Hi Killian, 

>> And is your question whether you can use a widget created in OutSystems on another non-OutSystems web site? 

This is exactly what I'm talking about. Is this still the case? Many low code solutions allow you to build apps/widgets and then render them in an external site either by iframe or a code snippet/tag that pulls the html from the widget into your site.

Yes, that's still the case, and it won't change. OutSystems is not a widget builder.

Yes you can render any page in Outsystems in an iframe just as in any other website, you just can't deploy your actual Outsystems code to their server.. It is still running on your server. Because the iframe and other page will have different domains you will however need to worry about Cross Origin Resource Sharing issues.
