Glob Pattern Tester
Check which paths match a simple glob pattern.
Test glob patterns
Glob patterns like src/**/*.js drive build tools, linters, and CI config, but it is easy to write one that matches too much or too little. This tester checks which of your sample paths a glob matches, so you can confirm the pattern before relying on it.
Verifying against real paths catches the classic mistakes — a missing double-star, an over-broad wildcard — before they silently skip or include the wrong files. Enter a pattern and some paths and see exactly what matches.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
