AI generates variations of your website, tests them automatically, then updates your site with whatever works better. That's the pitch. Keak analyzes your pages, headlines, CTAs, layouts — creates alternatives, splits your traffic, and reports back through a real-time dashboard. You get Slack and email alerts when tests hit significance.

The technical execution matters here. Variants load in under 100ms with zero layout shift. The script weighs about 31kb gzipped and loads asynchronously, so it won't tank your Core Web Vitals. There's an anti-flicker overlay to prevent that annoying content flash during variant loading. The statistics engine runs server-side using SPRT, not client-side guesswork.

Integration coverage is solid. Works with Next.js, React, Vue.js, Angular, Svelte, Astro, Remix, Vite, and Gatsby on the developer side. Also plugs into Shopify, WordPress, Webflow, Squarespace, Wix, and Framer. Plain HTML/CSS/JS sites work too. Browser locale targeting lets you test market-specific variations across 100+ languages.

Four different products split the service. Keak Code targets developers who want full control. Keak Extension is the no-code version that supposedly installs in 2 minutes. Keak Acquire offers fixed-price conversions at scale — whatever that means in practice. Keak Agents handles A/B testing for AI agents, which is niche but increasingly relevant.

What's missing from the facts: any user count, conversion improvement percentages, or case studies. No information about test duration requirements or minimum traffic thresholds. The "automatically updates sites" claim needs scrutiny — does it auto-deploy winning variants or just recommend them? That distinction matters for risk management.

The browser extension exists. That's confirmed.

The 100ms application speed and zero layout shift are specific claims worth testing. If variants cause any visual jumping or delay, that undermines the whole value proposition. The 31kb script size is reasonable but not tiny — compare it against your existing page weight.

Browser locale targeting for 100+ languages sounds useful for international sites, but there's no detail on how it handles right-to-left languages or complex scripts. The statistics engine being server-side should mean more reliable results than client-side tracking, but you'd want to verify how it handles bot traffic and ad blockers.

No limitations listed in the facts. Real tools have constraints. Traffic minimums? Test duration limits? Variant quantity caps? Those details aren't here.
