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.; TrustArc the software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • They diverge on capability: ConfigCat covers Feature flags and configuration, TrustArc covers Nymity Research.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

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

ConfigCat

  • A consumer or mobile app with millions of users where per-MAU flag pricing would cost more than the flags are worthnot TrustArc
  • A team that wants every engineer, product manager and support agent to have a login without paying per seatnot TrustArc
  • Decoupling deployment from release with percentage rollouts and a kill switch, without buying an experimentation platformnot TrustArc
  • A small team that needs ten flags permanently and can run indefinitely on the free tiernot TrustArc

TrustArc

  • A consumer brand that needs an independent privacy seal on its website because enterprise customers or app stores ask for third-party verificationnot ConfigCat
  • A multinational privacy team that needs a maintained answer to what a given jurisdiction requires without retaining outside counsel for every questionnot ConfigCat
  • An organisation running DPIAs at volume that wants templates tied to a maintained regulatory library rather than to a consultant word documentnot ConfigCat
  • A privacy programme being audited that needs documented maturity benchmarking against a recognised framework of programme activitiesnot 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.

TrustArc

  • The software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • The integration catalogue is smaller than the market leader, which means more of the data inventory is maintained by hand and drifts out of date between reviews.
  • Certification services are sold separately from the platform subscription, so the seal that is often the reason for choosing TrustArc is an extra line item and an extra annual renewal.
  • Reported contract values vary enormously by module mix and organisation size, and the absence of published pricing means smaller buyers have no anchor and routinely discover the entry price is higher than expected.
  • TrustArc stays inside privacy, so organisations that later want third-party risk, security compliance or ethics reporting on the same platform will be running a second vendor anyway.

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.

TrustArc: What does TrustArc have that OneTrust does not?

Nymity Research, a maintained regulatory intelligence library acquired in 2019, and the TRUSTe third-party certification and seal programme.

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.

TrustArc: How much does TrustArc cost?

Not published. Reported enterprise agreements range widely depending on modules and organisation size, and certification services are quoted on top of the platform subscription.

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.

TrustArc: Is TRUSTe the same company?

Yes. TrustArc is the renamed TRUSTe business and still operates the TRUSTe certification programme as a subsidiary.

ConfigCat: How fast does a flag change take effect?

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

TrustArc: Does it handle cookie consent for Europe?

Yes, it includes a consent manager with scanning and banner delivery, though pure-play consent vendors are cheaper if that is all you need.
