I built a Python -> C transpiler. Then it transpiled itself. A developer built Transpilatron, an AI agent that transpiles Python code into fully static C binaries, achieving speedups of up to 58x on benchmarks. The tool successfully transpiled its own source code into a working C binary, and can convert Flask apps into native C HTTP servers with no Python runtime. Transpilatron is designed for environments like initramfs and scratch containers where no interpreter is available. A few weeks ago I needed to run Python scripts in initramfs — the tiny Linux environment that exists before your actual OS boots. No interpreter. No dynamic linker. Nothing. So I built Transpilatron : an AI agent that takes Python code and produces a fully static C binary. uvx transpilatron your code.py That's it. No C knowledge required. First, does it actually work? I ran two tests: | Benchmark | Python | C | Speedup | |---|---|---|---| | Sieve of Eratosthenes 10M numbers | 0.526s | 0.022s | 24x | | Selection sort 10K elements | 1.963s | 0.033s | 58x | Same output. Verified on the same machine. The C binary is fully static — no runtime, no interpreter, no dependencies. Then I tried something more interesting. A 14-line Flask app: python from flask import Flask app = Flask name @app.route '/' def hello : return 'Hello from the webserver ' @app.route '/ping' def ping : return 'pong' if name == ' main ': app.run host='0.0.0.0', port=8080 One command: uvx transpilatron web.py Output: a native C HTTP server. No Flask. No Python runtime. bash $ curl http://localhost:8080/ Hello from the webserver $ curl http://localhost:8080/ping pong Verified memory-safe by valgrind: 0 errors, 0 leaks. Here's where it gets weird. Transpilatron is written in Python. So I pointed it at its own source code: uvx transpilatron src/transpilatron/agent.py The agent read its own Python source, wrote 400+ lines of C, fixed its own compiler errors autonomously, ran a memory audit, and produced a working binary. $ ./out/agent --help Usage: ./agent --minimal|--full
