Launch HN: Freestyle: Sandboxes for AI Coding Agents (freestyle.sh) AI

Launch HN’s Freestyle describes a system for running AI coding agents inside full Linux VM sandboxes, including creating per-agent repos from templates, forking VMs, and executing build/test/review workflows. The post highlights fast VM startup, live forking and pause/resume (to reduce cost while idle), and features like bidirectional GitHub sync and configurable webhook triggers. Freestyle positions its approach as real VMs (not containers) with strong isolation and support for multiple virtualization layers.
