We let untrusted code try to escape. Launching Monday

Running someone else's code is a leap of trust. We turned it into proof.

Four lines of Python vs rustbox:

- Read the password file → not found

- Reach the cloud's secret address → can't connect

- Become admin → not allowed

- Copy itself forever → stopped at 10

Every result comes back with proof of what the code tried and what stopped it. 8 layers of protection. About 70 ms.

Built for coding tests, hiring rounds and scoring AI models.

Launching Monday, Nov 2 → https://www.producthunt.com/products/rustbox?launch=rustbox
