Unlike containers that share host kernels or VMs that bundle full kernels, LiteBox uses a library OS model with narrow interfaces. It features a split architecture with North (POSIX system calls) and South (host connection) interfaces, supports AMD SEV-SNP for confidential computing, and can run unmodified Linux applications across different platforms. The project is experimental and not production-ready, positioning itself as a middle ground between containers and VMs for scenarios requiring stronger isolation without heavy overhead. ## Full article daily.dev links to this article rather than hosting it.
