Convert Experiences vs Kameleoon

Strengths

  • Unlimited experiments and seats, so nobody rations testing to save licence cost.
  • Serious privacy posture with EU hosting and no data resale.
  • Transparent, published pricing.
  • Genuinely good hybrid model — the same experiment can run client- and server-side.
  • Effective anti-flicker implementation.
  • EU hosting with healthcare-grade compliance options.

Limitations

  • Client-side only — no server-side experimentation.
  • No feature-flag capability.
  • Smaller vendor with a modest ecosystem.
  • Smaller market presence outside Europe.
  • Only the entry tier is priced publicly; everything above it is a sales conversation.
  • Fewer third-party integrations than Optimizely.
