web-archive
Ghostarchive
A small independent on-demand archiver, notable for handling YouTube videos and Twitter posts as well as ordinary web pages. Snapshots are reached by direct links to individual archive pages; there is no search API. Check it when hunting for preserved copies of social-media content that mainstream web archives tend to capture poorly.
