More flexibility from a flicker-free and blazingly fast platform. 

  • Kameleoon has no page load impact with a script 2x faster than Optimizely’s. Our Chrome extension quickly reveals the speed performance of each live test. 
  • Kameleoon also has a unique 100% flicker-free engine for all websites. Optimizely prevents flickering with a synchronous tag that drags performance. 
  • Kameleoon’s cross-domain management is compatible with all versions of Safari Intelligent Tracking Prevention (ITP)
  • Kameleoon is the only A/B testing solution to offer a CUPED, which increases reaching statistical significance up to 60% faster, and a Custom Attribution Window, so that brands can accurately (and more quickly) measure the impact of their experiments.

Full Stack testing made easy.

  • Kameleoon HybridTM empowers Growth and Product teams to launch feature experiments independently from Developers’ release cycles.
  • Retrieve audiences from your preferred martech tools and target them in server-side tests and feature experiments without additional coding required.
  • Analyze feature experiment data in real time with built-in client-side reporting.
  • Sync your results to your activation and analytics solutions, without Developers having to code and maintain integrations
  • Optimize targeting with mutually exclusive client-side and server-side experiment logic.

Fast speed, accurate stats, and high security don’t cost extra.

  • Kameleoon correctly handles Apple ITP privacy measures
  • Kameleoon runs on a private cloud, not Amazon Web Services (AWS) or Google. We support single-tenant cloud installations and on-premises deployment options.
