- Developers running untrusted code on Linux hosts
- Worth noticing
- The docs report placing 200 files 7× faster and reading them 49× faster than a microVM runtime on the same machine.
Field notes
The documentation includes a `doctor & setup` section and separate guides for commands, workspaces, resource limits, isolation, and reclamation. Its example API creates a named sandbox, writes a file, executes a command, reads stdout, and removes the sandbox. The page says idle-stop and maximum-lifetime settings are recorded on the container, allowing them to outlive the process that configured them.
