Share unsigned Applescript app

I have made a few useful Applescript apps. These incorporate shell script and custom binaries, such as ffmpeg and a custom icon, within the bundle.

If I transfer the app to another machine via a USB stick, I can get it to work. If I zip and email the app it is “damaged”.

Is there a way of sharing unsigned apps with colleagues, without having to provide the app on physical media?

Help appreciated.

In answer to my own question…

Gatekeeper is the problem here.

Zip app and upload to webserver.
Download zip in terminal using Curl.
