Mesa 3D Graphics Library

Mesa is an open-source implementation of the OpenGL, Vulkan, and other graphics APIs, providing drivers and a software rasterizer for systems without dedicated GPU hardware. Created by Brian Paul in 1993, Mesa has over 3,000 stars as of 2026 and is the most important open-source graphics project in the Linux ecosystem, with major contributions from Intel, AMD, Red Hat, Google, Valve, and Collabora. Mesa provides graphics drivers for virtually all Linux systems using Intel, AMD, and ARM GPUs, and is used by Steam Deck, Chrome OS, Android, and every major Linux distribution. Key features include: OpenGL implementation (OpenGL 4.6, OpenGL ES 3.2, and WebGL 2.0 via Gallium3D drivers), Vulkan implementation (Vulkan 1.3 with open-source drivers including ANV for Intel, RADV for AMD, Turnip for Adreno, and PanVK for Mali), Gallium3D driver architecture (modular framework between hardware drivers and API state trackers), Zink (OpenGL on top of Vulkan), software rasterizers (llvmpipe for high-performance software rendering using LLVM JIT, softpipe for reference, lavapipe for software Vulkan), NIR (Nova IR intermediate representation for shader compilation across all drivers), hardware video decode (VA-API and VDPAU state trackers), and OpenCL support (Clover and rusticl implementations).
