WebRTC (where RTC stands for Real-Time Communications) is a technology that enables audio/video streaming and data sharing between browser clients (peers). As a set of standards, WebRTC provides any browser with the ability to share application data and perform teleconferencing peer to peer, without the need to install plug-ins or third-party software.

WebRTC components are accessed with JavaScript APIs: the Network Stream API, which represents an audio or video data stream, the PeerConnection API, which allows two or more users to communicate browser-to-browser, and the DataChannel API that enables communication of other types of data for real-time gaming, text chat, file transfer, and so forth.

PeerJS simplifies WebRTC peer-to-peer data, video, and audio calls.

PeerJS wraps the browser's WebRTC implementation to provide a complete, configurable, and easy-to-use peer-to-peer connection API. Equipped with nothing but an ID, a peer can create a P2P data or media stream connection to a remote peer.

What is it?

ShareDrop is a free app that allows you to easily and securely share files directly between devices without having to upload them to any server first.
How to use it?
Sharing files between devices in local network*

To send a file to another device in the same local network, open this page (i.e. www.sharedrop.io) on both devices. Drag and drop a file directly on other person's avatar or click the avatar and select the file you want to send. The file transfer will start once the recipient accepts the file.
Sharing files between devices in different networks

To send a file to another device in a different network, click + button in the upper right corner of the page and follow futher instructions.
Signing in

Additionally, you can sign in using Persona to allow others to easily recognize you. This will show others your email address and also your Gravatar, if you have one.

We never store anything. Files only served fresh.

WebRTC is a free, open project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others. This page is maintained by the Google Chrome team.
