Sitecheck.

Know what ships. A website auditor with a transparent score and evidence for every finding.

A clearer picture of a website.

Sitecheck scans a public URL for SEO, accessibility, technical health and content structure. Its TypeScript audit engine is independent of the command-line interface and Next.js dashboard, so the same rules power both.

What it checks

Titles and descriptions, social metadata, headings, image alt text, forms, links, document landmarks, structured data, insecure resources and common website mistakes.

What you get

A 0–100 score across four categories, plus severity, explanation, recommendation and evidence for every rule. Read the terminal report or export JSON.

How it is built

TypeScript, Node.js, Playwright, Zod and Next.js. Fixture-based Vitest tests, strict typing and GitHub Actions checks support the MIT-licensed v1.0.0 release.
