Meet Unrust
Unrust is for developers who want to measure their own unassisted coding after leaning on AI assistants. A free 14-minute diagnostic with no AI, autocomplete or search returns a six-part profile covering recall, debugging, finding flaws, tracing, idiomatic code and AI-slop detection. A subscription adds saved retakes, a drill library and adaptive practice.
A practical workflow
- Take the free diagnostic in one quiet sitting
- Read the profile and pick your weakest area
- Practise that area with short drills
- Retake the diagnostic later to compare
Illustrative input
This example describes a task, not a tested output. Adjust the source material and settings to your own situation.
Take the diagnostic in Python and note whether recall or code tracing is the weaker area.
Result check: Treat one result as a snapshot, since the site says it cannot separate skill from time pressure or a bad day, and compare against a second attempt.
Access and alternatives
The first diagnostic is free and needs no account. Subscribers get saved retakes, practice without a daily limit, the drill library and per-skill mastery tracking. The page reviewed did not state subscription prices or the free practice limit, so check the site before subscribing.
Choose another workflow when its emphasis fits better: Khanmigo for AI tutoring help instead of unassisted drills.
