| # llms.txt Directory Snapshot — May 2026 |
|
|
| > A snapshot of 735+ websites implementing the [`llms.txt` specification](https://llmstxt.org/) as of late May 2026. Compiled and maintained by [ThatDevPro](https://www.thatdevpro.com) as part of the [Awesome-llms-txt](https://github.com/SecretiveShell/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](https://thatdeveloperguy.com) contributes 10 entries to this directory: |
