Transpilatron

Transpilatron is an open-source AI agent that converts Python source files into fully static C binaries with a single command: `uvx transpilatron your_code.py`. The agent reads the file, transpiles Python to C, compiles the result, verifies correctness with Valgrind, and produces a binary that carries no interpreter, no runtime, and no external dependencies. The entire pipeline runs autonomously — you give it a `.py` file, you get back a native executable.

The differentiating claim is the static binary guarantee. Where tools like PyInstaller bundle the interpreter and Cython compiles extension modules that still depend on CPython, Transpilatron targets a binary that runs on a machine with no Python installed at all — relevant for scratch containers, initramfs images, and embedded deployments where pulling in a runtime is not an option. The Flask-to-C-HTTP-server demo in the repo illustrates the scope: a five-route Flask app becomes a native HTTP server with one command, no Flask dependency in the output.

The scope is also the constraint. The agent can model Python that maps cleanly to C constructs: arithmetic loops, simple data structures, function calls, basic HTTP routing. Code that leans on the Python object model, dynamic attribute access, metaclasses, or third-party libraries outside the tool’s translation vocabulary stops the pipeline. There is no documented list of supported constructs — you discover the boundary by running it. Teams with compute kernels or tightly scoped CLI tools land inside that boundary; teams with general-purpose application code find it quickly.
