Ask HN: What are agent sandboxes missing?

4•oryx1729•1h ago
I'm building an agent sandbox platform with opinionated customizable templates for general purpose agents using the OpenCode SDK.

The idea is to provide a great CLI experience so it's easy to use an AI client like Claude Code or Codex to launch sandboxes, fetch/retrieve data and prompts, review generated outputs, and manage queues for ask-user questions.

I also plan to add an AI gateway layer, similar to Tailscale Aperture(not affiliated but one of their engineers gave a great talk at AI Engineer it's on YT) for monitoring network access, distributing secrets, and controlling what services/systems a sandbox has access to.

For people building agent workflows, I'd love to hear feedback if you've tried other sandbox solutions.

What was missing and what was the hard part?

Docker sandboxes do that. They take quite bit of resources though, almost same as a standard VM.

I need to mount directories or remove after creation easily, like I do with containers.

Gateway would be good too.

Firewall needs more functionality.
