mgit — a sandboxed, checkpointed working substrate for LLM coding agents

mgit gives a coding agent two things together: containment — its untrusted code (npm/pip installs, builds, tests) runs in a disposable per-task microVM, not on your machine — and a checkpointed working substrate — every step is a task-tagged micro-commit in an isolated .mgit store that never touches your real .git, so you review and land only the squashed result.

Beta. The microVM sandbox is the differentiator; it is live-validated on Linux (firecracker/KVM) and macOS (Apple Virtualization.framework, arm64). Windows runs core mgit without the sandbox. See Known limitations in the CHANGELOG.

Highlights

  • Per-task microVM containment — installs/builds/tests run in a disposable, hardware-isolated VM; a poisoned dependency burns the VM, not your host. Default-deny per-task egress allowlist; verified land (dual-hash + task binding + host-anchored attestation) through an airlock.
  • mgit work — one command starts an agent on a task: a task-bound worktree with the agent's shell wired through mgit run into the sandbox.
  • Runs over your existing git repo — a self-contained .mgit store; your project's .git is provably never mutated, and the base stays in sync with your local working state automatically (no manual sync).
  • Checkpointed, reviewable history — task-tagged micro-commits; backtrack / fork / cherry-pick to course-correct; squash --to-git | git apply lands a byte-for-byte patch.
  • Multi-agent worktree isolation, REST + MCP integration surfaces, dual-hash integrity, append-only audit.
  • Pure Go, zero CGO — single static binary (Linux, macOS, Windows; amd64 + arm64).

Quality

  • 530+ automated tests, race-detector clean under -race, zero lint warnings.

Pairs with mtix

mgit + mtix form a closed loop for enterprise AI-driven development: mtix tracks what to build, mgit tracks what was built. Task IDs flow between both systems. The unit of failure is a task, not a session.
