Documentation & FAQ

What Obfuscation Protects

  • Source code theft and copying
  • Reverse engineering of business logic
  • API keys and sensitive data extraction
  • Unauthorized code modification

What It Cannot Protect

  • Network traffic interception
  • Server-side vulnerabilities
  • Malicious code injection prevention
  • 100% against dedicated hackers

Best Practices

1

Use Source Maps for Development

Keep source maps separate for debugging while distributing obfuscated code

2

Test Performance Impact

Always test obfuscated code performance before production deployment

3

Combine with Other Security Measures

Use obfuscation alongside server-side validation and encryption
