About the product

Unrust helps developers check and practise the coding skills they use without assistance. Its free 14-minute diagnostic covers JavaScript, TypeScript, or Python with AI and autocomplete switched off. Six areas test recall, debugging, spotting flaws, tracing, idiomatic code, and reviewing AI-generated code. A free account adds one adaptive daily practice set. Optional paid plans add unlimited practice, focused workouts, and trends. Unrust is a coding diagnostic and practice tool, not a code-generation assistant.

For product owners

Promote Unrust

Every listing gets one post to our X and Threads followers. It is seen once, then the traffic stops. Promotion keeps Unrust in front of people instead.

  • Back in the X and Threads rotation: Unrust gets posted again instead of once.
  • A promoted slot on the AppRater homepage, carrying a Promoted badge.
  • A direct link to Unrust from a DR45 site (Ahrefs Domain Rating), with no redirect in between.
  • A labelled spot in the weekly email to AppRater subscribers, one promoted app per issue.
  • Stays on the first screen however old the listing is, while new submissions push everything else down.
