Import URL lists
Import single or multiple URLs from plain text files, CSV files, XML sitemap files, the Clipboard or enter URL addresses manually. Import links from multiple files.
Request headers / User agents
Set custom HTTP request headers. Set the User Agent from a list of 20 pre-built agents (search engine bots, mobile devices and browsers). Completely customize the User Agents at any time.
Rewrite URLs on the fly (for example to the staging environment of a website migration).
Set a proxy for all URL status checks. Use password protected proxies.
Use HEAD or GET requests
The software can use HEAD or GET requests. HEAD requests are faster and save time on huge URL lists but not all servers allow them. Use HEAD requests when checking large lists of URLs from a domain/website that supports them. Use GET requests when checking large lists of domains.
