Unrust

Unrust is a coding diagnostic and practice platform for JavaScript, TypeScript, and Python. Its diagnostic work is completed without AI or autocomplete, helping developers exercise recall, debugging, code tracing, language idioms, and the ability to find flaws. Learners can also review AI-generated code and practice evaluating it. Unrust focuses on building and checking programming skills through direct work with code; it is not an AI coding agent or code generator. Free diagnostic and account features are available, with optional paid practice. Developers can use the assessment to identify skill gaps and choose areas for further practice.
