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.cloudMy email is also on my profile here.

Could you build this?
No Providing secure, multi-tenant, sub-second microVM infrastructure with persistent storage, virtual networking policies, and secrets management requires heavy cloud infrastructure engineering.
What it would actually take: Building this platform requires a stack based on Firecracker or Cloud-Hypervisor microVMs on bare-metal servers, orchestrating rapid snapshot restore, overlay network isolation (eBPF/wireguard), and persistent distributed block storage. The hardest parts are sub-second cold starts, bulletproof multi-tenant kernel isolation, and safe memory snapshotting under active workloads. This necessitates deep Linux kernel, hypervisor virtualization, and infrastructure systems engineering expertise.
