Re:Show HN: Hotcell – local sandboxes for AI agents

this looks awesome! i built something similar called shuru.run. it follows the same idea of minting and passing a random key instead of your actual keys inside the sandboxes. the key only gets swapped when it reaches the gateway running on the host. great work!

That means you can seek anywhere in the timeline, and exports are frame accurate without needing a server.Demos (each includes its own source):...

Show HN: Run coding agents in microVM sandboxes instead of your host machine
https://github.com/superhq-ai/superhq
Hi HN, we built SuperHQ, an open source app that runs AI coding agents in isolated microVM sandboxes instead of directly on your machine. Each agent gets its own VM with a full Debian environment. You mount your projects in, writes go to a tmpfs overlay so your host is never touched, and you get a diff view to accept or discard changes. API keys never enter the sandbox. We also just launched...
