buggy.run

buggy.run is an automated web application security auditing tool designed for developers, startups, and small teams. It finds data leaks and vulnerabilities in web apps by performing deep, real-browser-based scans that reach both public and authenticated pages. The core problem it solves is the difficulty and cost of performing regular security audits — buggy.run makes security testing accessible, affordable, and actionable for non-security experts.

What Makes buggy.run Stand Out

• Real-browser crawling: Unlike traditional scanners that only check public pages, buggy.run uses an AI-powered crawler to navigate behind logins and map out every page of your app, including those that contain sensitive functionality.
• 56+ security checks per page: Every crawled page is tested for HTTP security headers, TLS configuration, cookie security, information disclosure, injection flaws, and more — far beyond what basic scanners cover.
• AI-driven data leak detection: Every network response is inspected by an AI model for session tokens, PII, API keys, and secrets that may be accidentally exposed in response bodies or headers.
• Plain-English triage and fixes: Findings are ranked by severity and explained in simple language with the exact request that triggered the issue and a recommended fix. Users can ask the AI agent follow-up questions to clarify or get additional guidance.
• Safe, capped testing: Load and rate-limit tests are designed to identify missing rate limits or lockouts without risking application stability or downtime.

Who Should Use buggy.run

• Solo founders and indie developers who need to ship secure products but lack a dedicated security team — buggy.run provides an accessible, automated audit that fits into a lean workflow.
• Small engineering teams that want to integrate security testing into their CI/CD pipeline without hiring a security consultant — the tool supports both on-demand and continuous auditing.
• Agencies building client websites who need to demonstrate security compliance and catch vulnerabilities before deployment — the Expert plan covers multiple projects and provides live support.

Frequently Asked Questions

What is buggy.run?

buggy.run is an automated web application security auditing service that scans both public and authenticated pages to find data leaks, misconfigurations, and vulnerabilities. It provides actionable, plain-English reports with recommended fixes.

How does buggy.run work?

After you provide your website URL and optional test credentials, buggy.run runs a six-phase engine: it crawls public and in-app pages, captures all network traffic, runs 56+ security checks per page, analyzes responses for data leaks, fuzzes inputs with safe payloads, and performs capped load tests. Results are triaged by an AI agent with severity rankings and fix instructions.

What platforms and stacks does buggy.run support?

buggy.run works with any web application that serves HTTP, regardless of framework or stack — React, Angular, Vue, Node, Next.js, Ruby on Rails, Django, and more. No SDK or code changes are required.
