The short version

  • 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.; Statsig pro plan is limited to a single project, requiring Enterprise for multi-project support.
  • They diverge on capability: ConfigCat covers Feature flags and configuration, Statsig covers Feature Flags.
  • Prices and features above were last checked on 31 August 2026.

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.

Statsig

  • Pro plan is limited to a single project, requiring Enterprise for multi-project support.
  • Overage pricing on the Pro plan can become costly for high-event-volume products.
  • Warehouse-native deployment and advanced access controls are gated behind custom Enterprise contracts.
  • Free tier session replay and analytics retention are capped, pushing active teams toward paid tiers quickly.

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.

Statsig: What does Statsig cost?

Statsig offers a free Developer tier, a Pro tier at $150/month with 5M included events and $0.05 per 1,000 events after that, and custom Enterprise pricing based on event or experiment volume.

Source
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.

Statsig: Is there a free plan, and what are its limits?

The free Developer plan includes 2M events per month, unlimited flag and config checks, 50,000 session replays per month, and 1-year analytics data retention with unlimited seats.

Source
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.

Statsig: How is usage metered on Statsig?

Statsig meters billable events including exposures with Metric Lifts enabled, log events from SDKs or imports, ingested warehouse metrics, and custom metrics; disabled flag checks are not metered.

Source
ConfigCat: How fast does a flag change take effect?

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