About gameserve.rs

GameServe.rs is a server browser for modded Call of Duty clients. It reads the same master servers the clients themselves use, then puts every result in one list with player counts, maps, modes, locations and a connect address you can paste into the console.

It covers 18 titles across seven sources, from the 2003 original through to HorizonMW. Lists refresh every 20 seconds. Nothing here needs an account.

What the site does

One list, every client
The server browser holds all seven sources at once, so you can look for a full lobby without knowing which client runs which title.
Search and filters that stick to a URL
Filter by game, client, country, map or mode. Each filter has a real address, so a game page or a client page can be bookmarked or shared.
Connect strings you can paste
Every row carries the address and port in the same form the game console expects. Click it to copy.
Population history
Statistics track player counts and server counts over time, broken down by game, client, mode, map and country.
Zombies round records
High rounds reported by Zombies servers on World at War, Black Ops and Black Ops II are collected on the statistics page.
Favourites, stored on your machine
Starred servers are kept in your browser. There is no account to make and nothing to sign in to.

Clients the browser tracks

Each client keeps a different slice of the series playable. Follow a client for its live list, or a title for the servers running it right now.

IW4x is the long-running Modern Warfare 2 client, running its own master server and dedicated server list for the 2009 multiplayer.

AlterWare maintains clients for Ghosts, Advanced Warfare and Black Ops III, adding dedicated server browsing to titles that shipped matchmaking-only.

Aurora covers Modern Warfare Remastered and Infinite Warfare, restoring server browsing and co-op to both 2016 titles.

HorizonMW is the actively developed successor to H2M-Mod, adding multiplayer to the MW2 Campaign Remastered client.

CoD4x is a server and client extension for Call of Duty 4, and the reason 2007 CoD4 still has a populated server list.

cod.pm runs the master server list for the first three games in the series, which still run on their retail clients rather than a mod client.

Titles with a live list

The code column is the internal name the clients and this site’s API use for each title, which is handy when you are reading raw API responses.

Where the numbers come from

Every client publishes its own server list, as a master server or an API. GameServe.rs polls those sources and normalises what comes back into one shape: name, current map, mode, player count, slot count and address. The cycle runs every 20 seconds.

That means a short list is usually real. If a client’s master server is unreachable, its games drop out of the browser until it answers again, and a reload a minute later normally tells you which of the two happened. Locations come from the server’s IP address, so a server can be flagged in the country its host sits in rather than the one its community plays from.

Snapshots are kept over time, and the statistics pages are drawn from those. What gets recorded is what a server reports about itself.

Public API

The same data is available as JSON, free and without a key. Use it for a Discord bot, a status page or a community site.

Polling

Responses are cached, so asking more often than the 20 second refresh returns the same data. Current limits are listed in the docs.

Who runs it

GameServe.rs is built and run by HGMServers, a Call of Duty community and server host. It is a community project: the clients listed here are separate teams, and none of them are affiliated with this site.

Wrong data, a missing client, or a server that will not show up: report it in the HGMServers Discord.
