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.; TeamCity detailed pricing requires visiting a calculator and isn't transparent on the main pricing page.
  • They diverge on capability: ConfigCat covers Feature flags and configuration, TeamCity covers Build Chains.
  • 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.

TeamCity

  • Detailed pricing requires visiting a calculator and isn't transparent on the main pricing page.
  • Self-hosted setup and agent management require more operational overhead than fully managed CI/CD services.
  • Additional build agents and users are priced incrementally, which can add up for larger teams.
  • The UI and configuration model have a steeper learning curve compared to YAML-first CI tools.

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.

TeamCity: How much does TeamCity cost?

TeamCity offers a free download option but specific pricing for commercial use is not detailed on the website. Customers must contact JetBrains for licensing and pricing information.

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.

TeamCity: Is TeamCity free to use?

TeamCity has a free option available for download, but full pricing and licensing details require contacting JetBrains directly.

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.

ConfigCat: How fast does a flag change take effect?

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