Here's the thing about a product like yours. If you're going to expect developers to use your tool, you need to solve the problems developers don't want to do themselves. For example, I like building UI components, so I would never use a platform that forced me to choose from their list of components. For a low code tool to be worth it, it needs to replace a part of the job that I hate, not replace a skillset that I've been lovingly perfecting for years. You need to make it so I don't have to learn something boring, not make all my knowledge useless.

Your customer is not me. Your customer is a PM who can't build but can make the decision to adopt, or a small business owner who doesn't have money to hire real engineers. Just like how Ikea's customer base is largely made of people who don't already know how to build furniture.
