LaunchLint is a security preflight tool designed to evaluate web applications and AI-built apps by scanning the public surface for vulnerabilities such as exposed credentials, risky default settings, and missing browser defenses before deployment, thereby preventing common security misconfigurations. Its key features include deterministic and non-invasive checks that analyze the submitted webpage and a limited set of scripts without executing code or probing endpoints, providing masked evidence, clear remediation instructions, and verification-friendly fixes; it also evaluates security headers, cookie flags, secrets, source maps, and secure transport mechanisms to ensure solid application security. This tool addresses the needs of developers, security professionals, and DevOps teams by identifying security weaknesses early in the development lifecycle, ensuring compliance with best practices, and safeguarding sensitive information for any web.

LaunchLint can be found in Application Security Testing (SAST/DAST) categories.

LaunchLint Main Features

• Source maps
  It looks for source map references in production JavaScript that could reveal source code.
• Cookie flags
  It verifies if cookies have secure, HttpOnly, and SameSite flags to keep them safe.
• Public secrets
  It finds production credentials or secrets that are visible publicly and masks them.
• Security headers
  It checks if security headers like CSP, frame protections, and MIME policies are set properly.
• Stack-aware fixes
  It provides specific fixes for common frameworks and hosting platforms when issues are found.
• Privacy in scanning
  It only reads the submitted page and does not attempt to find exploits or attack the app.
• Public surface scan
  It checks the app before you launch to find risky defaults, exposed credentials, and missing browser security defenses.
• Deterministic checks
  It uses clear rules to check the app without using models or trying to exploit anything.
• Scan of submitted page
  It only looks at the page you submit and up to five same-origin scripts, without executing JavaScript or trying to attack.
• Evidence and remediation
  Each finding shows what changed, with masked evidence and clear steps to fix issues.
• Non-invasive and transparent
  The scan is safe, only checks what is publicly available, and does not attempt to exploit vulnerabilities.
• Mixed content and secure transport
  It checks for mixed content issues and whether HTTPS and HSTS are used to keep data secure.
