Overview

ato.run is a web app for trying, keeping, and sharing software that runs on Ato. Ato treats software as a continuation: the work that remains from a given point, which can be sealed, carried, and resumed instead of being reduced to a hosted endpoint.

You do not need to know that model to use the app. Start with the steps below, and follow the developer guides only if you want to know what a Capsule is or how to seal one yourself.

Try your first app

Open Discover.
Choose Explore to reach the app cards.
Choose Open on a card.

Keep an app you want to reuse

Choose Add to Library below an app to save your own copy. A copy keeps your data separate from a public trial and stays in your account.
