Regex Tester

🔍 Why Use a Private Regex Tester?

Regular expressions (Regex) are essential for data validation and parsing, but testing them often involves using sensitive data like server logs, user emails, or internal code. The Manic Inventor Regex Tester is designed with a "Local-First" architecture:

• No Data Uploads: Unlike other online regex tools, your test strings never touch a server. All processing happens in your browser's RAM.
• JavaScript Native: This tool uses the native RegExp engine, ensuring that what you test here works perfectly in your web applications.
• Instant Feedback: Experience zero-latency debugging as you refine your patterns.

Pro-Tip: Use the g flag to find every instance in your text. Without it, the engine stops after the very first match it finds.
