Yes you can use Justuno on multiple sites! You can manually embed Justuno on the sites just as you did your first site (for Shopify customers that used the app, check out the article that walks you through manually embedding Justuno). Then if you want to use different designs on different sites you can use advanced rules to segment the overlays on each site.
OPTION A: Using "Basic Rules"
The concept here is that you will tell the overlays to show on XYZ site but also NOT show on ABC site. For example, if we had two sites sugartree.com and the other buddhatree.com here is how to rule for sugartree.com would look.
Opening the options under "refine options" drops down the options to show on specific pages and don't show on pages. Using contains instead of equals here, will allow you to show on any portion of the site. For example if you are using an exit offer rule for the sugartree site, here is how to rule would look!
OPTION B: Using "Advanced Rules"
The concept here is that you will tell the overlays to show on xyz site but also NOT show on abc site. For example, if we had two sites sugartree.com and the other buddhatree.com here is how to rule for sugartree.com would look.
The condition current url "does not contain buddhatree" tells the overlay to NOT show on anything that contains buddhatree, meaning the entire site. Then the condition current url "contains sugartree" is telling the promotion to only show on anything that has sugartree, meaning the whole site! This set up can be applied to any rule set, but it must be included in ALL rules if there are multiple set up for each promotion.
For the buddhatree site where I only want to use an exit offer, here is what the rule would look like:
The same concept can be added to the tab display like so:
