Best CS Source servers right now
Counter-Strike: Source runs on the Source engine and lives almost entirely on community servers. The in-game browser shows you what is online this second; a CSS server list like GTScope adds rankings, history and votes, so you can tell a server that is full every night from one that got lucky once.
Start with the top 10 CS Source servers, ranked by real players and monthly votes, then filter by mod below.
- Pick your mod first. Surf, zombie and classic public servers are different games.
- Keep the ping low. Movement mods like surf and bhop need a server close to you.
- Read the map name.

How to promote your CS Source server for free
A CSS server competes with servers that have been running for fifteen years. This is how to promote a CS Source server for free:
- Add your CSS server on the Add Server page with its IP and port.
- Claim it, set its modes (Surf, Zombie, GunGame…) and add your Discord, so players filtering by mode find you.
- Put the live banner on your website, Steam group and Discord.
- Ask your regulars to vote every month to climb the CS Source ranking.
- Turn on Discord alerts so you know about downtime before your players do.
Tip: SourceMod and Metamod:Source power most CSS mods. Keep them updated after game updates, or the server can crash on map change and drop off every list until it is back.

How CS Source servers are tracked
Counter-Strike: Source servers answer the standard Steam server query (A2S) on their game port. GTScope sends it about every 5 minutes and reads the server name, current map, players, slots and the names of the players connected. The busiest CS Source server on GTScope has more than 60 players online at once.
