Wormhole is a browser-based tool that allows people to instantly share files with end-to-end encryption. The service uses WebTorrent under the hood and is free to use. BitTorrent will speed up transfers but people are not required to keep their browser windows open if files are smaller than five gigabytes.
Most people still associate torrents with desktop clients. However, the browser-native WebTorrent equivalent has become the driving force behind many innovative services.
Simply put, WebTorrent has built a bridge between BitTorrent with the web. Instead of using standalone applications, it allows people to share files directly from their browser, without having to configure or install anything.
In recent years there have been a few services built on this technology. βTorrent is a full-fledged torrent client that works in the browser, and File.pizza was one of the first to develop a simple one-click file-sharing tool.
The new “Wormhole” service also offers free and simple file-sharing, but it goes a step further. Wormhole adds a privacy layer by offering end-to-end encrypted file transfers. And while it uses WebTorrent under the hood, users don’t have to keep seeding.
