Regex Tester

Frequently asked

Does Regex Tester preserve Unicode and emoji?

Yes. Regex Tester uses native JavaScript string handling, so multibyte characters, emoji, CJK scripts and right-to-left text are processed correctly.

Can my company use Regex Tester without breaking a compliance rule?

In most cases, yes. Because nothing leaves your device, Regex Tester sidesteps the typical "cloud tool" data handling concerns. Check your internal policy if in doubt.

Is there a hidden pro version of Regex Tester?

There is not. Every feature of Regex Tester is available to everyone on the first visit, and nothing is gated behind a subscription.

Can Regex Tester be used from the keyboard only?

Yes. Press Ctrl+Enter (or Cmd+Enter on macOS) to run, use the slash key to open search, and Tab to move between inputs.
