ArchiveBox takes a list of website URLs you want to archive, and creates a local, static, browsable HTML clone of the content from those websites. … It imports lists of URLs, renders the pages in a headless, authenticated, user-scriptable browser, and then archives the content in multiple redundant common formats (HTML, PDF, PNG, WARC) that will last long after the originals disappear off the internet.
