Free website security scanner

Paste your URL and get 100+ security checks (exposed keys, SQL injection, XSS, headers, SSL/TLS, backend config) in about 30 seconds. Nothing to install and no source code — just the address and a free account for the findings to land in.

Free account required to see the results

Security findings are what an attacker would want most, so the report lands in your dashboard rather than on a public page. Creating the account is free and takes a minute. The SEO and AEO scanners need no account at all.

How it works

Three steps. One pasted URL.

  1. 01

    Paste your URL

    No install, no source code. Enter any public URL, then a free account to open the report.

    100+ checks in ~30s

    Secrets, injection, headers, SSL/TLS and backend config run in parallel against your live site.

    Fix what matters first

    Findings ranked Critical to Low, each with evidence and a copy-paste AI fix on paid plans.

Frequently asked questions

Is this website security scanner really free?
Yes. The scan itself costs nothing and runs on any URL in about 30 seconds. It does need a free account, because the report is a list of the ways your site can be broken into and that is not something to print on a public page. Signing up takes a minute and no card is asked for; paid plans add copy-paste AI fix prompts, more scans, and continuous monitoring. The SEO and AEO scanners run with no account at all.
Do I need to sign up or install anything?
Nothing to install. CheckVibe runs entirely in the cloud against your live URL, with no agent, no browser extension and no source-code access, so all you provide is the address and a free account for the results to land in.
What does the scan check for?
Over 100 checks in parallel: exposed API keys in your JavaScript, SQL injection, cross-site scripting (XSS), missing security headers (CSP, HSTS), weak SSL/TLS, permissive CORS, and backend misconfigurations like world-readable Supabase or Firebase data. It also scores SEO and AEO (AI-search visibility) in the same pass.
How long does a website security scan take?
About 30 seconds. CheckVibe crawls your site and runs every check in parallel, then ranks the findings Critical to Low so you know what to fix first.
What kinds of sites can it scan?
Any publicly reachable URL: a production app, a staging build, or an AI-/vibe-coded prototype from Lovable, Bolt, v0, Cursor or Replit. CheckVibe scans the deployed site regardless of framework or how it was built.
Will it tell me how to fix what it finds?
Yes. Every finding includes reproducible evidence and a plain-English explanation, and paid plans turn each one into a copy-paste fix prompt for Claude, Cursor, and Windsurf so you can patch it without becoming a security expert.
