Instant.io is a web application for streaming file transfer over WebTorrent (BitTorrent over WebRTC), letting users share and download files directly in the browser via drag-and-drop or magnet links. It can be self-hosted on your own Node.js server, though most users can simply use the WebTorrent library directly.

Use cases

• send large files to someone without uploading to a cloud service
• download a file from a magnet link in the browser
• share files via a shareable link with an infohash
• seed files from the browser without installing a torrent client
• self-host a WebTorrent-based file transfer site
• transfer files peer-to-peer without a central server holding the data

When to choose

• you want browser-based, plugin-free torrent file sharing
• you need a quick shareable link for peer-to-peer file transfer
• you want to self-host a WebTorrent file transfer service

When to avoid

• you need end-to-end encrypted transfers with persistent links (use Wormhole instead)
• you only need to add WebTorrent file transfer to your own site (use the WebTorrent library directly)
• you need transfers with non-WebRTC torrent peers or traditional BitTorrent client compatibility guarantees
