How do I host llms.txt on a subdomain?

Solo+ feature - we serve your llms.txt at <slug>.llms.llmsubmitter.com.

Intermediate Last updated 2 May 2026

If your hosting doesn't let you upload arbitrary files to the root (some PaaS, Webflow, Squarespace), you can't host llms.txt directly. Solo+ tiers let us host it on your behalf:

  1. Open /app/sites/{id}/llms-txt-host.
  2. Enable hosting and pick a slug (defaults to your sanitised domain).
  3. We serve your llms.txt at https://{slug}.llms.llmsubmitter.com/llms.txt.
  4. Add a CNAME on your domain pointing llms.your-site.com to that subdomain (or just link to the LLM Submitter URL from your homepage).

The content is editable from the same page; every save bumps a version number and AI crawlers re-fetch on their next pass.
