BridgeDrop version 0.1.0

Send a file straight to someone.

No upload, no size limit, no account. The file leaves your machine and arrives on theirs.

What you get

A single application, about 7 MB. It runs on your machine and nowhere else.

No size limit

There is no upload step to impose one. Tens of gigabytes in a single transfer is ordinary use.

Nothing is stored

No server holds your files, because there is no server. Nothing to leak, expire, or be handed over.

Encrypted twice over

The connection is encrypted, and every chunk is sealed separately. A machine relaying the traffic sees only ciphertext.

Resumes where it stopped

Close the lid, lose the Wi‑Fi, come back tomorrow. It continues from the last verified chunk.

Finds devices nearby

Machines on the same network see each other with nothing to configure. You send; the other side accepts.

Works across networks

Different cities, different networks: share a link and the two machines find a route between themselves.

The first time you open it

This build is not yet signed with a paid developer certificate, so both systems will warn about it. The warning is about the certificate, not about anything found in the file — but only click through it for software you meant to download.

Windows

“Windows protected your PC”

  1. Click More info.
  2. Click Run anyway.
  3. Allow it through the firewall when asked. Without that, other devices cannot reach you.

macOS

Signed and notarised by Apple — opens like any other app.

  1. Open the DMG, drag BridgeDrop to Applications.
  2. Allow local network access when asked. That is how it finds nearby devices.

Check what you downloaded

Compare the hash of your file against the one published here. If they differ, do not run it.
