The short version

  • Each has a real cost: Burp Suite the automated vulnerability scanner is Professional only, at $499; the free Community edition is manual tools; 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.
  • They diverge on capability: Burp Suite covers Web vulnerability scanner, ConfigCat covers Feature flags and configuration.
  • 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.

Burp Suite

  • The automated vulnerability scanner is Professional only, at $499; the free Community edition is manual tools
  • BApp Store extensions require the Professional edition
  • DAST and the agentic testing product are separate enterprise offerings with no published price
  • Professional is licensed per user per year rather than perpetually

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.
