Show HN: Sub-millisecond VM sandboxes using CoW memory forking
Summary
Zeroboot presents sub-millisecond VM sandboxes for AI agents by using copy-on-write memory forking backed by Firecracker/KVM. Benchmarks show spawn latencies around 0.79ms (p50) and memory per sandbox near 265KB, enabling rapid, isolated execution environments. The project is a working prototype with accompanying SDKs, docs, and an Apache-2.0 license.
