Best Website Optimization Software

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.

Contentsquare is an experience analytics platform that shows businesses how visitors behave on their websites and apps through session replay, heatmaps, and journey analysis. It is built for marketing, product, UX, and ecommerce teams that want to find friction points, quantify their revenue impact, and prioritize fixes without relying only on traditional web analytics.

The platform is sold as a suite covering Experience Analytics, Voice of Customer, and Product Analytics, each with its own pricing tiers. A free plan covers up to 200,000 monthly sessions for one project, while the Growth plan starts at $49 per month ($39 per month billed yearly). Pro and Enterprise plans use custom, sales negotiated pricing.

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.

FullStory is a digital experience analytics platform that helps product, engineering, and support teams understand how users actually interact with their websites and apps. It combines session replay, heatmaps, and automatic frustration detection such as rage clicks and dead clicks so teams can spot friction points without manually tagging every event in advance.

The platform captures behavioral data automatically, letting teams search and segment sessions after the fact rather than defining tracking upfront. FullStory offers a free plan for smaller sites and custom priced Business, Advanced, and Enterprise plans for larger organizations, sold through a sales led process rather than public list pricing.

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.

Omniconvert is a conversion rate optimization platform built around three tools: Explore for A/B testing and personalization, Nexus for AI-driven ecommerce customer intelligence, and Pulse for NPS and customer experience surveys. Explore lets marketing and CRO teams run A/B and split URL tests, build on-site surveys, and personalize content using more than 40 segmentation criteria, with both a visual editor and a code editor for advanced changes.

Explore offers a genuinely free plan covering 50,000 tested users per month with full feature access, not a stripped-down trial. Paid Explore plans scale by monthly tested users through an online calculator rather than fixed public price tiers, and an Enterprise plan adds managed CRO services. Pulse pricing starts free, with an Expert tier at $290 per year.

AB Tasty is a digital experience optimization platform founded in Paris in 2009. It combines A/B and A/B/n testing, a visual WYSIWYG editor, server-side feature experimentation, feature flagging, and rule-based personalization in one platform, letting marketing and product teams test and roll out changes without waiting on engineering for every change.

The platform targets mid-market and enterprise brands such as Kering, McDonald's and L'Oreal, and is used to run web and app experimentation programs. Pricing is fully custom and based on traffic, domains and modules selected, with no published self-serve tiers. Instead of a self-serve free trial, AB Tasty offers a guided one to two week proof-of-concept.

Convert Experiences, marketed as Convert.com, is an A/B testing platform founded in 2008 and built for conversion rate optimization teams and agencies. It supports A/B, split URL and multi-page testing, an advanced goals engine with over 40 stackable targeting filters, free heatmaps on every plan, and a headless API for running experiments outside the browser.

Pricing is based on monthly tested users. The Growth plan costs $399 per month, or $299 per month billed annually, for 100,000 tested users a month. The Pro plan costs $599 per month, or $420 per month billed annually, adding more active projects and goals. Enterprise plans with 1 million or more tested users a month use custom, annual-only pricing. A 15-day free trial requiring no credit card is available.
