  `Freestyle`, sandbox infra for coding agents with **~500ms** boot and memory-level forks

  FreestyleSandbox infra — live memory fork for coding agents

  A full Debian VM can boot in ~500ms and fork the entire running state with about 400ms pause. Useful if you want agents to branch, snapshot, and resume real dev environments instead of toy serverless sandboxes.

  • —State cloning is not just filesystem copy: browser scroll, running processes, and in-memory errors carry over, which makes agent branching and rollback much more practical.
  • —The stack targets full Linux compatibility with hardware virtualization, eBPF, FUSE, multiple users, and systemd, so tools expecting a normal Debian box should need fewer hacks.
  • —They moved to bare metal because cloud node migration performance was not good enough. That hints this category may become infra-heavy and margin-sensitive fast.
  • —Positioning is closer to 'EC2 for agents' than lightweight preview sandboxes. The differentiator is runtime continuity, not just quick spin-up.

  `Freestyle`: cloud sandboxes that fork live coding-agent state

  FreestyleSandbox service — live forks full running machine state

  This targets a real bottleneck in agent infra: preserving full machine state, not just files. ~500ms boot and ~400ms live-memory fork make branch-and-retry workflows much more practical, though pricing and reliability are still the real filter.

  • —Instead of stateless runs, it clones full VM memory with browser scroll position, running processes, and errors intact; that enables true agent branching.
  • —Boot time is quoted at ~500ms, with horizontal fork pauses under 400ms. Fast enough for iterative agent loops, previews, and parallel debugging.
  • —The stack is closer to full Debian VMs than lightweight containers: hardware virtualization, eBPF, FUSE, multi-user support, and systemd init are all supported.
  • —They moved to their own bare-metal racks after cloud-node mobility underperformed. That signals high infra ambition, but also heavier ops risk.
