## What it is
API Designer is a standalone or embeddable web editor for authoring RAML (RESTful API Modeling Language) specifications, written in JavaScript with AngularJS. It stores files in an in-browser HTML5 LocalStorage filesystem by default and can be customized with alternative persistence implementations.

## Use cases
- design RAML API specifications in a browser
- embed a RAML editor into my own web application
- run a local editor for writing RESTful API definitions
- share and prototype API designs with a team
- replace the default storage with a custom filesystem backend

## When to choose
- your team designs APIs using RAML
- you need an embeddable, browser-based API spec editor
- you want a quick local tool for authoring RAML without setup

## When to avoid
- you design APIs with OpenAPI/Swagger instead of RAML
- you need a fully maintained project with active development
- you require a desktop-native editor
