TL;DR
VS Code relies on extensions for security features, which introduces its own risks. WebStorm includes built-in code inspections and security analysis. VS Code's extension marketplace has had malicious extensions; WebStorm's curated plugins are safer. For security-focused development, WebStorm's built-in features are more trustworthy; VS Code requires careful extension vetting.
VS Code and WebStorm are popular choices for JavaScript/TypeScript development. While both can be configured for secure development, they differ in how security features are delivered. Understanding these differences helps you choose and configure your IDE securely for vibe-coded applications.
Security Feature Comparison
| Security Feature | VS Code | WebStorm |
|---|---|---|
| Built-in Code Analysis | Basic | Comprehensive |
| Security Inspections | Via extensions | Built-in |
| Extension/Plugin Security | Open marketplace | JetBrains verified |
| Workspace Trust | Yes | Yes |
| Telemetry Control | Configurable | Configurable |
| Secret Detection | Via extensions | Built-in |
| Dependency Scanning | Via extensions | Built-in |
Extension Security Risk
VS Code extensions run with full access to your file system and can execute arbitrary code. Malicious extensions have been found in the marketplace. Carefully vet extensions before installing and limit installations to necessary, well-maintained extensions from trusted publishers.
Code Analysis
VS Code Analysis
VS Code provides basic syntax highlighting and IntelliSense. Advanced analysis requires extensions like ESLint, TypeScript language features, or security-focused extensions. This modular approach is flexible but requires configuration and trusting multiple extension authors.
WebStorm Analysis
WebStorm includes comprehensive code analysis out of the box: type checking, code inspections, security checks, and dead code detection. The analysis is deep and context-aware because it's built into the IDE. No extension configuration required for core security features.
Extension/Plugin Security
VS Code Marketplace
The VS Code marketplace is open, with minimal vetting. Extensions are scanned for known malware but sophisticated attacks can slip through. Popular extensions are generally safe, but lesser-known extensions pose risks. Extensions can be trojanized if maintainer accounts are compromised.
JetBrains Plugin Repository
JetBrains reviews plugins more thoroughly, though it's not immune to issues. The smaller ecosystem means fewer plugins but generally higher quality. JetBrains-developed plugins are trustworthy. Third-party plugins should still be vetted, but the risk is lower than VS Code's open marketplace.
Choose VS Code When: You want a free, lightweight editor and are willing to carefully manage extensions. VS Code is excellent when configured properly with vetted extensions. Best for developers who want control over their tooling and don't mind the configuration overhead.
Choose WebStorm When: You want security features built-in without extension management. WebStorm's comprehensive analysis and safer plugin ecosystem reduce configuration risk. Best for teams wanting consistent security tooling and enterprises with security requirements.
Workspace Trust
VS Code Workspace Trust
VS Code's Workspace Trust feature restricts what code can execute in untrusted workspaces. When opening unknown projects, VS Code asks whether to trust the folder. In restricted mode, tasks, debugging, and some extensions are disabled. This protects against malicious repositories.
WebStorm Safe Mode
WebStorm has similar protections for untrusted projects. It warns before running scripts or build tools in new projects. JetBrains IDEs also sandbox some operations to limit damage from malicious project configurations.
Best Practices
- Enable Workspace Trust / Safe Mode for untrusted projects
- Audit installed extensions regularly
- Disable telemetry if data sensitivity is a concern
- Keep your IDE and extensions updated
- Review extension permissions before installing
- Prefer well-maintained extensions with many users
- Configure security-focused linting and analysis
Are VS Code extensions safe?
Most popular extensions are safe, but the open marketplace has had malicious extensions. Vet extensions carefully, check publisher reputation, user count, and recent activity. Avoid installing unnecessary extensions.
Does WebStorm detect security issues?
Yes, WebStorm includes built-in inspections for common security issues in JavaScript/TypeScript code. It detects potential XSS, injection vulnerabilities, and insecure practices. The analysis is comprehensive without needing additional plugins.
What about Cursor, Windsurf, and AI IDEs?
AI-powered IDEs like Cursor (VS Code fork) inherit VS Code's security model plus AI-specific concerns. Consider where your code is sent for AI processing. These tools may send code to external APIs, raising data privacy considerations.
