Different approaches

Optimizely is an enterprise experimentation platform. It handles feature flags, server-side testing, and content management across large engineering teams. The price reflects that scope.

CROTool focuses on one thing: getting A/B tests live on your site through Google Tag Manager, measured through Google Analytics 4. No proprietary snippet. No vendor lock-in. No annual contract.

If your team runs client-side A/B tests on marketing pages and e-commerce flows, CROTool does what you need at a fraction of the cost.

When Optimizely is better

  • You need server-side or full-stack feature flagging
  • You run 100+ concurrent experiments across engineering teams
  • You need a content management system alongside testing
  • Enterprise compliance requirements (SOC 2, dedicated support)
