FAQ
Frequently asked questions about Spider.
What is Spider?
Spider is a leading web crawling tool designed for speed and cost-effectiveness, supporting various data formats including LLM-ready markdown.

How can I try Spider?

Does it respect robots.txt?
Yes, compliance with robots.txt is default, but you can disable this if necessary.
Unable to get dynamic content?
If you are having trouble getting dynamic pages, try setting the request parameter to "chrome" or "smart." You may also need to set `disable_intercept` to allow third-party or external scripts to run.
Why is my crawl going slow?
If you are experiencing a slow crawl, it is most likely due to the robots.txt file for the website. The robots.txt file may have a crawl delay set, and we respect the delay up to 60 seconds.
