Show HN: Agentjail – Self Hosted Freestyle.sh

Category: devtools

Tags: sandbox, security, rust, containerization, ai-agents

Score: 8.3/10 (Innovation: 7, Technical: 9, Documentation: 9, Utility: 8)

Agentjail is a minimal, rootless Linux sandbox for securely executing untrusted code, built in Rust. It's particularly interesting for its comprehensive security layering (namespaces, seccomp, cgroups v2), advanced features like live forking and network allowlisting via a built-in proxy, and its specific targeting of AI agent and build system use cases.

Target audience: devops, backend devs, ai-ml engineers
