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.

Nim v2.0 Released
It should probably be redone with mummy (multi-threaded) and chronos (async single-threaded):
Ones that have not been mentioned so far:
nlvm is an unofficial LLVM backend: https://github.com/arnetheduck/nlvm
npeg lets you write PEGs inline in almost normal PEG notation: https://github.com/zevv/npeg
futhark provides for much more automatic C interop: https://github.com/PMunch/futhark
nimpy allows calling Python code from Nim and vice versa: https://github.com/yglukhov/nimpy
questionable provides a lot of syntax sugar surrounding Option/Result types: https://github.com/codex-storage/questionable
ratel is a framework for embedded programming: https://github.com/PMunch/ratel
cps allows arbitrary procedure rewriting to continuation passing style: https://github.com/nim-works/cps
chronos is an alternative async/await backend: https://github.com/status-im/nim-chronos
zero-functional fixes some inefficiencies when chaining list operations: https://github.com/zero-functional/zero-functional
owlkettle is a declarative macro-oriented library for GTK: https://github.com/can-lehmann/owlkettle
A longer list can be found at https://github.com/ringabout/awesome-nim.

Nitter (Twitter front end) is working again
The frontend uses Karax, which is my favorite frontend/SPA library. It is an absolute joy to use, even if it's a bit rough around the edges.

I learned 7 programming languages so you don't have to
I have used Nim for personal projects for 6 years now and it continues to surprise me on how well versed it is for many problem domains. I am fond of it's SPA framework, karax https://github.com/karaxnim/karax for which I wrote a translation utility https://github.com/nim-lang-cn/html2karax Latest Nimv2 release candidate has improved in the ergonomics and syntax that affect compilation to js, so I was able to cleanup my webapp's code to be less verbose. On GPU programming there has been a few projects that touch GPU programming, most notably https://github.com/treeform/shady

Web apps in pure Python.
And it's present not only in Python but in other languages as well. Check for example https://github.com/karaxnim/karax - I don't know why people would want to hide all of their HTML in Python/whatever language. Then limit their ability to script and style it in one way or another.

A Cost Model for Nim
> the real killer feature to me is the javascript target
Agree, this is amazing because you can share code and data structures between front and backend (for example: https://github.com/karaxnim/karax).
Also, it's really nice having high level stuff like metaprogramming and static typing spanning both targets. Things like reading a spec file and generating statically checked APIs for server/client is straightforward, which opens up a lot of possibilities.

Will Zig interop with JavaScript/Web at all?
E.g. Nim focuses on enabling what it calls "single page web apps": https://github.com/karaxnim/karax.

How to use JS to make a front end
I recommend you to take a look at Karax. It's a front-end framework for Nim that can compile to regular JavaScript. If you want to know how to use it with a webserver, Joker is a good example. With the Joker config, all of the compiled .js files land in /public/views, where you can take a look at them. But keep in mind that the JS that Nim produces is often rather cumbersome and hundreds of lines long, even if it's just a simple program.

Building a simple room-based chat application in Nim (using HTMX)
`buildHtml` is a macro, the code passed to it via it's invocation (the 'colon-delimited indented code blocks') is then transformed as explained in the readme https://github.com/karaxnim/karax#hello-world and compiled. Macros are explained in the manual https://nim-lang.github.io/Nim/manual.html#macros
The `text` function in the Karax DSL is actually escaped once it is converted to a string, see https://github.com/karaxnim/karax/blob/c71bc927494418c3f52f9... for the implementation if you are curious. There is a way to render raw HTML using `verbatim` instead of `text` in Karax.
So in this case, I believe it would be protected against XSS to some extent, but I obviously haven't done an in depth security check for a demo/simple project. There are plenty of other potential issues as well (username collisions, websocket errors, user lists) but I judged those to be out of the scope of a simple project like this.

Nim Version 1.6 Released
Well no language is perfect, but Nim can be used in almost every domain because of it's compilation targets(C, C++, JS) and it's fast compile times(who needs interpretation when compile times are that fast!):
* Shell scripting, I still assume most people will just use Bash tho: https://github.com/Vindaar/shell
* Frontend: https://github.com/karaxnim/karax or you could bind to an existing JS library.
* Backend: For something Flask-like: https://github.com/dom96/jester or something with more defaults https://github.com/planety/prologue
* Scientific computing: the wonderful SciNim https://github.com/SciNim
* Blockchain: Status has some of the biggest Nim codebases currently in production https://github.com/status-im?q=&type=&language=nim&sort=
* Gamedev: Also used in production: https://github.com/pragmagic/godot-nim and due to easy C and C++ interop, you get access to a lot of gamedev libraries!
* Embedded: this is a domain I know very little about but for example https://github.com/elcritch/nesper or https://github.com/PMunch/badger for fun Nim+embedded stuff!
Most of the disadvantages come from tooling and lack of $$$ support.

What are some simple but powerful compile-to-JS languages I might not know about, or that you are working on (not Elm, Reason, PureScript, or ClojureScript)?
I really like using Nim. It features a Python-like syntax and you can compile code to C, C++, ObjectiveC and JavaScript. If it doesn't support a certain JS feature, you can add it yourself. Due to Nim's amazing metaprogramming, you can even use it as a replacement for HTML within Karax.
