# runc vs CubeSandbox

runc and CubeSandbox share 3 technologies: containerd, github.com/sirupsen/logrus, and github.com/coreos/go-systemd/v22. Both are written in Go.

- [opencontainers/runc](https://seerepo.com/r/opencontainers/runc): CLI tool for spawning and running containers according to the OCI specification
- [TencentCloud/CubeSandbox](https://seerepo.com/r/TencentCloud/CubeSandbox): Instant, Concurrent, Secure & Lightweight Sandbox for AI Agents.

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
