They are attempting to solve similar problems: describing data needs on a client in a way that integrates well with how the data is used, and fulfilling those requirements efficiently.

Falcor uses some different primitives to accomplish the task, focusing on connecting together Observables, whereas GraphQL queries are written in a small query language.

Falcor is a super interesting project and we've gotten to swap notes a couple times.

Awesome, thanks. I watched the Falcor presentation and had my mind blown; looking forward to a similar explanation of GraphQL.
