What is Source SDK?

The Source SDK is a comprehensive software development kit compiled by Valve Software, enabling users to create custom maps and modifications for the expansive Source engine. This powerful toolkit provides a robust framework for developers to unleash their creativity, extending the capabilities of popular Valve games such as Counter-Strike, Half-Life, and Portal. While the Source SDK serves as the primary development platform, Valve has also tailored specialized SDKs for select titles, including the Left 4 Dead Authoring Tools, the Left 4 Dead 2 Authoring Tools, and the Alien Swarm SDK. These game-specific SDKs share a strong resemblance to the Source SDK, yet offer unique features and functionalities optimized for their respective titles
