Zero Lighthouse tax
Social proof that doesn't slow your site down.
Founders have literally ripped their wall of love off the homepage because the embed tanked Core Web Vitals. trustproovr is a tiny async script in a Shadow DOM — proof without the performance bill.

The short version
Third-party embeds are heavy — that's the wall most founders hit. trustproovr's answer: it asks your users when they're engaged, drafts the testimonial from how they actually use the product, and renders the ones you approve looking native to your site.
- Shadow DOM, tiny payload
- Async, deferred, zero CLS
- Asks when the session's earned it
The problem
1. Third-party embeds are heavy
Iframe walls ship a whole app: fonts, frameworks, trackers. Your Lighthouse score pays for all of it.
- One script tag — no plugins
- Draft written from real usage
2. Layout shift on every load
The wall pops in late, pushes content down, and CLS dings you. Google notices; so do visitors.
- Asks only when the session's engaged
- You approve before it ships
3. The fix people actually choose
Remove the testimonials entirely. Score goes green, page goes untrusted. Lose-lose.
- Draft written from real usage
- Renders in your fonts + colors
What trustproovr does about it
Turns the users you have into proof.
1. Shadow DOM, tiny payload
The widget renders in an isolated shadow root with zero framework overhead — it can't leak CSS or block your main thread.
- One script tag — no plugins
- Draft written from real usage
2. Async, deferred, zero CLS
The script loads async and the wall mounts where you put the div — no layout shift, no jank.
- Asks only when the session's engaged
- You approve before it ships

Will the embed hurt my Core Web Vitals?
No — the script loads async, renders in a Shadow DOM, and mounts exactly where you place it. No framework payload, no layout shift.
How does it avoid CLS?
The wall mounts inside the div you position — content never jumps because the container is already there.
Does it work with my stack?
Anywhere a script tag runs — plain HTML, React, Next.js, Webflow, WordPress, Framer. No npm package required.
