The Blender Foundation, operating under the aliases Blender and Blender Institute, is a Netherlands-based organization renowned for developing and maintaining Blender, a comprehensive open-source software suite for 3D computer graphics. Its core product supports a wide array of creative disciplines including 3D modeling, animation, simulation, rendering, video editing, and game creation, serving a global community of artists, designers, educators, and developers. The foundation provides critical infrastructure to support this ecosystem, such as developer forums, wikis, documentation portals, and git repositories for collaborative software development. Additionally, it operates a cloud-based training platform, further extending its educational outreach. This open-source model distinguishes Blender within the competitive landscape of 3D content creation tools, fostering a community-driven approach to software evolution and accessibility.

The scale of Blender's operational footprint is evidenced by the significant cyber incidents it has faced. In November 2023, its primary website and associated services endured a massive distributed denial-of-service attack that generated over 1.5 billion malicious requests at peak volumes of 100,000 per second, causing multi-day outages. This event underscores the high traffic and global reliance on its platforms for downloads and community interaction. A prior hacking attempt in March 2021 targeted the main website subdomain, triggering maintenance mode, while core services like the developer portal, wiki, and git repositories remained operational, demonstrating a resilient infrastructure design. The organization's structure includes the Blender Institute as a known alias, though explicit details regarding ownership or subsidiary relationships are not provided in the available information. These incidents highlight the essential role its digital infrastructure plays for a worldwide user base, with no reported compromise of user data or software integrity during either event.
