Which glob features are supported?

It supports * (any characters except a slash), ** (globstar — across directories), ? (a single character), character classes like [a-z] and [!abc], and brace alternation like {ts,tsx}.

How is the matching done?

Each pattern is compiled to a regular expression in your browser and anchored to the whole path, so a path matches only when the entire string fits the glob. Brace alternation is expanded before compilation.

Are my paths uploaded anywhere?

No — the pattern compilation and matching run entirely in your browser with JavaScript. Nothing is sent to a server.

Glob Pattern Tester — Gera Tools

Test glob patterns against your paths

Paste a glob pattern and a list of file paths and see exactly which ones match — instantly, as you type. Useful for sanity-checking gitignore rules, build globs, CI path filters, and tooling config before you commit them.
