## What it is
Mergely is a JavaScript component for interactively diffing and merging text files in the browser, using an LCS-based diff algorithm with a customizable markup engine. It ships with a rich API and React/Angular wrappers for easy integration into existing web applications.

## Use cases
- compare two text files side by side in a browser
- embed a diff/merge viewer in a web application
- show code changes between two versions online
- merge conflicting document edits interactively
- diff xml, html, java, or javascript source in the browser

## When to choose
- you need client-side diff/merge without a server round-trip
- you want a React component for comparing text in your app
- you need a customizable diff UI with an API for scrolling and setting contents

## When to avoid
- you need syntax highlighting out of the box for many languages
- you need command-line or server-side diffing rather than a browser UI
- you require an actively maintained Angular integration

## Facets
- artifact type: library
- maturity: active
- function: ui-components, parser, developer-tools
- domain: developer-tools, web-development, text-editors
- platform: browser
