nginx is available on Windows and it can be done like this, nvm.

I also admit that I haven't done any testing on Windows because I can't afford a Windows Server license. If this really matters to you, please open a ticket.

You can get an evaluation version of Windows Server, also Anubis compiles fine for Windows in MSYS2 with mingw-w64-go.

I also have managed to make anubis work on an Windows nginx server and can confirm it works fine. Thanks to @MichaelAgarkov for the help.

I am putting my findings here in the hopes that this will be of help to others:

1. Compile Windows executable binary of anubis from anubis-src-vendor-npm by running make prebaked-build on a Git Bash.

2. Run anubis.exe with -help for a usage help. Run anubis.exe with any settings that you might need, such as -use-remote-address.

3. (for nginx Windows) Configure nginx.conf: In the front server, set listen 443 ssl;, and location / { proxy_pass http://anubis/; }. Insert ssl and other reverse proxy configuration.

4. Create a block upstream anubis { server 127.0.0.1:8923; }. Create a backend server at listen 127.0.0.1:3923; and put your server configuration in that block.

5. Confirm anubis is working by accessing your server from another network.

Thank you for the anubis, @Xe.
