Crazy Egg is a website optimization tool founded in 2006 that helps businesses understand visitor behavior through heatmaps, scrollmaps, confetti reports, session recordings and A/B testing. It is aimed at small to mid-sized businesses and includes a visual page editor so non-technical users can create and launch test variants without writing code.

Crazy Egg offers four annually billed plans: Starter at $29 per month for 5,000 tracked pageviews, Plus at $99 per month for 150,000 pageviews, Pro at $249 per month for 500,000 pageviews, and Enterprise at $599 per month for 1,000,000 pageviews. Every plan includes unlimited domains and team members with no overage charges, and a 30-day free trial is available on all plans.

Kameleoon is a Paris-founded experimentation and personalization platform that combines A/B testing, AI-driven personalization and feature management. Its newer offering, Prompt-Based Experimentation (PBX), lets teams generate test variations and audience segments using natural-language prompts instead of manual setup, alongside sequential testing, multi-armed bandits and more than 40 segmentation criteria.

Kameleoon offers a free 30-day PBX trial covering up to 3 experiments with no credit card required. The PBX Starter plan starts at $495 per month for up to 10 experiments and 50,000 monthly tracked users, including sequential testing, SRM detection and Figma integration. Advanced capabilities such as feature management, mobile app testing, a code editor, and full personalization are reserved for the custom-priced Enterprise plan.

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.

VWO, made by Wingify, is an experimentation platform used to run A/B, split, and multivariate tests across websites, mobile apps, and server side systems. It combines a no code visual editor with heatmaps and session recordings built into every test report, Bayesian statistics for interpreting results, and behavior based audience targeting. AI generated optimization ideas and feature level testing round out the platform, and it integrates with major analytics, CRM, and ecommerce tools.

VWO structures pricing around Growth, Pro, and Enterprise tiers based on Monthly Tracked Users, but exact dollar figures are not published on its official pricing page and instead require a custom quote. Its long standing free Starter plan was discontinued as of 2026, with new sign ups now given a 30 day free trial instead. VWO is used by thousands of businesses across more than 90 countries, ranging from growing companies to large enterprise brands.
