Sucuri SiteCheck alternative for apps built with AI
Sucuri SiteCheck is a free remote scanner built to find malware, blocklisting, defacements and outdated CMS software. PwnMyVibeCode is a free check for apps made with AI tools: it looks for missing security headers and weak cookies, and on your own site for leaked API keys, public .env and .git files and loose CORS, with a fix you can hand to your AI agent. On WordPress, or if you suspect malware, use SiteCheck. For a React, Next.js, Supabase or Firebase app, use PwnMyVibeCode. You can also run both.

Where Sucuri SiteCheck is better

- Its report says it also detects credit card skimming malware.
- Behind it sits a paid platform with server side scanning, a firewall and unlimited malware cleanups.
Where PwnMyVibeCode is better
- It searches your HTML and up to 12 of your own scripts for secret keys from Stripe, OpenAI, Anthropic, AWS, GitHub, Supabase and more.
- It checks whether /.env, /.env.local, /.git/config and similar files are served to anyone who asks.
- It flags CORS that lets other sites read your logged in users' data.
- It spots Supabase and Firebase config in your code and points you to check your database rules.
- Every finding links to a fix page with the change to make and a prompt for your AI agent.
What neither one can see
Both scan from outside, like a visitor. Sucuri says its remote scanner only has access to what's visible at the browser level and won't detect anything on the server side. The same goes here: neither one reads your server code, tests your login logic or checks your database rules from the inside.
Which one should you use?
- A WordPress or other CMS site, or a sudden redirect or spam on your pages: Sucuri SiteCheck.
- An app built with Lovable, Bolt, v0, Cursor or Claude Code on React, Next.js, Supabase or Firebase: PwnMyVibeCode.
- Not sure: run both. They look for different things and both are free.
