Greadme — website audits for SEO, performance and AI visibility, built with Next.js on Vercel - Showcase

Hi all. I built Greadme, a website audit tool, and it runs on Vercel, so posting it here.

What it does: you enter a URL and get a scored report. Page Audit runs 190+ checks across performance, SEO, accessibility, best practices, security and structured data. Site Audit crawls up to 500 pages and lists issues per page. There's also a Content Audit for writing quality, an AI Visibility Checker that asks ChatGPT, Claude and Gemini real questions and reports whether your domain gets mentioned, and Scheduled Audits that re-run any of these and email the report. Every finding comes with a copy-ready fix prompt for your AI coding assistant.

Two tools are free with no signup, if you just want to try something:

Schema Validator: https://www.greadme.com/schema-validator

Greadme

JSON-LD Validator: How to Validate Structured Data Free | Greadme

Free JSON-LD validator: scan a URL or paste structured data, get parse errors, schema.org checks and Google's required properties per type, with a fix for each. No signup.

AI Access Checker (can AI crawlers actually read your site: robots.txt, llms.txt, noindex, client-side-only rendering): https://www.greadme.com/ai-access-checker

Stack: Next.js, React, TypeScript, MongoDB, Vercel, Clerk (auth), Upstash, Resend (email), Anthropic + OpenAI + Google Gemini APIs.

Pricing: free plan (5 Page Audits, 3 Site Audits a month); paid from $29/month with a free trial.

Happy to answer questions about running crawls and long audits on Vercel. Feedback welcome, especially on checks you'd want that aren't there.
