SiteSucker Pro for macOS

If you have ever used a tool like wget or curl to mirror a directory of PDFs, SiteSucker Pro is the graphical counterpart that does not hide the mechanics. The interesting parts are not the download button, but the rule sets around it. The Limits section is where you constrain a crawl before it balloons: maximum link depth, total file count, and a floor and ceiling for file size. A misconfigured depth value is the difference between grabbing a single tutorial and mirroring an entire university domain.

The Paths section is where experienced users will spend most of their time. It lets you force the app to fetch specific URLs that a normal crawler would miss, or skip directories that are just noise. Combined with the content-type filters, you can pull down only the stylesheets and images from a reference site without filling a drive with HTML you will never read.

SiteSucker respects robots.txt by default, but that exclusion is a toggle in settings. For local mirrors of your own sites, turning it off is often the correct move. The app also writes an operation log from the moment a download starts, and you can open that log file directly in Console to trace a failed request or a redirect loop.

Version 6.2.2 is a maintenance release for macOS 14.0 and later. It fixes bugs in the PDF creation pipeline and adds a Format HTML option to the Webpage settings, which is useful if you want the saved markup to be readable instead of a single compressed line.

A teacher grabbing a site before a classroom without Wi‑Fi

A secondary-school biology teacher needs a copy of an interactive HTML anatomy atlas for a lesson in a lab where the Wi‑Fi is unreliable. She gives SiteSucker the atlas URL, sets Levels to 3 under Limits so she gets the main diagrams plus the linked detail pages but not the whole textbook repository, and unchecks everything except HTML and images in File Types. Twelve minutes later the site sits in a local folder. The directory structure mirrors the original, so relative links between pages and image folders work exactly as they do online. She copies the folder to a USB stick, walks into the lab, and opens the index page in Safari with no network icon in sight. The embedded anatomical animations that were PNG sequences play fine; a YouTube video on cell division does not, because she used SiteSucker rather than SiteSucker Pro and left the embedded‑video option off. That is a quick re‑download later.

Why SiteSucker’s download policy makes it invisible to most servers

Will it pull down video from YouTube and Vimeo?

SiteSucker Pro will download embedded YouTube and Vimeo videos when the page references them as standard
