At the time of writing this article, it had an all-time peak of 213,168 simultaneous players and 88,000+ players currently.

What is Source SDK – is it a game, tool, or software, why is it so popular and consistently on top charts? Here’s everything you need to know.

What is Source SDK Base used for?

Source SDK Base 2007 is a Source ‘Software Development Kit’ which is a freely available video game creation and editing program designed by Valve who is also the developer of Steam. So if this name popped up on Steam, there’s nothing to worry about – you may have used a mod that uses it.

It’s worth noting that this kit allows you to create mods and maps using Source, so they are the files you need to play mods. In case you want to play GTA 5 mods, you may discover files related to this on your PC. It is also the backbone for games like Portal and its sequel, CSGO, Half-Life 2, Team Fortress 2, and Garry’s mod.

Why is Source SDK Base 2007 Popular and Topping Steam Charts?

The biggest reason why you are seeing it in the Steam top charts is because of FiveM which is a GTA 5 roleplay platform (but it also includes other servers like survival, drift, racing etc). FiveM (GTA Mod) uses the app ID of Source SDK 2013 MP base.

Basically, if you wish to play multiplayer on customized dedicated servers, you will need to download the FiveM client. Once you’re loaded in, you can use custom cars, maps, weapons, etc. To run custom servers, FiveM uses Source SDK Base and because FiveM is so popular, sometimes the player count is higher than GTA Online.

And that’s the basis of why it has thousands of players and topping the charts on Steam regularly. It will continue to do so until GTA 5 RP servers are famous. If you are curious to know which are the most played and popular games in the world, here’s an article that you might want to check out.
