NullToHero is an add-on for Claude that lets you design, SEO-optimize, inspect, and audit websites using natural language. Claude handles the technical work while you stay in control.
NullToHero is a comprehensive Claude Code plugin that provides four integrated skills: Siteasy (design system and page builder), SEO (AI search and ranking optimization), Inspect (WCAG accessibility and code quality checks), and Audit (whole-site orchestrator that runs 15 parallel sub-agents with deterministic 0-100 scoring). It includes over 60 commands and 110 reference docs, making it easy to build and ship high-quality websites even without coding experience.
Strong trust signals; still review the README and permissions before production use.
