Most likely SOCKS5? At least in Firefox there's builtin UI for configuring it separately from OS. Chromium is more annoying and needs command line flags.
They claim to use wireguard, which might be something a browser extension can start on-demand?

AFAIK, there's still no proper SOCKS user authorization. So if I do something like that on my own VPS, I'll quickly have like 10 000 open connections from Pakistan there.

Yes, also extensions like FoxyProxy.
SOCKS4/5 configuration in Firefox is a pure joy. Adding a Putty tunnel there is probably the only simple way to achieve what I described in the comment above.
Add a dynamic tunnel there.
Start the session.
Then enter 127.0.0.1 and the port you've chosen as a SOCKS v5 proxy in Firefox options.
Congratulations! Your poor man's VPN is ready :)
