I built a self-hosted code execution runtime (because I needed one)

At some point, if you’re building dev tools, automation platforms, or anything with plugins or AI-generated logic, you hit the same wall: «You need to run user-provided code.» Not just your code — their code. And that’s where things get scary 😅 The naive version At first it looks simple: result = run(user_code) return result And yes… this works. Until someone uploads: an infinite loop a memory bomb file access network abuse or just crashes your process Then you realize: executing code is easy — executing it safely isn’t. Why I built GozoLite I needed something that could: run arbitrary code not crash my app not access my system not interfere with other users be self-hosted be simple to deploy Most options I found were either: too unsafe too heavy (full orchestration) or external SaaS So I built a middle ground: a lightweight self-hosted execution runtime. The idea is simple Instead of running code inside your app: API → GozoLite → isolated container → result Each execution: runs in iso
