API Blueprint vs Falcor: What are the differences?

Developers describe API Blueprint as "A powerful high-level API design language for web APIs". API Blueprint is simple and accessible to everybody involved in the API lifecycle. Its syntax is concise yet expressive. With API Blueprint you can quickly design and prototype APIs to be created or document and test already deployed mission-critical APIs. On the other hand, Falcor is detailed as "A JavaScript library for efficient data fetching, created by Netflix". Falcor lets you represent all your remote data sources as a single domain model via a virtual JSON graph. You code the same way no matter where the data is, whether in memory on the client or over the network on the server.

API Blueprint and Falcor belong to "API Tools" category of the tech stack.

API Blueprint and Falcor are both open source tools. It seems that Falcor with 9.36K GitHub stars and 449 forks on GitHub has more adoption than API Blueprint with 7.52K GitHub stars and 2.07K GitHub forks.
