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.
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.

14
vulnerability types with instant Quick Fix
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.
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.
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.
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.
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.
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.
Three steps from installation to secure code.
Open VSCode Marketplace (Ctrl+Shift+X), search for "VEXLIT", and click Install. The extension activates automatically for all supported file types.
As you type, VEXLIT's LSP server analyzes your code in real-time. Security issues appear as underlined warnings with severity icons. Hover for full details including CWE references and exploitation scenarios.
Click the lightbulb icon or press Ctrl+. to see Quick Fix suggestions. Select a fix and VEXLIT replaces the vulnerable code with a secure alternative - no copy-paste, no manual changes.
