Source 2 is a 3D video game engine in development by Valve as a successor to Source.
It is used in Dota 2, SteamVR Home, Half-Life: Alyx, S&box, and more. Elements of Source 2 are present in Counter-Strike: Global Offensive, such as Panorama UI.

Source 2 was first made public with the Dota 2 Workshop Tools Alpha in August 6th 2014 and formally announced by Valve in March of 2015 at the Game Developers Conference. It was then implemented into Dota 2 on June 17th 2015.
Valve has announced that Source 2 will be released to the public for free, and it will only take money should it be used for commercial products.

The engine is capable of rendering highly complex and well detailed scenes with minimal framerate drops, thanks to its new 64-bit support alongside Vulkan, allowing for better multi-core rendering and more efficient 3D rendering.

Support for 32-bit, OpenGL, DirectX 9, XAudio, and macOS versions below 10.14 were removed in 2021.
