I'm Evan, CTO of Ito (ito.ai). We do code review that actually runs your code. When we're developing locally, we run lots of coding agents in parallel against the same repo, and we kept hitting the same wall: git worktrees isolate files, but the database, ports, and services all collide.Moo is a brand new internal tool we use to moove faster and thought we'd share it.Every branch or agent attempt gets its own isolated Linux machine, and the machine's state is versioned with your repo. Moo save snapshots the runtime tagged with the current commit. Check out an old SHA, run moo new, and you boot the exact runtime that existed there.It's microVMs with copy-on-write (CoW) disks under the hood. Forking a 20 GB environment is <500ms.Right now it's only macOS Apple Silicon only due to depending on libkrun and APFS clonefile.

Could you build this?
No Developing a tool that snapshots and isolates entire developer machines, ephemeral databases, network namespaces, and services alongside Git worktrees requires deep operating system and container virtualization engineering.
What it would actually take: A tool like Moo requires low-level systems programming (likely in Go or Rust) interfacing directly with Linux kernel features like cgroups, network namespaces, and overlay filesystems (OverlayFS/btrfs/ZFS snapshots), or coordinating with container engines and macOS hypervisors. It must manage dynamic port remapping, local proxy routing, and stateful volume cloning for databases with minimal latency and footprint. This demands deep expertise in systems administration, OS virtualization, and distributed systems.
