7 Best Website Personalization Software Tools in 2026

Many websites still show every visitor the same homepage, whether they arrived from a pricing ad, a blog post or a cart reminder. Website personalization software changes that by swapping content, offers and product recommendations based on who the visitor is and what they have done. The tools below differ mainly in where they come from: some started in A/B testing and added personalization, others started in ecommerce recommendations and added testing.

What website personalization software does

• Targets audiences. Segments by source, behavior, location, device or CRM data.
• Changes the experience. Banners, hero sections, navigation, offers and product recommendations.
• Tests the change. A/B or multivariate tests, or bandits that shift traffic to the winner.
• Uses AI. Many tools now use AI to suggest audiences, generate variants or pick the best experience per visitor.

Good first projects are the ones where the audience is easy to define and the outcome is easy to measure:

• Returning visitors: replace the generic hero with the category or product they viewed last time.
• Campaign landing traffic: keep the headline and offer consistent with the ad or email that brought the visitor in.
• Known customers: hide the first-order discount from people who have already bought and show a loyalty or referral prompt instead.
• Industry or company size (B2B): swap logos, case-study topics and calls to action to match the visitor's segment.

Measure each against a holdout group that still sees the default page. If a personalized experience does not beat the default for its audience, switch it off; every extra variation is something your team has to keep up to date.

A note on a tool you may remember: Google Optimize has not been available since September 30, 2023, so it is no longer an option. Personalization on the site also works best when it matches the messages people receive elsewhere; our guide to real-time personalization in customer engagement covers that side.

How we picked these tools

Each tool had to personalize website experiences for different audiences (not only run A/B tests), be sold to new customers in October 2026, and describe the capability on its own site. We read each description and any published price on the vendor's own site in October 2026. Because most vendors in this category quote prices, we say so where that is the case. We did not run paid trials.

At-a-glance comparison

The best website personalization software

1. Optimizely: experimentation-led personalization

Optimizely runs no-code web experiments with a visual editor or server-side tests, including multivariate tests and bandits, and uses behavioral data and experiment results to show the right experience to each audience. Its personalization uses AI agents that find opportunities and stage campaigns.

Pricing (as of October 2026): Optimizely says every plan is individually packaged. Strengths: rigorous testing behind every personalized experience, plus a CMS from the same vendor. Limits: no public pricing and an enterprise sales process.

2. Dynamic Yield by Mastercard: personalization for commerce

Dynamic Yield's website now redirects to Mastercard, and its Experience OS connects personalization, discovery, recommendations, messaging, testing and analytics in one system. It personalizes recommendations, content and messages across web, app, email and SMS, with industry versions for ecommerce, grocery and travel.

Pricing (as of October 2026): not published. Strengths: deep product recommendation algorithms for catalogs. Limits: no published pricing or self-serve plan.

3. Wingify (VWO and AB Tasty): from testing to personalization

VWO and AB Tasty now sit together under Wingify, which sells separate plan families for web experimentation and web personalization. Personalization comes in Growth (for small teams getting started), Pro and Enterprise plans.

Pricing (as of October 2026): plan tiers are listed on the Wingify pricing page; prices were not displayed when we checked. Strengths: a Growth tier aimed at smaller teams, and testing and personalization from one vendor. Limits: prices are not shown publicly.

4. Kameleoon: AI-built experiments

Kameleoon offers experimentation and personalization with Prompt-Based Experimentation (PBX), which lets you build test-ready variants of any page by chatting with its AI instead of coding.

Pricing (as of October 2026): a free trial and demo, with plans on its plans page. Strengths: fast variant creation for teams without front-end developers. Limits: no public price list.

5. Bloomreach: personalization alongside search and messaging

Bloomreach lists web personalization next to email, SMS, RCS, WhatsApp, mobile app, ads and retargeting, product recommendations and ecommerce search, all on its Loomi AI platform.

Pricing (as of October 2026): not published; Bloomreach sells through demos. Strengths: site personalization and search that share data with campaigns. Limits: most valuable if you use several Bloomreach products.

6. Insider One: personalization across site, app and messages

Insider One is a customer engagement platform that covers website personalization along with messaging channels and a customer data layer.

Pricing (as of October 2026): custom, scoped around the channels and data volume you activate, with identity resolution included. Strengths: one profile for the website and every message. Limits: proposals vary, so compare scope line by line.

7. Salesforce Personalization: for Salesforce-run enterprises

Salesforce sells Personalization as a Marketing Cloud add-on for web, mobile app and email personalization, and lists a higher Personalization+ edition for existing customers.

Pricing (as of October 2026): $8,000 per org a month, billed annually. Strengths: the only published price here, and native use of Salesforce data. Limits: a large commitment unless you already run Salesforce Marketing Cloud.

How to choose

If your team already runs A/B tests, start with Optimizely, Wingify or Kameleoon and add personalization to audiences where tests show a clear difference. If you run a large catalog, the recommendation engines in Dynamic Yield, Bloomreach and Insider One matter more than the test editor. Either way, keep onsite personalization in step with email and SMS; our roundups of ecommerce marketing automation platforms and loyalty program software cover those layers, and our customer data platform comparison covers the data that feeds them.

Frequently Asked Questions

What is website personalization software?
It is software that changes what a visitor sees on your site based on who they are and what they have done: different banners for new and returning visitors, product recommendations based on browsing, or offers for a specific segment. Most tools pair personalization with A/B testing so you can measure whether a personalized experience beats the default.

Which website personalization tools publish their prices?
Very few do. As of October 2026 Salesforce lists Personalization as a Marketing Cloud add-on at $8,000 per org a month, billed annually. Optimizely says every plan is individually packaged, and Dynamic Yield, Wingify (VWO and AB Tasty), Kameleoon, Bloomreach and Insider One sell through demos or quotes.

What is the difference between A/B testing and personalization?
A/B testing shows different versions to random groups to find one winner for everyone. Personalization shows different versions to different audiences on purpose. Platforms such as Optimizely, VWO and Kameleoon use test results to decide which experience each audience should get.

Is Google Optimize still available for personalization?
No. Google says Optimize and Optimize 360 have not been available since September 30, 2023, so it is no longer an option for testing or personalization.
