Screenshot of the now-deprecated "Source SDK" launcher.
If you see this page when you first open the "Source SDK" (AppID 211) launcher, please note that the standalone Source SDK tool/launcher is no longer updated, and does not support Source 2013 and Team Fortress 2 branch games.
The deprecated Source SDK tools are provided to create content-based mods for Source 2009 or earlier, and to obtain source code & create or maintain legacy mods built on Source SDK Base 2006 and Source SDK Base 2007.

Many Source 2013 and Team Fortress 2 branch games are usually shipped with Source SDK preinstalled, located in the 🖿\bin folder. To launch the SDK applications (Hammer, HLMV, etc...) manually on Source 2013 games, see the SDK Installation - Source 2013 (SteamPipe) & TF2 branch section for a list of applications and their executables.
