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.

bsdutils: Alternative to GNU coreutils using software from FreeBSD
For fun, I ported much of BSDutils to WebAssembly. Code [1] and live demo [2]. It was much, much easier porting BSDutils than GNU coreutils, since the source code is often much smaller, and hence easier to read and understand with simpler dependencies.

SQLite 3.40.0 with WASM Support
For what it is worth, I also care about building this with zig. https://github.com/sagemathinc/cowasm/blob/main/packages/sql...

Adding Python support using Pyodide to our low-code framework which supported only JavaScript.
If it fits your needs and is working, then fine. Please remain aware of a different approach to what pyodide is doing based on perceived weaknesses in pyodide.

CoWasm: An alternative to Emscripten, based on Zig (demo: Python in the browser)
CoWasm supports WASI right now via this library https://www.npmjs.com/package/wasi-js, which I actually develop as part of CoWasm . One unusually thing I did, which goes beyond what emscripten does, is I implemented a quite a bit of posix functionality, often by writing extension code to nodejs and calling it from Javascript, because there's a lot of POSIX that Node.js doesn't expose. This only works on Mac and Linux and is also available standalone in this library https://www.npmjs.com/package/posix-node, which is implemented in Zig. You can get a sense of the scope of POSIX functionality that goes beyond what WASI defines here: https://github.com/sagemathinc/cowasm/tree/main/packages/ker...
One motivation for doing this is to try to get the full Python test suite to pass, including all the functionality that involves subprocesses, posix calls, etc. I've only got to about 85% at this point. It can be a ton of tedious work, but at least Zig helps impose some discipline (e.g, it doesn't let you ignore handling errors until later), and makes it easy to test compilation for all supported targets on every change (due to excellent cross compilation support).

CoWasm: An alternative to Emscripten, based on Zig (demo: Python in the browser)
Yes, porting https://SageMath.org to the browser is part of the plan, and this is a key foundation for that. I ported some of the components of Sage (e.g., https://libntl.org/) already as part of https://github.com/sagemathinc/jsage, and I don't see any fundamental obstruction to porting all of Sage, except time. It would be great if once CoWasm is more stable, I can get some help porting some components to WASM.

Tiny WASI – A tiny WASI runtime written in TypeScript
And here is the more lightweight and flexible (in some ways) one from Wasmer, before they completely rewrote it in Rust:
https://github.com/sagemathinc/JSage/tree/main/packages/wasi
It took me some work to track down the old version, fix some bugs in it, and keep it going. But I personally find the old version very useful too, and if you can see from the comments that it has an interesting history.
