To be clear, we aren&#x27;t exclusively for open source apps. We in fact have one proprietary app on the app market today (draw.io).<p>We want to help developers get paid for their work by making it really easy to get paid. Sandstorm Oasis users will already have a credit card on file; we want to make it easy for them to use that card for in-app purchases. In the case of open source apps, we want to make it easy for app developers to solicit &quot;tips&quot;, perhaps by implementing this as part of the Sandstorm UI -- if you use an open source app a lot, the UI could (hopefully not overly intrusively) say &quot;Hey, would you consider giving a weekly tip to this developer?&quot;<p>I&#x27;ve also thought about a &quot;spotify&quot; model where we automatically pass along some portion of subscription fees to apps that get used a lot.<p>Of course, things are more complicated for personal servers where the user doesn&#x27;t necessarily have payment methods on file. We&#x27;re still thinking about how that will work, but we&#x27;ll come up with something.
