your visitors do.
Steterly reads your whole site the way an editor reads a galley proof and flags the typos, broken links, dead images, oversized media (images 3MB+, videos 25MB+), missing image alt tags, duplicate/missing H1s, stale copyrights, placeholder text, missing meta tags and slow page speeds your team stopped seeing months ago.

Shop the collection LCP 3.4s — slowWhat Steterly catches
Typos & grammar
An AI proofreader runs over every paragraph. It knows the difference between their and there, won't flag your brand name as a mistake, and works in nine languages including the one you're reading.
Broken links
Every anchor on every page. We follow redirect chains to the end, retry on rate-limits, and tell you which page the broken link lives on.
linked from /about, /press
Dead images & large media
If your hero image is 404'ing on a CDN, Steterly sees it before your visitors do. We also check media asset sizes to flag oversized images (3MB+) and videos (25MB+) that slow down your pages.
→ Flagged as large image
Outdated copyrights
A © 2019 in the footer is a tell. We check it on every page, not just the homepage.
→ should be 2026
Placeholder text
Lorem ipsum. (555) 555-5555. your@email.com. TODO. coming soon. Every variant of unfinished.
Meta titles & descriptions
Every page needs a title and description. We flag pages where these essential SEO tags are missing or left empty.
→ Add to <head>
PageSpeed
Every scan includes a full Core Web Vitals breakdown, ensuring your site is not only error-free but also blazingly fast.
→ target < 2.5s
Accessibility Checks
Automated WCAG 2.1 Level AA scanner. We analyze the HTML to catch critical barriers like missing image descriptions, unlabelled forms, broken ARIA roles, and empty buttons. See checks and limitations →
→ No accessible name (WCAG 4.1.2)
Beyond the basics.
Teams
Invite your whole team to review scan reports. Assign different roles and keep everyone on the same page when resolving site issues.
Ignore Rules
Tired of the same false positive? Set up robust ignore rules based on URL patterns, paths, or specific HTML elements so we never bother you about them again.
Custom Dictionary
Train the proofreader. Add industry-specific jargon, your brand's unique product names, and technical terms to your site's custom dictionary.
Full or Partial Scans
Run a comprehensive scan, or select specific modules like AI proofreading, SEO checks, or broken links to run targeted scans in a fraction of the time.
Platform compatibility
Works where your site lives.
Steterly reads the rendered frontend like a visitor, so it's platform-agnostic by design. Nothing to install, nothing to slow your pages down.
