Which of all of these is the best? Which is most likely to still have my files after 5+ years?

[hardwaresofton]

The one I posted is (mine and) amateur, don't use it.

It will probably be around for 5 years, but is not undergoing active development, and it was a side project I worked on for funsies (I may come back to it one day, and it's kind of a leave-it-be project, especially without 100s of users).

Please refer to the other ones for a serious (or at least more well thought out) solution.

Purrrl files never expire.

I'm getting a 301 when I try to upload to chuck.io.

I use curl.io from time to time and it has a big drawback: you need to visit curl.io to get your upload URL. transfer.sh got it right.

http://purrrl.link generates the links automatically if you are uploading via the CLI.
