What do the bots actually get?

This page reads robots.txt, which states what launchpad.net asks of crawlers. A firewall or CDN can still refuse a bot that robots.txt allows. The live check requests the page as each bot and shows the status it gets.

Questions

Does launchpad.net block GPTBot?

Yes. launchpad.net’s robots.txt disallows GPTBot from the whole site (line 56: Disallow: /). GPTBot is OpenAI’s crawler for training data; blocking it doesn’t affect ChatGPT search, which uses OAI-SearchBot. Checked 9 November 2026.

Does launchpad.net block ClaudeBot?

Yes. launchpad.net’s robots.txt disallows ClaudeBot from the whole site (line 56: Disallow: /). ClaudeBot is Anthropic’s crawler for training data. Checked 9 November 2026.

Does launchpad.net block Google-Extended?

Yes. launchpad.net’s robots.txt disallows Google-Extended from the whole site (line 56: Disallow: /). Google-Extended is the token that controls whether Google may use pages for Gemini training and grounding; it doesn’t affect Google Search. Checked 9 November 2026.

Does launchpad.net block PerplexityBot?

Yes. launchpad.net’s robots.txt disallows PerplexityBot from the whole site (line 56: Disallow: /). PerplexityBot is the crawler that indexes pages for Perplexity’s answers. Checked 9 November 2026.

Can ChatGPT search find launchpad.net?

Not through its own crawler. launchpad.net’s robots.txt disallows OAI-SearchBot from the whole site (line 56: Disallow: /). OAI-SearchBot is the crawler behind ChatGPT search; blocking it keeps the site out of ChatGPT’s search answers. Checked 9 November 2026.
