Researched and fact-checked by Bartu Cavusoglu · Updated October 26, 2026
Optux AI is a website experimentation platform that combines A/B testing, split testing, SEO experiments and personalization in one tool. It is aimed at marketers, product managers and agencies who want to learn what works on a live site using real user data instead of opinion.
The product describes itself as a complete experimentation toolkit. Its homepage gives examples such as testing testimonial placement, comparing a short sign-up process with a longer one, testing H1s and meta descriptions, and showing different homepage messages to new and returning visitors.
Optux AI runs on Cloudflare. It uses Cloudflare Workers to modify pages while they pass through Cloudflare's servers, so visitors receive the changed version and the original website is not touched. Teams can use their own Cloudflare account, or Optux AI's account if they have none, provided they can manage the domain through their registrar.
Changes are made in a visual editor, where a reviewer on the site describes clicking and editing an element much like an image, or in a code editor. The documentation covers automatic installation, turning on the Cloudflare proxy and manual Worker installation. One reviewer says DevOps installed it in under 15 minutes without backend changes.
On the testing side, plans include unlimited variations, unlimited goals and metrics, multi-page campaigns, traffic allocation from 5% to 100% and multi-armed bandit auto-allocation. SEO patching lets teams change elements such as headings and meta descriptions without a full release, and winning changes can be deployed or exported as HTML and CSS.
Personalization covers targeting by UTM parameter, country, browser, device, operating system, GA4 audience and new versus returning visitors. AI text personalization adapts copy by location, language, browser or device and supports custom prompts. The plan table also lists Figma import, UX Genie, single sign-on, role-based permissions and EU-based servers.
Optux AI is a website experimentation tool for A/B testing, split testing, SEO experiments and personalization. It uses Cloudflare Workers to change how a site is served to visitors, so teams can test changes without altering the original website.
Optux AI has a Free plan at $0, Pro at $39/month, Business at $299/month and custom Enterprise pricing. Yearly billing saves 20%, with annual totals shown as $468 for Pro and $3,828 for Business.
Yes. The Free plan costs $0 per month, includes 1 seat, 5K MTU for A/B testing and 500 MTU for AI text personalization, and allows only 1 patch. The sources do not mention a time-limited free trial.
Optux AI runs on Cloudflare Workers, but you can use Optux AI's own Cloudflare account if you do not have one. You still need access to domain management through your domain registrar.
Yes to both, according to the FAQ. It works on top of the site as served, so you point your Webflow domain through Cloudflare. It also fully supports single page applications, including React, Vue and Svelte.
The FAQ says Optux AI has no effect on the original website because it only modifies how pages are served to visitors. You can turn it off at any time.
The FAQ confirms Google Analytics 4 for tracking experiments and says other tools are coming soon. The pricing page also lists Segment, Mixpanel, Matomo, Heap, Hotjar and custom integrations, so confirm availability before buying.
You can export the changes made in Optux AI as HTML and CSS and merge them into your website's code. The pricing page also lists a deploy winning test changes feature.
