The Chrome extension that turns Webflow Optimize into a real A/B testing analytics platform.
See every metric Webflow hides. Real-time dashboards, multi-goal tracking, audience segmentation, statistical analysis, and AI-powered insights — all in one side panel.
You launch an A/B test and get a results page with blurred data tables, one goal at a time, no segmentation, and no statistical rigor. You're left guessing if your test actually won.
See sessions, conversion rates, lift, and confidence for every variation — instantly. Color-coded verdicts (Strong Winner, Loser, Inconclusive) so you know exactly what's happening.
Webflow shows one goal at a time. CRO Sidekick scrapes and displays all 8+ goals simultaneously with a lift comparison bar chart. See Add to Cart, Checkout, Purchase, CTA Clicks, and more — in a single view.
Break down results by Traffic Source, Device Type, New vs Returning, Country, Browser, and OS. Discover that your winner on desktop is a loser on mobile — before you roll it out.
Generate interim or final test reports with one click. AI summarizes your results with clear verdicts and recommendations. Copy as JSON for your data pipeline. Configure confidence levels, hypothesis type, and use the built-in sample size calculator.
CRO Sidekick extracts and computes metrics that Webflow Optimize doesn't surface.
Add CRO Sidekick from the Chrome Web Store. No account or login needed.
Navigate to an experience in Webflow Optimize. The side panel activates automatically.
Dashboard, goals, segments, reports, and AI insights — all extracted in milliseconds.
CRO Sidekick runs entirely in your browser. No data is sent to any server. No analytics, no tracking, no accounts. It reads the Webflow Optimize page you're already on and does the math locally.
Install CRO Sidekick and see what Webflow Optimize really has to say about your tests.
Free on the Chrome Web Store
CRO Sidekick for Webflow Optimize — Last updated: February 23, 2026
CRO Sidekick is a browser extension that analyzes A/B test data from Webflow Optimize. This policy explains how the extension handles data.
CRO Sidekick does not collect, transmit, or store any personal data. The extension reads experiment data (variation names, session counts, conversion rates) from Webflow Optimize pages you visit. This data is processed entirely within your browser.
User preferences (confidence level, hypothesis type) and experiment notes are saved locally using Chrome's storage API. This data never leaves your device.
The only network requests made by the extension are to optimize.webflow.com, using your existing authenticated session, to fetch additional goal and dimension data for the experiment you are viewing.
No data is shared with, sold to, or transferred to any third party.
