Firecrawl llms.txt generator against Yoast and other WordPress llms.txt plugins on what an agent reads
In short
Firecrawl offered an alpha /llmstxt endpoint that turns any website into llms.txt and llms-full.txt files. Yoast cannot generate the file while another llms.txt already exists on the server. Firecrawl llms.txt generator leads on llms.txt generation, 2 to 1; Yoast and other WordPress llms.txt plugins: /llms.txt returned 404 after activation because the wpseo option enable_llms_txt was false.
The sourced difference
Firecrawl builds llms.txt once from a crawl of any site and its hosted endpoint is unmaintained since 2025-06-30; Yoast regenerates the file weekly on WordPress but lists only the 5 most recently updated items per type by default. Source, read 4 November 2026.
