transpilatron 7.0.0

A tool for transpiling code from python to C using AI agents.

transpilatron

Write Python. Get a native C binary. No C knowledge required.

uvx transpilatron your_code.py

Benchmarks

Benchmark	Python	C	Speedup
Sieve of Eratosthenes (10M numbers)	0.526s	0.022s	24x
Selection sort (10K elements)	1.963s	0.033s	58x

Verified on the same machine. Same output. Fully static binaries.

How it works

transpilatron uses an AI agent to convert your Python project into C, compiles it (using -O2 or -O3 flags), and hands you a fully static binary. No runtime, no interpreter, no dependencies.

1. Reads your Python entry file and follows all imports
2. Transpiles the full project to C
3. Writes a Makefile and compiles with static linking
4. Drops the binary in out/

Requirements

Tool	Why
uv	Run transpilatron instantly with uvx
C compiler (gcc/clang) & make	Compile the generated C code into a static binary

All must be on your PATH before running.

Install

# Run without installing
uvx transpilatron your_code.py

# Or install globally
uv tool install transpilatron

On first run, the tool installs its dependencies, and asks you to authenticate with poolside.

Usage

uvx transpilatron your_code.py

The binary lands at out/<your_code>. That's it.

What it handles

• Pure Python logic → idiomatic C
• HTTP (requests, urllib3) → raw BSD sockets
• JSON → cJSON
• Threading → pthreads
• File I/O → POSIX syscalls
• Multi-file projects → one binary
• Detects and fixes common Python bugs during transpilation
• Supports many major Python libraries with C extensions by simply using their C backends or alternatives
• The system attempts to translate pure Python libraries as well

Limitations

• Linux and macOS only
• torch / tensorflow — not supported (aborts with a clear error)
• Some dynamic Python patterns (metaclasses, heavy monkey-patching) may not translate cleanly

Why uv?

uv is the fastest Python package manager on the planet. uvx lets you run any Python tool instantly without installing it. If you're not using uv yet, you should be.
