Speed
vercel.app adds 1.0 s
1.0 svercel.app costs a phone 1.0 s of main-thread work and 603 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.
Mobile performance score: 38
38/100Your mobile performance score is 38. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.
Main-thread work: 4.9 s
A phone's processor spends 4.9 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.
3 third-party services on the page
3 third-party services load with your homepage (vercel.app, JSDelivr CDN and Google Fonts), adding 696 KiB and 1.3 s of main-thread time.
Render-blocking requests
600 ms1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 600 ms.
12 long tasks on the main thread
12 long tasks block the main thread while loading, the longest for 585 ms. During a long task the page ignores taps.
Reduce unused JavaScript
345 KiBAbout 345 KiB of JavaScript is downloaded but never used on this page.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.
Minify CSS
5 KiB5 KiB could be saved by minifying CSS.
Minify JavaScript
3 KiB3 KiB could be saved by minifying JavaScript.

Core Web Vitals
First Contentful Paint: 6.4 s
6.4 sThe first text or image appears after 6.4 s on a phone. Good is under 1.8 s.
Largest Contentful Paint: 6.4 s
6.4 sYour largest element takes 6.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “the source.”.
Total Blocking Time: 1.2 s
1.2 sScripts block taps and scrolling for 1.2 s in total while the page loads. Good is under 200 ms.
Time to Interactive: 11.0 s
11.0 sThe page becomes fully interactive after 11.0 s. Good is under 3.8 s.
Speed Index: 6.4 s
6.4 sVisually, the page fills in at 6.4 s (Speed Index). Good is under 3.4 s.
1 image without width and height
1 image have no width and height attributes, so the layout jumps as each one loads.
Not enough real-visitor data yet
Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Cumulative Layout Shift: 0.002
0.002The layout barely moves while loading (CLS 0.002, good is under 0.1).
Images and page weight
About 0.5 g of CO₂ per visit
0.46 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.46 g of CO₂e: 54.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
1 checks passed
Page weight: 1.6 MB in 25 requests
1.6 MBYour homepage downloads 1.6 MB in 25 requests on a phone: HTML 938 KiB (2), scripts 589 KiB (14) and fonts 96 KiB (5). That is a lean page.
Accessibility
Elements must only use permitted ARIA attributes (1 element)
Elements must only use permitted ARIA attributes: 1 element on the page fails this check, rated serious by axe-core.
Scrollable region must have keyboard access (1 element)
Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.
Heading levels should only increase by one (1 element)
Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

Every image has alt text
All 11 images in the HTML carry an alt attribute.
43 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 46 WCAG 2.2 A/AA and best-practice rules on the phone render: 43 passed and 3 failed. 3 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
No XML sitemap
No XML sitemap at https://www.nxos.com/sitemap.xml, so Google discovers your pages only by following links.
No robots.txt
There is no robots.txt at nxos.com/robots.txt, the first file search crawlers ask for.
Only 0 internal links
The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.
5 checks passed
Meta description: 144 characters
Your meta description is 144 characters: “Nexus Origin Systems is a venture studio building super-intelligent products from ground truth across culture, technolo…”.
One H1 headline
Your main headline reads: “Built fromthe source.”.
Title: 50 characters
Your title is a healthy 50 characters: “NXOS — Nexus Origin Systems: Built from the Source”.
Canonical URL set
The canonical URL is https://nxos.com/.
Open Graph tags complete
Open Graph tags are complete, so shared links show a title, description and image.
AI search readiness
No Organization structured data
There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.
No llms.txt
There is no https://www.nxos.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.
2 checks passed
AI answer engines may read the site
There is no robots.txt, so nothing stops the crawlers behind ChatGPT search, Claude and Perplexity from reading the site and cite it in answers.
Text is in the HTML
Your server sends the page's text in the HTML (680 words), so crawlers that don't run JavaScript still read it.
Best practices
1 small tap target
1 of 5 tappable elements near the top of the page is smaller than 24 px, hard to hit with a thumb.
2 checks passed
No console errors
No JavaScript errors were logged while the page loaded on a phone.
Mobile viewport set
The page declares a mobile viewport.
Content and conversion
No call to action on the first screen
On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.
No calls to action
We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.
No analytics detected
No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.
Only about 187 words
The homepage has only about 187 words of visible text; thin pages give Google and first-time buyers little to go on.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
3 checks passed
1 short form
A short form (1 field at most) is right on the homepage.
Social proof on the page
Social proof on the homepage: 2 testimonial or review blocks and 11 trust badges.
Direct contact links
Visitors can reach you directly: 0 phone links and 1 email link.
Privacy and tracking
No consent tool detected
No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.
3 other companies contacted
Loading the homepage contacts 3 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
1 checks passed
No known trackers before consent
No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
Security, domain, email and software versions
The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at nxos.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
