Not everyone sees the web the same way.

These are not edge cases. These are your customers, your readers, your users.

Bright sunlight

A 45-year-old reading on a phone in bright sunlight needs higher contrast.

Long articles

A student with dyslexia working through a long article benefits from reading aids.

Low vision

A visitor with low vision needs higher contrast and larger text to read comfortably.

Motion sensitivity

Someone sensitive to animations needs a way to stop moving content.

A comfort layer for every visitor.

FlexViu is a small icon in the corner of your site. When a visitor opens it, they get personal control over their viewing experience. Preferences are saved locally and persist across visits. No account needed. No data leaves their device.

Everything your visitors need.

One script tag. That's it.

Three steps to a more comfortable website.

1

Add one line of code

Paste a single script tag into your site. Works with any CMS, framework, or static site.

2

Visitors see a small icon

A subtle icon appears in the corner. It doesn't alter your design or slow your site down.

3

They adjust, it persists

Visitors choose their preferences. Next visit, the site already feels like theirs.

<script src="https://cdn.flexviu.com/flexviu.min.js"></script>
<script>flexviu.init({ position: 'bottom-right' });</script>

Honest about what it does.

FlexViu is not a compliance tool. No overlay can make a site fully accessible — real accessibility requires accessible code and thoughtful design. FlexViu complements that work.

Aspect Overlay Tools FlexViu
Promise "AI-powered compliance" "A better experience for every visitor"
Size 100–500 KB ~6 KB gzipped
Privacy Tracks usage, cloud-dependent Zero tracking, localStorage only
Backend Cloud servers None — fully client-side
Price $490–$3,990/year Free / from CHF 290/year
Compliance claims Bold (and challenged in court) None — honest positioning

Built for developers who care about craft.

Minimal footprint. Maximum respect for your existing code.

Shadow DOM

Full encapsulation. No style conflicts with your site. The widget lives in its own isolated DOM.

Zero dependencies

No runtime dependencies. No jQuery. No React. Just a single IIFE bundle that works everywhere.

Framework-agnostic

Works with WordPress, Next.js, Astro, Hugo, Shopify, static HTML — anything that runs in a browser.

TypeScript source

Written in TypeScript. Available via script tag, WordPress plugin, or npm package.
