Is there really no file size limit? How does this compare to WeTransfer?

Unlike WeTransfer which caps free transfers at 2GB and charges $12/month for larger files, ButterShare has zero file size limits. Files stream directly between your device and the recipient's device with 100% privacy. Because zero bytes are stored on a cloud server, you can send 10GB, 50GB, 100GB, or even larger folders without paying a dime.

Do my files ever get uploaded to your servers?

Never. There is no cloud storage, no database caching, and no file hosting. Our connection broker is only used for a split-second handshake to connect the two browsers. Once the direct connection is open, bytes stream strictly device to device. Zero bytes are ever retained anywhere.

How secure is the transfer? Can anyone intercept my files?

ButterShare uses an encrypted browser connection between the paired devices. File bytes do not sit on ButterShare cloud storage, and the room server only helps the two devices find each other.

Does the recipient need to install an app or sign up?

No. The recipient simply visits ButterShare and enters your 6-character room code (or clicks your share link). The transfer initiates immediately inside their standard web browser on any phone, tablet, or computer. No accounts, no passwords, no app installs.

Can I transfer files wirelessly between any device (Windows, Android, iPhone, Mac)?

Yes, exactly. ButterShare brings seamless, wireless device-to-device file transfer to every operating system. You can send files directly between iPhone, Android, Windows PC, Mac, and Linux with zero cables, app installs, or cloud middleman.

Can I transfer whole folders without zipping them first?

Yes. Drag and drop any folder into ButterShare. It is automatically packaged in your browser and transferred intact with its full folder directory structure preserved.

What happens if someone closes their browser tab during a transfer?

Because files stream directly between devices in real time, both browser tabs must stay open until the transfer completes. If a connection drops, ButterShare alerts you immediately with instant reconnection options. Your original files never leave your device.

Why is ButterShare completely free? What's the catch?

Because ButterShare does not host or store your files on expensive cloud servers (like AWS or Google Cloud), our operating costs are negligible. We don't have massive storage bills to pay, so we never need to charge you subscription fees or limit your file sizes.

Why does Snapdrop say 'No peers found' or fail to discover devices?

Snapdrop uses local device discovery, which can fail if your router isolates Wi-Fi clients, if one device is on 5GHz while the other is on 2.4GHz, or if devices use private Wi-Fi addresses. ButterShare pairs via 6-digit codes or QR codes and can work across more network configurations.

Why does Snapdrop crash when sending large videos or zip files?

Snapdrop accumulates incoming file chunks in browser memory (RAM) as a Blob before saving. On files over 1–2GB, mobile browsers and laptop tabs run out of memory and crash. ButterShare uses the modern File System Access API to stream chunks directly to disk, handling 100GB+ with zero RAM bloat.

Is Snapdrop still active or abandoned?

The original public Snapdrop server has experienced prolonged outages and maintenance lapses. While the code is open-source, the public instance often struggles under traffic. ButterShare is actively maintained with enterprise edge infrastructure.

Snapdrop Alternative (Faster, Reliable, Disk-Streaming)

Why ButterShare

A Simpler, Faster Way to Transfer Files

Snapdrop revolutionized browser device-to-device sharing, but real-world users constantly deal with room setup server downtime, pairing failures across different Wi-Fi bands (2.4GHz vs 5GHz), and browser crashes when files exceed 1–2GB because Snapdrop buffers the entire file in device RAM. ButterShare solves all three: high-availability Cloudflare Durable Object room setup, camera QR room pairing, and memory-safe disk streaming.
