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.

Best implementation for standalone + browser executable?
Wow, thanks a lot! I hit a snag running cyclone's repl on a M1 Mac, but found the fix here: https://github.com/justinethier/cyclone/issues/464

How to Detect a Cycle in a Linked List
When developing Cyclone Scheme I discovered the latest R7RS Scheme language specification requires that several procedures handle circular lists.

Which Scheme for compiling C to use in WASM?
Cyclone Scheme transpiles to C and can run in the browser using WASM.

Tail Call Optimization by Base Jumping off the Stack
Over the years various solutions have been developed to meet this requirement such as trampolines, goto's, compiler optimizations, etc. One of the most unusual was proposed by Henry Baker in his paper CONS Should Not CONS Its Arguments, Part II: Cheney on the M.T.A. (PDF).

Oldest Scheme Implementations
And its successor, Cyclone, began in 2014, and is actively developed.

If you had to pick a Scheme to write a standalone application which would you choose?
Gambit, and consequently Gerbil, are not very mature and still need a bit more of a environment. Stklos could also be interesting, as well as Cyclone.

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! :)
