Screaming Frog is a powerful website audit tool that can crawl in your website's pages and return with detailed results. You will receive detailed reports of your ALL internal and external links. The reports then can be used to make proper adjustment to your website's SEO, such as finding broken links or auditing duplicate title tags.
You do not have to manual check every page on your website now and can save much time and money instead of asking your webmaster to do so :)
Note: I am able to supply with about 100k report URLs per domain.
