Are developer tools safe for proprietary code and identifiers?

Yes! All formatting, parsing, and cryptographic operations execute strictly inside your local browser sandbox. No source code, tokens, or configuration strings are ever sent over network connections.

Does the JSON Formatter support both indentation formatting and minification?

Yes! You can toggle between 2-space or 4-space beautification for easy debugging, or compress the JSON payload into a single minified line for production deployment.

Which cryptographic hash algorithms are supported?

We support SHA-256, SHA-512, SHA-1, and MD5 using browser-native SubtleCrypto implementations for maximum cryptographic speed.

Can I test regular expressions against multiline input?

Yes, our Regex Tester supports global (g), case-insensitive (i), multiline (m), and dotAll (s) regex flags with real-time match highlighting.
