lypning, a three-tier Python runtime for coding agents
A Rust dispatcher runs short Python snippets through a lightweight subset, MicroPython, or CPython, choosing the cheapest interpreter that can handle each program.
Why it surfaced
lypning is built around a very specific pressure point: the disposable Python one-liners emitted by coding agents. Its homepage publishes the mechanism and the caveats, including a corpus of 842 captured programs, zero mismatches for the full mixture in its conformance test, and a refusal protocol designed to make fallback predictable.
