Yep! Depending on what your home connection looks like, you have a few options:

if you are lucky enough to have your own private IP-address and are able to open ports, then you’re almost done already – you can put copyparty on some port (or keep the default 3923), and then anyone could connect to it by going to your.ip.address:3923

(with this approach, you will want to create your own HTTPS certificate so the traffic is properly encrypted – the best option here is to get a domain and get a certificate for the domain)

however, if you are behind CGNAT, meaning your internet provider has given you a shared IP-address, then people cannot connect directly to your home-PC. One way around that issue is by setting up a machine somewhere on the internet which bridges the gap back home to your PC. Cloudflare offers this as service, and this is explained in the copyparty readme – see the “at home” section for one way to do that.

if you are against using Cloudflare for idealistic reasons (they are becoming quite powerful since they run a whole lot of the internet), then you can set up a cheap VPS which serves the same purpose. That’s my setup, and how you are accessing the copyparty demo server right now – I have the cheapest VPS you can get from Hetzner. The VPS is running nginx, and it forwards the traffic to my homeserver through an SSH tunnel. I haven’t documented this approach in the copyparty readme, but I have a feeling a lot of other people have :>
