Optimizely is an enterprise digital experience platform combining web experimentation and feature flagging with content management and commerce tools. Its experimentation products support A/B and multivariate testing through both a visual editor and code based flag rules, backed by a statistical Stats Engine, audience targeting, and personalization. The platform serves both client side and server side testing, and recent additions include AI powered agentic experimentation and content tools.

Optimizely does not publish fixed pricing tiers online. Every plan is individually packaged around traffic volume, selected products such as Content Cloud, Commerce Cloud, and experimentation tools, and deployment model, with pricing available only after a sales consultation. This custom, contract based pricing model means the platform is generally suited to agencies and larger enterprises rather than small businesses or individuals working with a self serve budget.

Dynamic Yield is an enterprise personalization and experimentation platform used by large brands to tailor web, app, email and offsite experiences in real time. Its AdaptML decision engine combines machine learning models for next-item prediction, intent profiling and visual similarity to power product recommendations, and the platform also supports classic A/B testing, multi-armed bandits and affinity-based allocation. Dynamic Yield has been owned by Mastercard since 2022.

Dynamic Yield does not publish self-serve pricing tiers or a public pricing page. Costs are quote-based and depend on factors such as traffic volume and the number of active tests or personalization campaigns, and prospective customers must contact sales for a proposal. No free trial or free plan is offered.
