Free | Open Source
The fastest, smoothest way to transfer files to anyone, anywhere.
Your files go straight from device to device - encrypted, with no accounts, tracking, ads, or cloud storage in between.
Think of it like AirDrop for any device, any network.
Free, for files & folders of any size
DashBeam works by connecting sender and receiver directly, so there's no need to upload to a server, which means your transfers are truly private.
Fast
DashBeam can saturate a 4Gbps connection.
Resumable fetching
Interrupted downloads pick up where they left off.
Integrity checks
Data is automatically verified for correctness on both send and receive.
Ways to send
Pick a device. Or send a link.
Three ways to send a file, and no account on either end.
Recommended
Nearby devices
On the same Wi-Fi, your devices just appear. Pick one, confirm a code the first time, and it’s already sending.
Paired devices
Pair once with a short code and they stay paired. Works over the internet, not just the same network. After that it’s one click.
Ticket, link or QR
For anyone else: a one-time link, code, or QR. They install nothing. It opens in their browser.
Platforms
One Experience. Multiple Platforms.
Native apps, a terminal client, and a browser build, all speaking the same protocol.

Native apps for Windows, macOS, and Linux. Drag, drop, and share files instantly with a full desktop experience.
