Cuis Smalltalk

Cuis Smalltalk is a free implementation of the Smalltalk-80 language and environment, guided by explicit goals of being simple, powerful, portable, fast and efficient. Rather than chasing feature parity with larger dialects, it keeps the core system lean so the whole environment remains understandable and malleable.

The environment provides the classic Smalltalk toolset: class browsers, inspectors, workspaces and a transcript for feedback during development. It also includes auto-completion and halo-based inspection, and it supports vector graphics, SVG, TrueType fonts and Unicode, which makes it suitable for building modern graphical applications.

Cuis is aimed at programmers interested in live, object-oriented development, from students learning Smalltalk concepts to experienced developers who value a compact, hackable system. Educators and researchers exploring malleable software also form a natural audience.

New users should begin with the official documentation and getting-started material, then experiment in a workspace and class browser to understand the image-based workflow. Because the community is smaller than in mainstream dialects, checking available packages before committing to a large project is wise.

Overall, Cuis offers a clean, focused Smalltalk experience for those who prioritize simplicity and direct control over their development environment.
