A uv-NATIVE BUNDLER

Pack a Python
project into one file,
after hours.

moonlit is a CLI that bundles a uv-managed project — or an entire uv workspace — into a single self-contained zipapp per PEP 441. No installer. No venv on the host. One .pyz and a Python.

$ uv tool install moonlit COPY

01 / WORKSPACE-AWARE

Bundles uv workspaces

Walks the workspace graph from pyproject.toml, resolves every member, and packs the closure your entry point actually imports.

02 / FAST

Builds in seconds

Uses uv's resolver and a streaming zipfile writer. A 40-package workspace lands in under a second on a warm cache.

03 / ONE FILE OUT

Single .pyz, no runtime

Output is a stdlib zipapp per PEP 441. Drop it on any host with a compatible CPython — no venv, no installer.
