# IndieLLMs > A free llms.txt validator for sites and documentation. IndieLLMs is a free, one-input web utility for indie makers at indiellms.com. It takes one url, for example https://example.com/, and answers in about ten seconds. Every answer names its source next to it. No account, no card, no premium plan, no upgrade nag, no hidden paywall. Private lookup activity is never published, and nothing on the page counts anyone. Every page is static HTML, and each link below is that page as Markdown or plain text.
