About our scanner bot
If you found this page in your server logs, hello - here's exactly what visited you and why.
LightmorphicAccessBot is the scanner behind Lightmorphic Access, a free accessibility checker for small businesses. When someone enters a domain on that page, the bot fetches the site's homepage plus a small number of key pages (typically 10–20), reads the HTML and stylesheets, and produces an accessibility report.
What it does and doesn't do:
- It only visits a site when a person has actively asked for a scan of that exact domain.
- It fetches a bounded number of pages, once, with timeouts - it never crawls continuously or site-wide.
- Repeat scans of the same domain are served from a short-lived cache rather than re-fetching.
- It doesn't execute JavaScript, submit forms, or try to get past logins.
- It respects a robots.txt block: scans of sites that refuse bots report exactly that to the person scanning, and stop there.
How to block the bot
If you'd rather it never visited your site, add this to your robots.txt:
User-agent: LightmorphicAccessBot Disallow: /
Blocking it costs you nothing here: a scan of a site that blocks the bot simply reports that it could not look. The common questions cover what a scan looks at.
