What is SPy?

TL;DR: SPy is a variant of Python specifically designed to be statically compilable while retaining a lot of the "useful" dynamic parts of Python.

It consists of:

1. an interpreter (so that you can have the usual nice "development experience" that you have in Python)

2. a compiler (for speed)

The documentation is very scarce at the moment, but the best source to understand the ideas behind SPy are:

• blog post Inside SPy, part 1: Motivations and Goals

• PyCon Italy 2025 talk: slides and recording.

• PyCon US 2024 talk: slides and recording.

Additional info can be found on:

• Antonio Cuni's blog
• A peek into a possible future of Python in the browser by Łukasz Langa.
