Adding llms.txt to a Bubble app
Published:
Bubble renders your app as HTML and doesn't serve arbitrary plain-text files at the root — so an llms.txt needs a small layer in front. Two reliable options.
Option 1 — an edge proxy (most robust)
If your Bubble app is behind Cloudflare (or another CDN) on your custom domain, serve /llms.txt directly from a small edge worker that returns your text with Content-Type: text/plain. This keeps the canonical root URL and never touches Bubble.
Option 2 — host the file + redirect
Host the raw text where it serves as plain text (object storage or a CDN), then redirect /llms.txt to it at your DNS/CDN layer. A crawler follows the redirect to your file.
Why not a Bubble page?
A Bubble page named "llms.txt" still renders as the HTML app, not plain text, so it won't validate. The file must be served as text/plain — hence the proxy or hosted-file approach.
Validate
Paste your domain into the validator to confirm /llms.txt is reachable as plain text and every link resolves.
