Site Sucker
Downloads websites as browsable offline copies, rendering JavaScript pages through Chromium.

About
A website downloader for macOS, Windows and Linux, drawn with MyGo's native UI on the GPU, with no web view. It saves pages with their CSS, scripts, images, fonts and media and rewrites links so the copy browses offline, renders JavaScript-heavy pages in a local Chrome or Chromium, and can crawl through HTTP, HTTPS or SOCKS5 proxies with authentication. It respects robots.txt by default.
