Source 2 Viewer is a free, open-source desktop tool for working with Source 2 game files. It is designed for modders, map creators, texture artists, 3D artists, researchers, and others who need to inspect, extract, convert, decompile, or repack assets. VPK archives can be browsed through tree and list views, with support for extracting individual files, folders, or complete archives. The supported scope includes maps, models, materials, textures, sounds, particles, physics, animations, shaders, navigation meshes, closed captions, and KeyValues.

Its strongest feature is the combination of asset inspection and conversion depth. The Windows GUI provides 3D viewing for maps, models, physics, particles, materials, and textures, along with built-in audio playback and waveform visualization. Models, maps, physics, and animations can be exported to glTF or GLB, while textures can be exported to PNG, JPG, or EXR. The tool also decompiles maps, models, and materials into editable formats, and can inspect and convert compiled shader packages. For repeatable workflows, batch extraction and command-line automation extend the tool beyond individual file browsing.

Platform fit depends on the workflow. The documented GUI is Windows-only, while the command-line utility runs on Windows, Linux, and macOS for automated extraction and conversion. Source 2 Viewer can also create and save new VPK archives, making it useful for users who need both unpacking and repacking capabilities. It is a strong choice for Source 2-focused asset work, especially when command-line processing or detailed resource inspection matters. Users seeking a general-purpose extractor outside Source 2 formats, or a cross-platform graphical 3D application, should consider a different type of tool.
