Hi HN, I built Sbox because I needed a way to run untrusted / agent-generated code without adding policy logic, scoring, or heuristics.

Sbox is intentionally "zero intelligence": - no code analysis - no allow/deny rules - no LLM involvement

It only provides strong isolation primitives, and assumes all code is hostile.

I’m using it as a building block for long-running agents and automation systems. Would love feedback from people who’ve built sandboxes or secure runtimes.
