rather than instantly.
