About

Sometimes, you just need to send someone a file, and don't want to stand up a whole webserver.

While this tool won't help you bypass NAT or anything like that, it does solve the initial issue.

Simply point this tool at one or more file(s), and it will generate URLs others can use to download them.

It also accepts input via stdin, optionally in combination with filenames.

Filenames are prefaced by a randomly generated slug, of configurable length. Set -l|--length to 0 to disable this.

If so inclined, you can also optionally obfuscate filenames with the -r|--randomize flag.

Static binary builds available here.

x86_64 and ARM Docker images of latest version: oci.seedno.de/seednode/send:latest.

Dockerfile available here.
