Fast Link Checker has a flexible management system and can check links to documents, images, scripts and other files. You can check links either only on one page or restrict the level of subdirectories it checks.

It supports HTTP, HTTPS and SOCKS proxy servers. Fast Link Checker allows you to generate and save reports. Fast Link Checker allows you to generate and save reports.
