AhrefsSiteAudit is a web crawler that powers Ahrefs' Site Audit tool. Ahrefs users can use Site Audit to analyze websites and find both technical SEO and on-page SEO issues.
This bot can crawl any website unless disallowed, and prevents excessive load on website servers by limiting crawling to 1 request per 2 seconds by default. If you're a website owner, you can crawl your own sites at higher speeds and also allow AhrefsSiteAudit crawler to ignore robots.txt. To do that, you'll need to verify ownership in Site Audit tool.
