https://cadquery.readthedocs.io/en/latest/intro.html – good intro

https://github.com/CadQuery/cadquery – the main repo

https://github.com/CadQuery/CQ-editor – GUI editor, like OpenSCAD, one of the many ways to use CQ

https://github.com/Wren6991/CQCAD – Luke Wren (ASIC designer at RasPi)’s collection of CQCAD parts
Also simliar: OpenJSCAD but also cannot export STEP
And the original: OpenSCAD
