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.

Gimp 2.99.18 Released: The Last Development Preview Before 3.0
OCCT is definitely difficult.
I am almost as far as you can get from an expert but:
For example the TNP issue derives from OCCT (or something in the stack close to it, I am not exactly sure) not really handling face naming at all.
So if you want to avoid topological naming issues (which is a hard problem in CAD), you apparently have to do some work to track before and after and reconstruct your face naming.
https://wiki.freecad.org/Topological_naming_problem
https://forum.freecad.org/viewtopic.php?t=27278
Then there are various fairly entrenched issues to do with filleting and chamfering. Basically, both these operations will fail (in FreeCAD at least, but it's OCCT at "fault") if a chamfer or fillet would completely consume an existing edge. (It also sometimes creates impossible objects when filleting, or used to).
Booleans can be slow.
And more generally, it seems if you track the FreeCAD project that OCCT can be inscrutable when things fail; error messages aren't the greatest etc.
The flip side of OpenCascade is that it seems to be highly portable and has for example been compiled to JS with Emscripten for this astonishing thing:
https://zalo.github.io/CascadeStudio/
It's a monumental open source project, for sure, and it's definitely not nothing that we have an open source CAD kernel; these are projects that perhaps have to extend beyond the working life of an individual developer if they are to be stable. And there are loads of projects built around it.

Show HN: Dslcad a programming language and interpreter for building 3D models
If you haven't seen it you may want to check out https://github.com/zalo/CascadeStudio
From what I see, it is exposing the OpenCascade base commands directly, versus your completely new DSL, but you might be interested in a way to implement your DSL on top of such an interface such as this which takes out a lot of the extra work of having a rendering interface, exports, etc, maybe.

Ask HN: If money was no object what software would you create?
It's nowhere near ready for primetime, but you should take a look at CascadeStudio (https://github.com/zalo/CascadeStudio)

Fornjot – The world needs another CAD program
FreeCAD is GUI-based though, not code-first like Fornjot. A better comparison would be CadQuery (https://cadquery.readthedocs.io/en/latest/intro.html) or Cascade Studio (https://zalo.github.io/CascadeStudio/), both of which are code-first and based on the same CAD kernel as FreeCAD.

Support for Javascript?
It is an actual example from CascadeStudio, but I haven't looked into it enough to know how what actually happens under the hood, but I assume the following:

Procedural CAD Modelling tools for WebGL
then there are 2 others, sop/CSGboolean and sop/CADboolean. CSGBoolean is indeed based on CSG, and uses jscad. And the CAD one (which I show in the video in this post) is based on opencascade, which is the most powerful/stable. Then the output of both of those nodes is converted to threejs in order to be displayed in webgl.

Is there a way to share a network drive or a folder over the internet?
That being said, https://github.com/jscad/OpenJSCAD.org sounds like a winner for your requirement of NOT having to download a file across the internet.

Show HN: Replicad, the Library for CAD in the Browser
this looks very nice. i think i like the ergonomics of your library... the "sketch on a plane then extrude" workflow feels nice and familiar.
could you compare and contrast replicad to JSCAD (https://openjscad.xyz)?
the examples in your docs are quite sluggish to load in Safari, but the workbench is very snappy!

10 ways to get the best out of OpenSCAD
No one has mentioned OpenJSCAD, which is the same idea in Javascript: http://openjscad.azurewebsites.net/
https://github.com/jscad/OpenJSCAD.org/tree/V2
A fairly substantial rewrite is underway, the V2 branch linked above.

Code CAD – Use code to create CAD models
- Browserify to bundle the design into a website. Directly from the source CAD files, without rendering to a huge mesh file format.
It's cool because you get access to the whole javascript ecosystem, and it's native to the browser.
