    ArchiveBox is a self-hosted app that lets you preserve content from websites in a variety of formats. Without active preservation effort, everything on the internet eventually disappears or degrades. You can build your own personal archive box

    Linkwarden is another good one

    For personal purpose, self-hosted solutions are better choices than on cloud.

    Use flask, Django, and SQL, or psql

    wget, but better?
    i think it does indexing as well. more than just wget.
