SEO Spider General
Installation
The Screaming Frog SEO Spider can be downloaded by clicking on the appropriate download button for your operating system and then running the installer.
The SEO Spider is available for Windows, Mac and Ubuntu Linux. The SEO Spider is not available for Windows XP.
The minimum specification is a 64-bit OS with at least 4gb of RAM available.
The SEO Spider is capable of crawling millions of URLs with the correct hardware, memory and storage. It is able to save crawl data in RAM, or to disk in a database.
For crawls under 200k URLs, then 8gb of RAM should generally be sufficient. However, to be able to crawl over 1 million URLs, an SSD and 16gb of RAM (or higher) is our recommended hardware.

If you’re new to the SEO Spider, please read our getting started guide.
