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.

Ngn/k (free K implementation)
The author of Kona has written kerf which I believe is intended for this same space. I’ve never used it though. https://github.com/kevinlawler/kerf1

Ngn/k (free K implementation)
I can offer you the contrary opinion: why I would not use these kind of languages.
A couple of years ago I worked on a non-trivial APL application with one of my university professors and another student. We were trying to build a CPU simulator flexible enough to handle stuff ranging from PDP-11 up to Intel x86. The goal was to run some analysis on memory accesses performed by the x86 architecture. Quite an interesting project in which I worked on for around two year.
The code is still available if you're interested: https://github.com/emlautarom1/PDP_11_Simulator
The first implementation was done in APL using a book which I don't remember as reference. We had a couple of meetings where we learned APL and the general idea behind the design. Pretty soon we started to deal with a lot of issues like:
- We only found two implementations for the APL interpreter: GNU and Dyalog. GNU is free but pretty much abandoned. Support for Windows was (is?) nonexistent. Dyalogs version is proprietary so we couldn't use that (even when a "student" version was available).
What are some alternatives?
Kbd - Alternative unified APL keyboard layouts (AltGr, Backtick, Compositions)
kona - Open-source implementation of the K programming language
array - Simple array language written in kotlin
kdb - kdb+ Working Group from FINOS Data Technologies program
april - The APL programming language (a subset thereof) compiling to Common Lisp.
bqn-libs - Informal collection of BQN utilities
kerf - Kerf (Kerf2) is a columnar tick database and time-series language for Linux/OSX/BSD/iOS/Android. It is written in C++ and natively speaks JSON and SQL. Kerf can be used for trading platforms, feedhandlers, low-latency networking, high-volume analysis of realtime and historical data, logfile processing, and more.
