Personalization tools: enable personalization with the right tool

Tools that can actually change what someone sees, compared by stack role and business model: where each is strong, where it runs out, and what to ask before you buy more of it. Inclusion is not an endorsement.

All personalization tools

Adobe Target

Uses machine learning (a Random Forest model plus a multi-armed bandit) to automatically select the best-performing, marketer-defined experience for each visitor, rebuilding its model roughly every 24 hours.

Optimizely Personalization

Delivers real-time, audience-targeted experiences inside the same platform as Optimizely's A/B testing and feature-flagging tools, with audiences built from behavioral, CRM, and Optimizely Data Platform signals.

Webflow Optimize

Runs three experience types on Webflow sites: standard A/B tests, AI-optimized tests that keep shifting traffic to whatever's currently working instead of calling one winner, and manual rules-based personalization for defined audiences.

AB Tasty content personalization

Audience- and intent-based content targeting for anonymous visitors, built on live signals (referral source, device, location, scroll depth) rather than login or cookie data. As of September 2026, AB Tasty and VWO merged their brands under the new parent brand Wingify, with each platform still running independently during the transition.

Kameleoon Audiences

Experimentation platform with an AI Predictive Targeting feature that scores each visitor's likelihood to convert (0-100) and lets you target or exclude by that score.

Dynamic Yield

Personalization and recommendations platform with a merchandising engine and Experience APIs for running recs and server-side experiments on any channel.

VWO Testing
