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.
