Falcon vs Flask: 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, Flask is detailed as "a microframework for Python based on Werkzeug, Jinja 2 and good intentions". Flask is intended for getting started very quickly and was developed with best intentions in mind.

Falcon and Flask belong to "Microframeworks (Backend)" category of the tech stack.

"Python" is the top reason why over 7 developers like Falcon, while over 261 developers mention "Lightweight" as the leading cause for choosing Flask.

Falcon and Flask are both open source tools. Flask with 44.8K GitHub stars and 12.6K forks on GitHub appears to be more popular than Falcon with 6.74K GitHub stars and 700 GitHub forks.

According to the StackShare community, Flask has a broader approval, being mentioned in 502 company stacks & 509 developers stacks; compared to Falcon, which is listed in 7 company stacks and 7 developer stacks.

    Unlike our frontend, we chose Flask, a microframework, for our backend. We use it with Python 3 and Gunicorn.

    One of the reasons was that I have significant experience with this framework. However, it also was a rather straightforward choice given that our backend almost only serves REST APIs, and that most of the work is talking to the database with SQLAlchemy .

    We could have gone with something like Hug but it is kind of early. We might revisit that decision for new services later on.

    We are in the process of building a modern content platform to deliver our content through various channels. We decided to go with Microservices architecture as we wanted scale. Microservice architecture style is an approach to developing an application as a suite of small independently deployable services built around specific business capabilities. You can gain modularity, extensive parallelism and cost-effective scaling by deploying services across many distributed servers. Microservices modularity facilitates independent updates/deployments, and helps to avoid single point of failure, which can help prevent large-scale outages. We also decided to use Event Driven Architecture pattern which is a popular distributed asynchronous architecture pattern used to produce highly scalable applications. The event-driven architecture is made up of highly decoupled, single-purpose event processing components that asynchronously receive and process events.

    To build our #Backend capabilities we decided to use the following: 1. #Microservices - Java with Spring Boot , Node.js with ExpressJS and Python with Flask 2. #Eventsourcingframework - Amazon Kinesis , Amazon Kinesis Firehose , Amazon SNS , Amazon SQS, AWS Lambda 3. #Data - Amazon RDS , Amazon DynamoDB , Amazon S3 , MongoDB Atlas

    To build #Webapps we decided to use Angular 2 with RxJS

    #Devops - GitHub , Travis CI , Terraform , Docker , Serverless

    Review ofFlaskFlask

    Flask is a light, yet powerful Python web framework perfect for quickly building smaller web applications. It's a "micro-framework" that's easy to learn and simple to use, so it's perfect for those new to web development as well as those looking to rapidly develop a web application.

    Jack Littleton uses FlaskFlask

    I use Flask for times when I need to create a REST API that interfaces with other Python code, or there is no specific reason why I'd want to use Node.JS. I prefer Flask because of its small learning curve, allowing me to get started coding as quickly as possible

    This lightweight web framework enables quick REST API development while enabling easy clustering, and the usage of multiple worker processes required to scale the REST API service to meet high volume requirements.
