Frequently Asked Questions

Which languages are supported?

JavaScript, TypeScript, Python, Go, Java, C#, PHP, and Ruby. Each language generates idiomatic code using its standard regex library.

How are regex patterns handled?

The tool validates your pattern first, then generates language-specific code. Some languages require escaping or different syntax (e.g., raw strings in Python, backticks in Go).

What does the test result show?

If you provide a test string, the tool will show whether the pattern matches and list all found matches. This helps verify your regex before using it in production.

Is my data sent to a server?

No, all processing happens entirely in your browser. Your regex pattern and test strings never leave your device.
