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.

CoWasm: An alternative to Emscripten, based on Zig (demo: Python in the browser)
This is a slim alternative to Emscripten which focuses only on the C/C++ <=> JS interoperability part:

From a WebAssembly Perspective
There's actually a super interesting project called wajic here:
https://github.com/schellingb/wajic
It's basically clang plus wasm-opt and some magic pixie dust which enables some of the most important features of Emscripten, but without the whole 'technology zoo' :)
- Zig and WASM

WebAssembly and C++
There's now an interesting alternative to Emscripten called WaJIC:
https://github.com/schellingb/wajic
Enables most of the "Emscripten magic" (like embedding Javascript code into C/C++ files), but in a more bare bones package (apart from clang it essentially just uses the wasm-opt tool from Binaryen for post-processing).
(to be clear, wajic has fewer out-of-the-box features than Emscripten, but it might be an alternative for very small projects which don't need all the compatibility shims which are coming with Emscripten, while still providing tools for calling between C/C++ and JS.

Show HN: How to compile C/C++ for WASM, pure Clang, no libs, no framework
Since I haven't seen it mentioned in the comments yet, here's another interesting project in the general area of "WASM without Emscripten":
https://github.com/schellingb/wajic
This provides an alternative implementation of Emscripten's EM_JS() magic (embed Javascript snippets right in the C/C++ source code), but without the Emscripten SDK. It still needs some additional tools next to Clang, so it sits somewhere between "pure Clang" and "full Emscripten SDK".

Writing bindings to `dos-like` for Rust: some lessons learned
Alas, although there is WebAssembly support in the original dos-like, it is still not supported in the bindings for Rust. It would require a Rust toolchain to integrate with WAjic, which I am pretty much unfamiliar with. If you have any idea on how to achieve this, I would love to know.

Extism Makes WebAssembly Easy
Indeed, webassembly is moving extremely slowly. I started a project years ago expecting https://github.com/WebAssembly/memory-control/blob/main/prop... and https://github.com/WebAssembly/memory64 to be fixed at some point. Neither are yet, and the project still suffers from it to this day.
I think wasm is still great without these fixes, but I have lost confidence in the idea that wasm will reach its full potential any time soon.

The Tug-of-War over Server-Side WebAssembly
Additionally, googlers are championing memory control https://github.com/WebAssembly/memory-control/blob/main/prop..., which provides memory protection.

How do Rust WebAssembly apps free unused memory?
But researching it a bit I found this issue, so it clearly seems to be a problem for a bunch of people out there. And apparently both V8 and Spidermonkey have already addressed this quite recently, see this issue.

WebAssembly and C++
FWIW there is a proposal in the works to add page-based protection, which will allow unmapping the 0 page, restoring the trap-on-null-deref behavior that is important for many languages with safety checks.
