Beep.js is a JavaScript toolkit for building browser-based synthesizers using the WebAudio API, with a batteries-included approach that lets you create a playable instrument in one line of code. It also supports MIDI controller keyboards via the Web MIDI API.

Use cases

• build a browser-based synthesizer
• play music in the browser with WebAudio
• connect a MIDI keyboard to a web app
• create a software piano keyboard in JavaScript
• write and play musical scores in the browser
• teach music concepts interactively on the web

When to choose

• you want a quick, batteries-included way to build a synth in the browser
• you need Web MIDI input support for a web instrument
• you're prototyping audio experiments or music lessons in JavaScript

When to avoid

• you need a maintained library with recent updates and support
• you need advanced synthesis features beyond basic notes, voices, and scores
• you need non-browser (Node.js or mobile native) audio synthesis
