Launch HN: Freestyle: Sandboxes for AI Coding Agents
Not a pilot. Freestyle just launched sandboxes that fork full VM memory in 400ms—purpose-built for AI coding agents at scale.

Why it matters
Freestyle is addressing a critical infrastructure gap for AI agents: they need full compute environments that rival human developer setups but provision in seconds. By building bare metal infrastructure, they're enabling the next generation of coding agents to handle complex, stateful tasks that serverless platforms can't support.
The key facts
6 to know400ms horizontal sandbox fork with full memory preservation
~500ms sandbox startup time
Full Linux + hardware virtualization support (eBPF, Fuse, systemd)
Bare metal infrastructure investment to avoid AWS/GCP bare metal monthly cost premium
Targets multi-tenant AI agent infrastructure at scale
YC-backed (Launch HN post)

Publisher excerpt: We’re Ben and Jacob, cofounders of Freestyle (https://freestyle.sh). We’re building a cloud for Coding Agents. For the first generation of agents it looked like workflows with minimal tools. 2 years ago we published a package to let AI work in SQL, at that time GPT-4 could write simple scripts.…
