Building a Linux Container Runtime from Scratch
We're open sourcing our programmatic low-level container runtime, Styrolite
Importantly, we designed Styrolite with full awareness that Linux namespaces were never intended as hard security boundaries—a fact that explains why container escape vulnerabilities continue to emerge. Secure microservices: Within Edera Protect, Styrolite enables fine-grained container isolation for security-critical workloads Application sandboxing: Our companion tool, styrojail, helps Linux users limit resource consumption and improve security for applications like web browsers that process untrusted input Custom CI/CD environments: Developers can use Styrolite to create isolated build environments with precise resource controls Our security-first design acknowledges the inherent limitations of Linux namespaces while providing a more robust foundation through careful defaults and explicit security controls.
