## What it is
RecordRTC is a server-less, client-side JavaScript library for recording WebRTC audio, video, screen, and canvas media streams directly in the browser. It wraps the MediaRecorder API with cross-browser support for Chrome, Firefox, Opera, Edge, and Safari, and includes a companion Chrome extension for screen recording.

## Use cases
- record audio and video from webcam and microphone in the browser
- capture screen activity as a video recording from a web page
- record browser canvas animations including 2D and 3D WebGL content
- build a client-side screen recorder Chrome extension
- record WebRTC media streams to blobs for upload or download
- capture GIF recordings from a media stream in the browser

## When to choose
- you need purely client-side media recording with no server component
- you want cross-browser recording support beyond raw MediaRecorder quirks
- you need to record screen, camera, microphone, or canvas streams in a web app
- you want a lightweight library with promise-based and callback APIs

## When to avoid
- you need server-side or native desktop recording rather than in-browser capture
- you require guaranteed codec support across all browsers, since codec availability varies
- you need long-duration, high-reliability recording with advanced post-processing features
- you need active development and frequent updates, as the project is in maintenance mode
