It's difficult to say for certain whether low-code platforms have leaky abstractions or not. In general, however, low-code platforms are designed to provide a large set of abstractions that make it easier for non-technical users to build and customize software applications without having to write code. These abstractions can help to hide the underlying details of the system and make it easier for users to work with, but it's possible that some of the underlying details may still be exposed, leading to "leaky abstractions." Ultimately, the extent to which low-code platforms have leaky abstractions will depend on the specific implementation and design of the platform in question.
