After you've created a project in ExploreMyPC, most likely you'll want to publish it. In order to do that you need to press the Publish link:
You can't link any custom domains in the Free plan, 1 custom domain in the Personal, 20 custom domains in Freelancer plan 100 custom domains in Agency plan.
ExploreMyPC Free account: you can't link any custom domains
ExploreMyPC Personal plan: you can link 1 custom domain
ExploreMyPC Freelancer plan: you can link 20 custom domains
ExploreMyPC Agency plan: you can link 100 custom domains
* The number of domains or subdomains you can link can differ based on other promotions or deals you've purchased outside ExploreMyPC (an AppSumo deal for example).
Publishing on a ExploreMyPC is free and will let you host unlimited websites on a ExploreMyPC.site subdomain of your choice.
Important: Both Custom Domain and ExploreMyPC Subdomain publishing options come with free SSL included. Takes up to 24 hours to be installed. More about the Free SSL here.
Export HTML
The Export HTML publishing option lets you download a .zip file containing the HTML files of your project.
