Other great apps like TechRewind are ArchiveBox (Free, Open Source), Archive.is (Free), Archive.st (Free) and Resurrect Pages (Free, Open Source).
Because modern websites are complicated and often rely on dynamic content, ArchiveBox archives the sites in several different formats beyond what public archiving services like Archive.org and Archive.is are capable of saving.
Dead pages, broken links, the scourge of the internet. Powerhouse sites like Slashdot and Digg can bring a server to its knees. What do we do when a page is dead but we still want to see it? Call in the clerics, and perform a resurrection ceremony!
