VSCode Extension

Security Scanning At the Speed of Typing.

Find vulnerabilities the moment you write them. VEXLIT's VSCode extension provides real-time inline detection, hover explanations, and one-click AI fixes - all without leaving your editor.

Security feedback comes too late in your workflow

Most teams discover vulnerabilities after code is merged - in CI pipelines, security audits, or worse, in production. By then, the fix is expensive and disruptive. VEXLIT shifts security left to the moment you type.

Key Features

Real-Time Inline Detection

Security issues are underlined as you type with 300ms debounced auto-scanning. No manual trigger needed - vulnerabilities appear instantly. Red underlines for critical issues, yellow for warnings, and blue for informational findings.

Hover for Full Context

Mouse over any highlighted issue to see the full explanation, CWE reference, severity level, confidence score, and suggested remediation. Each hover tooltip includes the OWASP Top 10 category and a link to the relevant CWE documentation.

One-Click Quick Fix

Press Ctrl+. (or Cmd+. on Mac) on any vulnerability for instant fix suggestions. 14 vulnerability types have pre-built Quick Fixes that replace insecure code with secure alternatives - parameterized queries, DOMPurify sanitization, environment variables, and more.

Zero Configuration

Install from the Marketplace and scanning starts immediately. No config files, no API keys, no sign-up required. VEXLIT automatically detects the language and applies the correct rules. Works with any project structure.

34 Languages Supported

JavaScript, TypeScript, Python, Java, Go, C#, PHP, Ruby, Rust, Kotlin, Swift, Scala, and 22 more - plus Infrastructure as Code files (Terraform, Dockerfile, Kubernetes YAML). Every language gets the same detection quality.

Problems Panel Integration

All findings appear in VSCode's Problems panel. Filter by severity, sort by file, and Ctrl+Click to jump directly to the vulnerable line. Findings update in real-time as you fix issues.
