Local Regex Tool

A regex tester that lives in your Mac menu bar.

Wring helps developers test regular expressions without leaving their current workflow. Paste sample text, try a pattern, inspect matches, and copy the result back where you need it.

What it does

  • Test regex patterns against sample text locally.
  • Inspect matches and capture behavior while iterating.
  • Avoid context-switching to browser-based regex testers.
  • Keep logs, customer text, and internal examples on your Mac.

Why local matters

Regex patterns and test text stay in the app. Wring has no account system, no app analytics, and no app network client/server entitlement.

When to use it

  • Build validation patterns for forms, logs, and CLI tools.
  • Test extraction patterns before adding them to code.
  • Debug regular expressions from any IDE or terminal workflow.
