Our review
Pros	Explore constructions built from points, vectors, lines, and polygons Modify construction elements directly with the mouse Create loci and extend functionality with Python-written macros	Drag base elements to update dependent parts of a construction. Supports Euclidean, hyperbolic, and elliptic geometries. Includes automatic proving, loci, CindyLab simulations, and CindyScript.
Cons	Desktop application for Linux and macOS, not an online classroom service No proof practice or problem practice features No classroom tools	Its scope centers on construction and exploration rather than proof practice. Classroom and practice features are less extensive than some alternatives. Documentation references older updates, which may complicate onboarding.
