features	title details ⚡ Ultra-fast Startup Resource pooling and snapshot cloning skip all cold-start overhead. Sandbox creation faster than a blink. title details 🔒 Hardware Isolation Every sandbox runs a dedicated OS kernel in its own MicroVM. title details 🔌 E2B SDK Compatible Drop-in replacement for E2B Cloud. Switch by changing one environment variable — zero client code changes. title details 📦 High-density Deployment MB-level per-sandbox overhead enables thousands of instances per server via kernel sharing and Copy-on-Write. title details 🛡️ Network Security eBPF-based inter-sandbox isolation and egress filtering at kernel level; built-in L7 security proxy enables per-domain/path/method policies with automatic credential injection — secrets never visible to sandbox code. title details 📸 State Management Create checkpoints on running sandboxes, roll back to any saved state, or fork into parallel exploration environments at millisecond granularity.
