DevHelper provides detailed validation with specific error messages for invalid URLs. It identifies issues like malformed schemes, invalid characters, or incorrect URL structure with suggestions for fixes.

Can it handle international domain names?

Yes! DevHelper fully supports internationalized domain names (IDN) with automatic punycode conversion and Unicode character handling for global web applications.

What query parameter formats are supported?

All standard query parameter formats including multiple values for the same key, encoded values, array notation, and complex nested parameter structures used in modern web frameworks.

Can I build URLs from individual components?

Yes, DevHelper includes URL construction features where you can input individual components (scheme, host, path, parameters) and automatically build properly formatted URLs.

How accurate is the URL validation?

DevHelper uses comprehensive URL validation following RFC standards, checking scheme validity, domain name format, port ranges, and overall URL structure for maximum accuracy.
