m0serve

A WSGI/ASGI server for Python applications, written in Mojo. Point it at a Django, Flask, FastHTML or Starlette app and it serves it — no Mojo toolchain required, no compilation step, nothing to configure.

pip install m0serve
m0serve myproject.wsgi:application

The protocol is detected from the object, so the same command serves WSGI and ASGI. m0serve --help lists the flags; --workers N, --threads N (on free-threaded CPython) and --blocking-threads N are the topology ones.

What is in the wheel

One compiled binary and the Mojo runtime it loads. No CPython — m0serve resolves libpython at run time from the interpreter it is installed beside, which is why there is no ABI tag and one wheel per platform covers CPython 3.10 through 3.14, free-threaded builds included. It has no Python dependencies and fetches nothing at install time.

Install it into the same virtual environment as your application, the way you would gunicorn or uvicorn; the console script points the embedded interpreter at that environment.

Platforms

platform	status
macOS arm64 (Apple Silicon)	supported
Linux x86_64 (glibc)	supported
Linux aarch64	buildable, not yet shipped
macOS x86_64 (Intel)	not possible — Modular ships no Intel Mac toolchain
musl / Alpine, Windows	not supported

The wheel's filename carries the exact macOS and glibc floors it was built against. On an older system pip declines to install it rather than installing something that crashes.

Status

Pre-1.0 and deliberately small: HTTP/1.1 only, no TLS, no HTTP/2 — terminate at a proxy, which is gunicorn's answer too. The API will change before 1.0.

Licence

MIT, and the wheel redistributes third-party components under their own terms — the Mojo runtime (Apache-2.0 with LLVM Exceptions) and a fork of lightbug_http (MIT). Full text and attribution ship inside the wheel; see NOTICE.txt beside the installed package.
