KRATE

Someone sent you an app.

It is one small file, like a photo. To open it you need Krate once -- like a player for a movie. After that, every app anyone sends you just opens, and each one tells you what it wants first.

1

Get Krate, once

Free and open source. This is the only setup there is: after it, every app anyone ever sends you is just a double-click.

Download Krate

Comfortable in a terminal instead?

curl -fsSL https://krate.tech/install.sh | sh
irm https://krate.tech/install.ps1 | iex
2

Double-click the file

The same as a document or a photo. Nothing to unzip, nothing to install per app, no developer tools.

3

Decide what it may do

Before any of the app runs, a window like this appears. The app opens with exactly what you allow -- it cannot reach the internet, or any other folder on your computer.

“Notes” wants to:

read files in its notes folderto load the notes you saved before
save files in its notes folderto keep the note you are writing
use your clipboardto copy and paste inside the app
Allow and open

It gets nothing else: no files, no internet, no camera.
