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.

Ravi is a dialect of Lua, with JIT and AOT compilers
it's based off MIR, does it have something to do with https://mlir.llvm.org/ ?
for typed lua, there is another effort https://github.com/teal-language/tl in addition to the mentioned typescript approach: https://github.com/andremm/typedlua

Lua Criticism Is Unwarranted
I had the pleasure of working with Lua 5.1 back in the late noughties. For me it's replaced Tcl whenever I want something I can configure above a C library. At the time I used it I found it quite nice but I'll also not forget the hours I wasted tracking down nil table corruptions which could have easily been caught by a type checker.
I had some hope that Luau https://luau-lang.org or Teal https://github.com/teal-language/tl would make things better but with the following example
function foo(x: number): string
- Why Fennel?

What's the deal with Fennel in Neovim?
There is already https://github.com/teal-language/tl, which is typed Lua. I think fennel exists to serve a different niche-- personally I use it not for any type features; I just like the syntax better, and others may find certain features like the macro system useful.

Using other languages
There's also some languages made to compile straight to Lua: - MoonScript is the most popular Lua wrapper - it's built to be more Python-like, featuring indentation-based scopes, function calls without parentheses, lambda syntax, list comprehension, and much more. - Yuescript is a modern update to MoonScript that adds more features (I haven't used it myself, so I'm not entirely sure exactly how it differs from MS). - Teal is a version of Lua that adds static typing for better code standards.

Bog – small, strongly typed, embeddable language
Terra and Nelua are both very different in goals than Teal. Teal is literally gradual types integrated into Lua keeping as many of Lua's idioms as possible (to a fault[1]). Terra and Nelua are both very metaprogrammable systems programming languages. Nelua's goals are primarily to soften C's rough edges, comparable to something like Nim.
There's another one you missed in Pallene[2]. But again, it's goal was to optimize the stack sharing involved in using the C API. It also adds types though and maintains Lua idioms as much as possible.

Lua: The Little Language That Could
lua on its own right can be fun too! If you are looking for a project to contribute to, there's for instance the Prosody XMPP server that's written in it, and contributes to the betterment of internet by promoting federated protocols.
There's also the http://prosody.im/ XMPP server that's written in Lua, and it's very successful there. The other major XMPP server implementation is in Erlang and they are equally praised, so that should tell something about Lua's versatility.

A History of Lua
You can write largish standalone application in Lua and it is not always a poor choice - Prosody [1] first comes to mind. But qualities which make it a good embedded language make it less _attractive_ for other uses.
Lua has very simple syntax and small stdlib which allows its implementation to be very small - you can add Lua to your application and not increase its size significantly. But when the size is not a concern most programmers prefer languages with rich, powerful syntax lots of features and batteries-included stdlib (which is completely opposite of Lua).

Chat app to allow messaging between my daughter and I?
If you are really set on a LAN-only setup you could look at Prosody (combined with an Android app such as Conversations) which Snikket is based upon. It's not as "ready to go, out of the box" as Snikket and therefore requires a slightly higher skill level, but in exchange it is a lot more customizable and adaptable to different kinds of deployment scenarios.

Ask HN: What is your recommended stack for real time chat?
My choice, because it's the stack I know very well, would be Prosody ( https://prosody.im/ - I'm one of the devs) and a web client such as Converse.js ( https://conversejs.org/ ). XMPP is highly extensible, Prosody is highly modular, which make them a good foundation for building on top of.
That said, the right stack is generally the one that matches your requirements, and (if this isn't primarily a learning exercise) whatever you're most familiar with. The hardest part of building a Discord or Slack-like in 2022 is actually not the technical stuff. There are many comprehensive open-source products already out there that compete with these companies, such as Mattermost, RocketChat and Element.
