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.

Oldest Scheme Implementations
STklos was indeed born in 2001, but it was the successor of Stk, which is much older. Its first release was in 1993. As far as I know, STkos did use code from STk, so I'm not sure one couldn't say it was born in 1993, as "STk".

Most readable Scheme implementation
That said, I'd just like to mention that I have made an effort to write internals documentation ( general: "hacking", bytecode: "vm") to STklos. It's an interesting implementation because it's easy to add primitives and change the compiler. The internals of the VM is actually a bit more complex... But it's really interesting code.
- STklos 1.70 was released

August 2021 - What are you up to schemers ?
I've been working on enhancing STklos' macro system. The idea is to implement `syntax-case` properly and use it to obtain a better implementation of `syntax-rules` (the one in STklos is quite old and has some issues).

STklos 1.60 released
SRFI 143 has already been accepted, and there are recent pull requests for 170, 215, 217! :)

Oldest Scheme Implementations
Since you're listing Gerbil which is from 2016, maybe also list Sagittarius, which dates back to at least 2011
What are some alternatives?
LIPS - Scheme based powerful lisp interpreter in JavaScript
cyclone - :cyclone: A brand-new compiler that allows practical application development using R7RS Scheme. We provide modern features and a stable system capable of generating fast native binaries.
ribbit - A small and portable Scheme implementation with AOT and incremental compilers that fits in 4K. It supports closures, tail calls, first-class continuations and a REPL.

CSCMIC - Learning to make a Scheme interpreter in C
STk - STk is the ancestor of STklos (https://stklos.net) This repository contains fixes to allow the compilation of 4.0.1 on modern versions of GCC
husk-scheme - A full implementation of the Scheme programming language for the Haskell Platform.
