ButterShare

ButterShare is a browser-based peer-to-peer file sharing tool that lets you send large files and folders directly between devices without uploading them to cloud storage.

Files are transferred through a direct WebRTC connection, helping keep transfers private while avoiding the usual upload-and-download process used by traditional file-sharing services.

There is no account or software installation required. Open ButterShare in your browser, choose the files you want to send, create a secure sharing link or QR code, and let the recipient connect from their device.

ButterShare works across Windows, Mac, Linux, Android, and iPhone browsers, making it useful for transferring photos, videos, project files, large folders, and other files between computers and phones.

It is designed for people who want a simple, private, fast alternative to traditional cloud-based file transfer services.
