How it works

The platform covers web experimentation, feature experimentation for apps and services, and content management, so a large organization can run its whole testing and rollout program in one place. It also offers strong analytics, program management, and integrations with the rest of the enterprise stack.

Optimizely does not publish prices and offers no free plan. Pricing is custom and quoted by the vendor, typically on an annual enterprise contract. It is built for large companies with dedicated experimentation teams, not for small sites that need a quick A/B test.
