Your landing page, rewritten for each visitor's intent.

Flawlee reads the signals every visitor already carries — UTM, referrer, device, behavior, geo — and rewrites your hero, subheadline, and CTA to match, at the edge, in milliseconds. One tag. No redeploys. No flicker. Paste your URL below to see it on your site.

01 / How it works

One tag. Three steps.

Flawlee sits between your CDN and the page. Reads who arrived, picks a variant from your library, and swaps words before render — never after.

STEP 01

Drop in one script.

Two lines before </head>. Works with any stack — Webflow, Next.js, WordPress, Shopify, plain HTML. No framework adapters.

<!-- once -->
<script async src="https://flawlee.com/flawlee.js"
        website-id="YOUR_ID"></script>
STEP 02

Mark the words that change.

Add data-flw="hero-headline" to any element. Or pick elements visually in the inspector. Words become slots; everything else is left alone.

SOURCEBook a cleaning
SLOT{{ hero-cta }}
STEP 03

AI matches each visitor.

UTM, referrer, geo, device, behavior — Flawlee reads the signals each visitor already carries and picks the variant that fits. Variants ship instantly: no redeploy, no approvals.

CONTROLBook a cleaning
VARIANTMove-out cleaning service
02 / Variant studio

One page. A reading for every visitor.

Generate variants from a single source string and run them as experiments. Each variant knows who it's for, how it performs, and where it shows — on one screen.

The page that learns from every visitor.

Flawlee routes more traffic to the variants that convert — per audience, in real time. No tests to stop, no winners to declare. The page just gets better as data accumulates.

04 / Install

Two lines and a pulse.

Install is the only place where dark surfaces appear. The code stands out because nothing else tries to. Visitor detection is automatic — drop it in once and forget.

Before </head>

The Flawlee tag is async, edge-cached, and weighs less than 8 KB. It runs before the hero paints — visitors never see a flicker.

  • No flicker. Edge swap before paint — no layout shifts, no FOUC.
  • Any stack. Webflow, Next.js, Astro, WordPress, Shopify, plain HTML.
  • Privacy-first. No third-party cookies. Just UTM and referrer — no PII.
  • GDPR & CCPA compliant. Data anonymized at rest. DPA on request.
