Tool profile
Experimentation and digital experience platform for testing, personalization, and feature delivery.
Global brands running always-on conversion test programs
Optimizely is an enterprise digital experience vendor combining experimentation, personalization, content, and commerce after years of acquisitions.
optimizely.com/pricing (March 2026) does not publish standard per-seat USD cards. Instead it lists product pillars—Content Marketing Platform, Web Experimentation, Analytics, Configured Commerce, Data Platform, CMS, Feature Experimentation, and Personalization—each linking to Request pricing forms. Buyers should expect annual contracts, impression or event metering, seat bundles, and often services-heavy implementations.
For budgeting, triangulate with Statsig, LaunchDarkly experiments, GrowthBook, and Split quotes using the same traffic and flag footprint you will run in production.
