I just tried using the platform and it looks really interesting. However, I ran into a small issue while using it. Is there a guide or help page I could check?

Hey community! I built tethered because Python has no built-in way to restrict outbound network access at runtime. One function call, zero dependencies — declare an allow list and any socket call outside it is blocked before a packet leaves the machine. Uses Python's audit hook system (PEP 578), no monkey-patching or proxies. Built it mainly for supply chain defense (compromised deps can't phone home), AI agent guardrails, and test isolation. Works with requests, httpx, aiohttp, Django, FastAPI — anything built on Python sockets. Fully open-source (MIT). Would love your feedback!
