About Keak
What Is Keak
Keak is an AI agent that tests your website and updates it to grow conversions. Instead of asking you to write every headline and button in a test by hand, it scans a page, generates alternative versions of the copy, calls to action and layout, launches the A/B tests, then promotes the winner on its own. No manual setup. The company's framing is direct: watch where visitors drop off, then let the agent test its way toward more of them converting.
That matters if you run a landing page or an ecommerce store and you know the page converts worse than it should, but you don't have a growth team to run experiments every week. Keak does the busywork of setting a test up. You point it at a page, it proposes changes, and the split traffic decides the outcome. Simple. You just review the results.
It gets added through a small JavaScript snippet in the head of your page, so it works with plain HTML/CSS/JS and most modern build setups, plus the big no-code builders. So what does it change? You can think of Keak as an AI-powered A/B testing tool and an AI conversion rate optimization tool rather than a standalone design app: it changes the live page rather than handing you a file to upload. The pixel is about 31KB gzipped, and Keak says variants apply in under 100ms with no visible flicker. It also reports that its statistics engine runs server-side using a sequential test method, which means it can call a winner before a fixed sample size is reached.
The limits are worth knowing up front. Automated variant generation is useful for copy and layout, but it won't redesign a site. If your problem is a confusing product, testing headlines won't fix it. Testing won't save a bad offer. Keak also works best on pages that already get steady traffic, because a test needs visitors to reach a result. Low traffic means slow answers.
Getting Started
- Sign up on the Keak site and add your website.
- Drop the Keak tracking snippet into the head section of your page.
- Point Keak at the page and the conversion goal you care about, such as sign-ups or checkouts.
- Let the agent scan the page and generate variant versions of headlines, calls to action and layout.
- Start the test, then watch live results in the dashboard or leave the winner promotion to the agent.

Key features
Automatic Variant Generation
Keak scans a page and builds alternative versions on its own, covering headlines, calls to action, layout and other conversion points. You don't write the variants. The agent proposes them and the test decides which one wins. For teams that never got around to A/B testing because setup was too slow, this removes the main excuse.
Hands-Free Test and Learn
Variants go live, traffic splits between them, and Keak promotes the winner without you stepping in. Set it once. That closes the gap between knowing you should test and actually running tests every week, which is where most small teams fall down. Then it keeps running.
Lightweight Tracking Pixel
The Keak script weighs about 31KB gzipped, loads without blocking page rendering, and Keak says it has minimal impact on Core Web Vitals. An anti-flicker layer prevents content flash so your layout stability score is protected. No flicker, no shift. The company reports variants apply in under 100ms with zero layout shift, which keeps the test invisible to visitors.
Sequential Statistics Engine
The platform runs its statistics server-side using a sequential method and can declare a winner sooner than a fixed sample size allows. That's the point. For a page with steady traffic, it means faster decisions and less time spent running a test whose direction is already clear. Keak presents this as the engine behind its automatic winner selection.
Broad Platform and Framework Support
Keak integrates anywhere you can add a JavaScript snippet to the page head. That covers plain HTML/CSS/JS and frameworks like Next.js, React, Vue.js, Angular, Svelte, Astro, Remix, Vite and Gatsby, plus builders including Shopify, WordPress, Webflow, Squarespace, Wix and Framer. Few tools in this space reach both custom front-ends and no-code sites this widely.
Multi-Language and Locale Targeting
The tracking pixel supports websites in more than 100 languages, and you can target visitors by browser locale to run market-specific tests. Good for global shops. For teams running the same store across several regions, that turns one page into several test surfaces without separate builds.
Live Results and Alerts
Results show up in a real-time dashboard, and Keak sends Slack and email notifications for key events. Simple. You can let the agent run and still keep an eye on what's changing, which fits teams that want automation without losing visibility. No blind spots.
Pros and cons
Pros
- Generates variants and runs tests automatically, so A/B testing no longer needs a dedicated engineer for every experiment.
- Works with both coded frameworks and major no-code builders, which broadens who can use it.
- The small, asynchronous pixel has minimal effect on page speed and Core Web Vitals.
- Sequential testing can call a winner sooner than a fixed-sample approach.
- Locale targeting and 100+ language support suit multi-market sites.
Cons
- Automated variants cover copy and layout, not full redesigns, so it won't fix a confusing product.
- Tests need enough traffic to reach a result, which limits value on low-traffic pages.
- Because changes go live on your real site, a bad variant can affect live visitors before it's replaced.
- Public pricing isn't clearly listed on the site, so budget planning may mean contacting the vendor.
