ButterShare

ButterShare is a browser-based peer-to-peer file transfer tool that lets you send large files and folders directly between devices without creating an account or uploading them to traditional cloud storage.

ButterShare uses WebRTC to establish direct connections between devices whenever possible, allowing files to move from the sender to the receiver without being permanently stored on ButterShare's servers.

To share a file, users simply select the files or folders they want to send, generate a sharing link or QR code, and send it to the recipient. The recipient opens the link in their browser and the transfer can begin.

ButterShare works across Windows, macOS, Linux, Android, and iOS through modern browsers, so there is no need to install a dedicated application.

It is useful for creators, freelancers, remote teams, designers, photographers, developers, students, and anyone who regularly needs to transfer large files between devices.
