lockdown
Lockdown is a general-purpose programming language that combines the positive characteristics of both "strongly-typed" and "dynamic" languages, giving the developer the choice about when and how these should be used. (by richardhills)
skybison
A fork of Instagram's experimental performance oriented greenfield implementation of Python. It features small objects; a moving GC; hidden classes; bytecode inline caching; type-specialized bytecode; an experimental template JIT. (by tekknolagi)

Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Python cruising on back of c++
The parent comment is referring to the primary Python interpreter and runtime, CPython, not to libraries. There are of course other Python implementations, but [the only C++ one](https://github.com/tekknolagi/skybison appears to be unsupported.

Faster CPython at PyCon, part one
Kind of! In my fork I run microbenchmarks on each PR. So you can see on, for example, https://github.com/tekknolagi/skybison/pull/456, that the change had a 3.6% improvement on the compilation benchmark. If you expand further, you can see a comparison with CPython 3.8. Unfortunately Skybison is still on 3.8.

Another NaN-based tagging strategy for dynamic programming languages
This is also the pointer tagging scheme from the Ghuloum paper. I did not design it. Another tagging scheme I did not design is the Skybison scheme, which uses 0bXXX...XX0 to tag integers and 0bXXX...001 to tag heap pointers. This makes heap reads very easy (bias by -1 in addressing mode).

wrench (tiny, fast, c-like interpreter): created a webpage and now looking for benchmark code
Skybison is a Python interpreter and I'm curious what the results look like. We also have some benchmarks in benchmarks/benchmarks.

Using Firecracker and Go to run short-lived, untrusted code execution jobs
If you take a look at the Skybison Python runtime, I would be happy to chat and help you poke around integrating it: https://github.com/tekknolagi/skybison

November 2021 monthly "What are you working on?" thread
I am, in fits and starts, writing a bytecode optimizer for Skybison that takes advantage of type information.
What are some alternatives?
When comparing lockdown and skybison you can also consider the following projects:
RustScript2 - RustScript is a functional scripting language with as much relation to Rust as Javascript has to Java.
protea - An in-progress programming language inspired by JavaScript.
cib - clang running in browser (wasm)
Generic-C-DataStructures - A repository for code I wrote while learning to implement generic data structures in C
aussieplusplus - Programming language from down under
The-Spiral-Language - Functional language with intensional polymorphism and first-class staging.
cinder - Cinder is Meta's internal performance-oriented production version of CPython.
tonic - An elegant language for script-kiddies and terminal squatters.
