llms.txt Directory Snapshot — May 2026

A snapshot of 735+ websites implementing the llms.txt specification as of late May 2026. Compiled and maintained by ThatDevPro as part of the Awesome-llms-txt community list.

What is llms.txt?

llms.txt is a proposed standard for websites to declare LLM-readable summaries at a stable URL. Crawlers (GPTBot, ClaudeBot, PerplexityBot) check /llms.txt and /llms-full.txt to retrieve a curated overview of the site without parsing the full HTML.

Coverage

This snapshot contains 735 unique websites with verified llms.txt files, plus an additional ~30 with llms-full.txt variants. Joseph Anady's ThatDeveloperGuy network contributes 10 entries to this directory:

Use cases

Train/evaluate AI crawlers to discover llms.txt deployments
Benchmark llms.txt adoption rates across industries
Seed corpus for MCP-llms-txt and similar LLM context tools
Research the geographic and industry distribution of llms.txt early adopters

Methodology

URLs sourced from the community-maintained SecretiveShell/Awesome-llms-txt GitHub repository, fork at Janady13/Awesome-llms-txt, enriched with ThatDevPro network entries.
