alchemy.com website review

About 517 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.2 s faster on a phone.

Your mobile performance score is 56. Pages that score under 90 lose visitors before the first paint.

11 files are served with short cache lifetimes, so returning visitors download them again (161 KiB).

8 third-party services load with your homepage (Google Tag Manager, Heap and ContentSquare and others), adding 1,005 KiB and 706 ms of main-thread time.

Google Tag Manager costs a phone 472 ms of main-thread work and 513 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Polyfills for old browsers add 58 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 3.2 s on main-thread work while loading, 1.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

11 long tasks block the main thread while loading, the longest for 283 ms. During a long task the page ignores taps.

The page has 1,502 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 15.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Alchemy app dashboard showing request metrics and health ch…”.

The page becomes fully interactive after 15.5 s. Good is under 3.8 s.

Visually, the page fills in at 6.1 s (Speed Index). Good is under 3.4 s.

Real visitors wait 225 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

Real visitors wait 939 ms for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 461 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 247 ms to 256 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.0 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.1 MB in 125 requests on a phone: scripts 1.5 MB (50), fonts 207 KiB (3) and images 162 KiB (31). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.59 g of CO₂e: 71.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

5 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

3 tap targets are too small or too close together to hit reliably with a finger.

6 visible links have no text or label, so screen readers cannot say where they go.

Elements with visible text labels do not have matching accessible names. (27 elements).

The homepage links to 140 pages on alchemy.com and 47 external pages.

We fetched 15 pages linked from your homepage (of 71 found) and read each the way a search engine does.

5 of 10 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

HSTS is set, but max-age is 182 days; one year is the recommended minimum.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

alchemy.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 1,396 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Heap and X (Twitter) Ads (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 11 cookies (measured from a US location before any click).

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.

Loading the homepage contacts 19 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
