Show HN: Bhatti — Self-Hostable Firecracker MicroVM Orchestrator with Auto Pause/Wake for AI Agent Sandboxes

Bhatti / Hacker News·medium signal

Bhatti (bhatti.sh) provides Firecracker microVM orchestration purpose-built for AI coding agent sandboxes, with a thermal manager that auto-transitions idle VMs from hot to warm (30s, ~400μs resume) to cold (30min, snapshotted to disk, ~50ms resume). Each sandbox is a real Linux VM with kernel-level isolation, and any API request transparently wakes cold sandboxes. Multi-tenancy with per-user API keys and rate limiting. 17 points on HN, early but architecturally relevant for agent infrastructure.
