Falcon vs Rails API: What are the differences?
Developers describe Falcon as "High-performance Python framework for building cloud APIs and web app backends". Falcon is a minimalist WSGI library for building speedy web APIs and app backends. We like to think of Falcon as the Dieter Rams of web frameworks. On the other hand, Rails API is detailed as "Rails for API only applications". Rails::API is a subset of a normal Rails application, created for applications that don't require all functionality that a complete Rails application provides. It is a bit more lightweight, and consequently a bit faster than a normal Rails application. The main example for its usage is in API applications only, where you usually don't need the entire Rails middleware stack nor template generation.
Falcon and Rails API can be primarily classified as "Microframeworks (Backend)" tools.
"Python" is the top reason why over 7 developers like Falcon, while over 4 developers mention "Great for quick decoupled apps" as the leading cause for choosing Rails API.
Falcon and Rails API are both open source tools. Falcon with 6.8K GitHub stars and 707 forks on GitHub appears to be more popular than Rails API with 5.26K GitHub stars and 293 GitHub forks.
