## What it is
Regex Vis is a web application for visualizing regular expressions as diagrams and editing them visually. It also supports testing regular expressions against sample text.

## Use cases
- visualize a regex as a diagram
- edit regular expressions visually
- test regex patterns against text
- understand a complex regular expression
- debug why a regex doesn't match
- learn regular expression syntax

## When to choose
- you need to understand or explain a complicated regex
- you want to build or modify regex patterns without memorizing syntax
- you want a free, open-source, browser-based regex tool

## When to avoid
- you need regex search across large files or codebases
- you need programmatic regex processing in your own code
- you need offline or CLI-based regex tooling

## Facets
- artifact type: application
- maturity: active
- function: developer-tools, editor, parser
- domain: developer-tools, web-development, text-editors
- platform: browser
- tags: regex, visualizer, regex-editor, regex-testing, web, typescript, react
