SecSnapr

Instantly scan headers, CSP, cookies, and client-side risks in any web app.

SecSnapr gives you instant, explainable security insights for any webpage. Click “Scan” and get a clear breakdown of browser-level risks, including headers, cookies, client-side behavior, and third-party dependencies—without intrusive testing. Built for developers and SaaS builders who want fast answers without running full audits. What SecSnapr checks: • Security headers (CSP, HSTS, framing protections) • Cookies and session handling • Client-side script risks and unsafe patterns • Third-party script dependencies and supply chain exposure • API and browser-accessible endpoints How it works: • Runs only when you click “Scan” • No background monitoring or tracking • Results are scoped to the current tab • Analysis is fast and non-intrusive What makes it different: • Correlated risk insights, not just raw findings • Clear “why it matters” explanations • Actionable fixes with effort levels (quick wins to advanced) • OWASP-aligned risk categories Privacy-first: • No data leaves your browser • No tracking or data collection • No external requests No setup required.
