Kameleoon vs ConfigCat

Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Entry price

From $495 per month (PBX Starter: 10 experiments, 50k tested visitors)

Trial only

From $110 per month (Pro)

Free tier

What drives the bill

The metric that actually scales your invoice.

Kameleoon now publishes an entry price. Above Starter it is priced by traffic and modules on a custom quote.

Plans run Free, Pro $110, Smart $325, Enterprise $900 and Dedicated $4,500 a month. Unlimited seats and unlimited flag reads on every plan, including free — unusual and genuinely valuable for wide access; paid tiers mainly raise flag, environment and product limits.

Free tier

30-day trial, no card, up to 3 experiments.

Free forever plan with a monthly config-request allowance and unlimited members.

Strengths

  • Genuinely good hybrid model — the same experiment can run client- and server-side.
  • Effective anti-flicker implementation.
  • EU hosting with healthcare-grade compliance options.
  • Unlimited team members at every tier, so product and support can toggle flags too.
  • Very simple to adopt — an afternoon, not a project.
  • Broad SDK coverage including Dart and Elixir.

Limitations

  • 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.
  • No experimentation or analytics to speak of.
  • Limited targeting sophistication compared to LaunchDarkly.
  • Small vendor.

Best for

European enterprises needing both marketer and developer experimentation under GDPR.

Teams that want simple, cheap flags accessible to the whole company.
