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.; Signicat national eID scheme fees are passed through on top of Signicat's own charge, so a single-country business almost always pays less by integrating with the scheme directly.
  • They diverge on capability: ConfigCat covers Feature flags and configuration, Signicat covers eID scheme brokering.
  • 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 Signicat
  • Decoupling deployment from release with percentage rollouts and a kill switch, without buying an experimentation platformnot Signicat
  • A small team that needs ten flags permanently and can run indefinitely on the free tiernot Signicat

  • A public sector body needing cross-border recognition of notified eID schemes under eIDASnot 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.

Signicat

  • National eID scheme fees are passed through on top of Signicat's own charge, so a single-country business almost always pays less by integrating with the scheme directly.
  • Value is concentrated in Northern and Western Europe, and coverage in Southern and Eastern Europe is thinner, so a pan-European rollout still hits gaps requiring document fallback.
  • Pricing is per transaction and quoted, and because scheme rates vary by country the cost per onboarded customer differs materially between markets in ways that complicate unit economics.
  • Each eID scheme connection typically carries its own setup fee and approval process, so adding a country is a project with a lead time rather than a configuration change.
  • Availability is tied to the national schemes, meaning an outage at BankID or MitID stops your onboarding entirely and there is no vendor-side mitigation for it.

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.

Signicat: Is this an alternative to a document verification vendor?

Only where national eID exists. In markets with a mature bank ID scheme it is better; elsewhere you fall back to document checks, which Signicat also provides.

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.

Signicat: Do we still pay the eID schemes?

Yes. Scheme fees are passed through in addition to Signicat charges. Ask for the split when comparing to a direct integration.

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.

Signicat: Are signatures legally qualified?

Signicat supports eIDAS qualified electronic signatures, which carry the highest legal standing in the EU, as well as advanced signatures.

ConfigCat: How fast does a flag change take effect?

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