Non-coders can build low cost DApps with the Nexus Bubble plugin that connects to the Nexus API. Bubble is similar to WIX, though is geared towards building API driven web-apps rather than static pages. If you are familiar with JSON-APIs, you can work directly with the Bubble API connector.
We provide access to a private-mode testnet, if you would like to test or develop the functionality of Nexus without paying fees. Note, our testnet is not permanently maintained, and you are advised to move your DApp to a private network or the public chain when possible.
