Ranked in these QuestionsQuestion Ranking
Pros
Pro Built to build REST APIs
Falcon is designed entirely around building REST APIs. It achieves this helps a lot with it being lightweight and simple. It also helps developers take some design choices which would otherwise not be possible with a more general-purpose framework,
Pro Lightweight with minimal dependencies
Falcon is a very lightweight framework. This can be noticed simply by looking at the dependency list: other than the python standard library, six and mimeparse are the only dependencies.
Pro Performance is really awesome
Pro Fast and getting faster
Thanks to breakthroughs in ROSLYN compiler and the efforts of the .NET COre developer team, code written in C# can reach speeds just a step behind C++.
Pro Multi platform
Can run on Windows, Linux and Mac (also Visual Studio Code editor).
Pro JSON optimization
In .NET Core 2.1 and 3.0, new APIs are added that make it possible to write JSON APIs that require less memory, using Span<T> and UTF8 strings, and improve throughput of applications like Kestrel, ASP.NET Core web server. See also Utf8JsonReader.
Pro Tutorials and documentation quality
Both microsoft and 3rd party tutorials are mostly of high quality and encourage you to use the industry best-practices.
Pro Built-in middleware
Built-in middleware featuring: Authentication, Cookie policy, Health Check, MVC, Session etc.
Pro Hosting
Ability to host on IIS, Nginx, Apache, Docker, or self-host in your own process.
Pro Ease of Use
Pro Security
It is a very secure platform.
Pro Tooling
Both VS and VSCode are powerful free IDEs that are well integrated with ASP.net Core. VS Community also allows for commercial use for projects with less than 5 developers.
Cons
Con Limited in scope
Being designed around building REST APIs and the fact that it's minimalistic with very few dependencies makes Falcon opinionated (you should build a REST API) and limited in scope (you shouldn't be using Falcon to build a news site, blog or ecommerce platform).
Con Microsoft environment
