Show HN: Sanbox, batteries included sandboxes for AI agents

Hi HN,

We are building Sanbox, a platform for running AI agents in isolated and resumable sandboxes.

We use the OpenCode SDK as the harness, support reusable templates, and have a CLI that works with Codex, Claude Code, Cursor, CI, or your terminal. Each sandbox has MicroVM isolation, a persistent filesystem, and live trail of run events. Can also self-host if required for security/compliance.

It's on the roadmap to add network ACL, secrets managements, LLM cost tracking & observability.

We are also happy to build custom integrations or triggers for specific use cases. For example, spinning up a sandbox from a database edge function when data changes, or connecting Sanbox to an email inbox for complex workflow processing.

It is still early, you can sign up to try here: https://sanbox.cloud
