Vercel: what its llms.txt contains
Measured on 2026-08-31: 3.4 KB, 8 sections, 18 links. How that compares with the other 118 files we track, and what it implies.
Last updated:
The file
Vercel publishes an llms.txt at
https://vercel.com/llms.txt.
The file declares itself as Vercel in its H1, and the host is categorised here as developer tools. It was last fetched and parsed on 2026-08-31.
Measured structure
| Measure | Vercel | Corpus median | Percentile |
|---|---|---|---|
| Size | 3.4 KB | 14.0 KB | 13th |
| H2 sections | 8 | 8 | 55th |
| Links | 18 | 76 | 20th |
| Blockquote summary | Present | 99 of 119 have one | n/a |
Percentiles are against the 119 files in this directory, not against the web. That population is deliberately weighted toward documentation platforms and developer tools, which is where the convention started, so treat it as a peer group rather than a norm.
Observations
- 18 links is a tightly curated file, well under the corpus median of 76. That is the shape the proposal describes.
Comparable files
Closest in size within developer tools, from the same weekly check:
- Vite: 3.4 KB, 1 sections, 43 links
- Postman: 3.3 KB, 5 sections, 18 links
- DuckDB: 3.3 KB, 4 sections, 12 links
- Sentry: 3.6 KB, 10 sections, 57 links
How this was measured
Our checker fetches /llms.txt for every host in the directory, follows redirects, confirms
the response is Markdown rather than an HTML error page, and parses it with the same parser that powers
our validator. Sizes are of the served body, sections are H2 headings,
and links are Markdown links anywhere in the file. The run behind this page completed on 2026-08-31.
