What's the best way to A/B test a Webflow site in 2026?
Updated July 2026
Side-by-side: Webflow Optimize vs Humblytics A/B testing
When each wins: Webflow Optimize wins if you want AI traffic allocation and 1:1 personalization built into the Webflow Designer. Humblytics wins when you need affordable element-level tests, heatmaps per variant, and proof that a variant moved revenue, on any plan, cookie-free.
Every plan gets every tool.
Analytics, heatmaps, funnels, the A/B editor, revenue attribution and the MCP, all on the first plan. You pay for traffic, not features.
For teams letting Claude or Codex operate the loop.
Everything you need to run the loop:
- 500K events/mo
- Unlimited websites
- 5 A/B tests · 5 funnels · 5 heatmaps
- Meta ad attribution (Google Ads soon)
- Hosted MCP + REST API
- 200 AI chat credits/mo
- Cookie-free, no consent banner
The in-house growth lead
Runs $2,500 to $25,000 a month in ads on one or two sites, somewhere between 10,000 and 500,000 visitors. Makes $5,000 or more a month through Stripe and wants to know which pages earn their keep.

What counts as an event?
Pageviews, clicks, and form submits, auto-tracked from one script. Heatmap interactions are bundled into pageviews.
What if I exceed my limit?
We email you at 75% usage. Past the limit you get a 3-day grace period, then tracking pauses until you upgrade, add an events add-on ($39/mo per 1M), or your limit resets on the 1st of the month.
Can I cancel anytime?
Yes. Month-to-month, cancel in two clicks. Your card won't be charged until the 14-day trial ends.
