A simple JS script to extract server loads from ProtonVPN's website. This is designed to be run a DevTools console.

pvpn-server-loads.js

// RUN THIS AT <https://protonvpn.com/vpn-servers/>

SELECTOR = "#collapseNLfree > div:nth-child(1) > ul:nth-child(1) > .list-group-item"; // Change this to change the servers listed, this defaults to the Netherlands free servers

// As Proton change their website design, this will likely need to be changed
freeServers = document.querySelectorAll(SELECTOR);

loads = Array.from(freeServers).map(elem => {
  const [name, load] = elem.innerText.split("Load ");
  return name.trim() + ": " + load.trim();
});
// This just sorts the servers numerically
ordered = loads.sort((a, b) => {
  // We extract the server number from between the `#` and the `:` (as in `NL-FREE#33: 71%`)
  const numA = a.substring(a.indexOf("#") + 1, a.indexOf(":"));
  const numB = b.substring(b.indexOf("#") + 1, b.indexOf(":"));
  return numA - numB;
});
list = ordered.join("\n");

// Get the fastest server by load
// We set an initial value of 200% to make sure we get something
// If all servers have the same load, this will just return the first server in the list
fastest = loads.reduce(([lowestLoadServer, lowestLoadVal], curr) => {
  const currLoadVal = parseInt(curr.substring(curr.indexOf(": ") + 2, curr.length - 1));
  const currLoadServer = curr.substring(0, curr.indexOf(":"));
  return currLoadVal < lowestLoadVal ? [currLoadServer, currLoadVal] : [lowestLoadServer, lowestLoadVal];
}, [null, 200]);
fastestMsg = `Fastest server is '${fastest[0]}' with a load of ${fastest[1]}%.`;

// --- OUTPUTS ---
// `fastest`: array with two elements (fastest server name, fastest server load as a percentage)
// `fastestMsg`: information about the fastest server, formatted for human reading
// `list`: a human-readable list of all servers and their loads
