If you’ve ever worked with regex, you know the pain:

You write a pattern
It looks correct
But it doesn’t match what you expect

So you:

Tweak it
Run again
Repeat 10 times 😅

🧠 The Problem with Regex

Regex is powerful… but:

Hard to debug
Easy to break
Difficult to visualize

Even small mistakes can cause:

No matches
Wrong matches
Performance issues

That’s exactly what a regex tester helps you do.
