We are actually the team behind the CubeSandbox project. Over the past few months, as we scaled our internal AI Agents, we hit quite a few bottlenecks with existing execution environments (like massive memory overhead and slow boot times). So, our team decided to build our own. After months of grinding, building upon RustVMM and KVM, we set out to create CubeSandbox . Through a lot of custom engineering and aggressive refactoring, we finally achieved some major technical breakthroughs. Our goal is to bring the community a faster, more efficient, out-of-the-box secure sandbox service. We'd love for you all to check it out, give it a spin, and let us know what you think!
