Built with Codex, Claude, or Cursor?

Scan the code before the public app.

The website scanner sees what reached production. The repository scanner checks a public GitHub repository for committed environment files, secret patterns, risky GitHub Actions, exposed client keys, weak Supabase signals, and unsafe build settings. Verified findings can be copied as technical fix prompts for your coding agent.

Read-only. No clone, package install, build, or code execution. Private repository connection is coming later.

.env and credentials

Flags committed environment files and high-confidence provider, database, and private-key patterns.

GitHub Actions

Reviews token permissions, pull_request_target usage, secret output, and mutable third-party actions.

Supabase boundaries

Looks for service-role exposure and migrations that create tables without visible RLS enablement.

Client and build risk

Checks public secret prefixes, wildcard CORS, raw HTML sinks, eval, and production source maps.

More than a pass or fail

A vulnerability report your team can actually use.

Most scanning tools produce a wall of warnings. ScanMySaaS keeps the affected URL, groups findings by priority, and gives paid users practical remediation for each issue.

How it works

How does a web vulnerability scanner work?

Start with a URL, let the automated scanner inspect the public surface, then use the report to decide what to verify and fix first.

STEP 01

Point us at your app

Enter a public URL you own or are authorized to test.

STEP 02

We inspect the surface

The crawler discovers pages and checks observable security signals.

STEP 03

Work down the risk

Open the report, address priority findings, then run a fresh scan.

Security coverage

What our website vulnerability scanner checks for.

ScanMySaaS runs 60+ automated checks across the exposed web application. It tests public signals only—it does not log in, exploit targets, or replace a human security review.

SSL & transport

SSL/TLS use, HTTPS redirects, HSTS, mixed content, and downgrade risks.

Security headers

CSP, framing protection, MIME sniffing, permissions policy, referrers, and more.

Exposed files

Public environment files, Git metadata, backups, logs, source maps, and debug paths.

Cookies & forms

Secure, HttpOnly, and SameSite flags plus observable CSRF protection gaps.

Client-side risk

Unsafe JavaScript patterns, detectable outdated libraries, and injection signals.

App exposure

Technology leakage, public API docs, open redirects, DNS signals, and CORS.

AI discovery

llms.txt availability and a readable public resource map for compatible AI tools.

Crawl readiness

robots.txt, XML sitemap, canonical URL, homepage indexability, and security.txt.

Your first scan is free

Know what your launch left exposed.

No credit card. Use it on a website you own, keep the report, and decide what deserves attention.

Vulnerability scanner FAQ

Before you scan your SaaS.

How do I scan a SaaS application for security vulnerabilities?

Enter a public URL you own or are authorized to test. ScanMySaaS crawls up to 25 reachable pages, runs more than 60 automated website vulnerability checks, and returns a prioritized report with severity, affected URLs, and finding descriptions.

How does a website vulnerability scanner work?

A website vulnerability scanner inspects the public surface of a web application for observable security issues and misconfigurations. ScanMySaaS checks transport security, response headers, cookies, forms, exposed files, client-side code, redirects, DNS and email-security signals, then groups the findings by severity.

What types of vulnerability does the scanner detect?

The scanner looks for SSL and HTTPS problems, missing or unsafe security headers, risky cookie settings, exposed environment or backup files, CORS mistakes, open redirects, source maps, outdated client-side libraries, unsafe JavaScript patterns, and other publicly observable web application risks.

Is ScanMySaaS a free website vulnerability scanner?

Yes. Your first scan is free, requires no credit card, and can inspect up to 25 reachable pages. The free report includes the security score, severity breakdown, affected URLs, and finding descriptions. Paid plans add detailed remediation guidance, monthly credits, rescans, saved history, and score trends.

How is ScanMySaaS different from Burp Suite or Nikto?

ScanMySaaS is designed as a quick, browser-based outside-in check for SaaS founders and product teams. It requires no installation or command line, but it is not a replacement for Burp Suite, Nikto, manual penetration testing, or a professional security review.

Do I need penetration testing experience to use it?

No. Findings are ordered by severity and connected to the page where each issue was observed. Paid reports add practical remediation steps and configuration examples, while every result should still be verified before making a production change.
