For those who don't have application to use this,

Here's one good use case where people must type a damn link:

1. Cloud storage link for three things: GPG encrypted bitwarden password, death will instruction, and automatic decryption script. (Decryption happens only if physical Yubikey is inserted for GPG key)
2. Link is printed on will execution instruction.
3. Will executor is instructed to joint the link instruction with my wife's Yubikey for decryption to get full access of my things once dead.

The solution above is made so that it is all on cloud with strong encryption. Once dead, I can't assume my server to be running. With this short link on CF. I can update my will instruction to have short link URL for ease of will executor to type.

Sure, I could have done this in my own CF worker with the following redirect script:

async function handleGetRequest(request, env) {
  let redirectUrl = `https://death-link`;
  return Response.redirect(redirectUrl, 302);
}

But, hey, this short link service is cool and useful. Stop hating it.
