As you start building out your microapp, you can test the behavior every step of the way. To make sure all of your hotspots are linking to the right pages, videos autoplaying, hovers hovering, etc. simply click the Preview (play button) ▶️ in the upper right-hand corner of the builder.
This will take you into Preview Mode to test the output as you continue to make changes. To return back to the builder, simply click the Exit (back to builder) button.
Note: If you want to share your work, copy / pasting the app.tiled.co URL in the Builder / Preview Mode will direct your recipients to login to Tiled (i.e. for your teammates and fellow Tiled users).
If you're wanting to send a link to a counterpart who does not have a Tiled login - you'll want to publish your project and create a share link to use instead. You can see more on generating share links, here.
