Demo

Tools (40)

Each tool is a standalone Node.js script (node tools/<name>.mjs). JSON output. Exit 0 always. No build step.

Auditing

Tool	What it checks
seo-scanner	63 rules: 39 SEO (meta tags, canonicals, headings, OG tags, structured data, sitemap, cross-page duplicate/orphan detection), 20 GEO (AI bot access in robots.txt, snippet restrictions, llms.txt, structured data for AI extraction), 4 AEO (FAQPage/HowTo/speakable schema)
a11y-scanner	WCAG 2.2 A/AA static checks: missing alt text, unlabeled form controls, icon-only buttons, missing lang/title/main, heading order, positive tabindex, zoom disabled, duplicate ids, broken aria references. Zero false positives.
ship-gate	Blocking quality gate — scores all auditors (shared math with /ship), compares to .ultraship/ship-gate.json thresholds, hard-fails on leaked secrets / critical findings, exits 1 on fail. Generates a pre-push hook + GitHub Actions workflow.
secret-scanner	AWS keys, Stripe keys, JWT secrets, database URLs, private keys. Redacts values in output.
vibe-security-scanner	Vibe-Coding Security Sentinel — context secret-scanner misses: server-only secrets behind a NEXT_PUBLIC_/VITE_ prefix, a decoded Supabase service_role key exposed to the client, service_role in a "use client" file, Supabase tables with no RLS. Zero false positives.
eval-scanner	Locates every LLM call site (Anthropic, OpenAI, Gemini, Mistral, Cohere, Ollama, Vercel AI SDK, LangChain) by provider + model id, detects the test runner and whether an eval suite exists. Flags AI features shipping with no evals. Seeds /evals. Zero false positives.
code-profiler	N+1 queries, sync I/O in handlers, unbounded queries, missing indexes, memory leaks, sequential awaits, ReDoS risk
bundle-tracker	JS/CSS/image sizes in build output. Detects heavy deps (moment→dayjs, lodash→native). History for before/after. Monorepo-aware.
dep-doctor	Unused dependencies via import graph analysis (not just grep). Dead wrapper files. Outdated packages.
content-scorer	Flesch-Kincaid readability, keyword density, thin content detection, GEO heading analysis
lighthouse-runner	Lighthouse via headless Chrome. Core Web Vitals, render-blocking resources, diagnostics.

Validation

Tool	What it checks
health-check	HTTP status, response time, SSL certificate (issuer, expiry), 6 security header
