Flask vs Sinatra: What are the differences?
What is Flask? 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.
What is Sinatra? Classy web-development dressed in a DSL. Sinatra is a DSL for quickly creating web applications in Ruby with minimal effort.
Flask and Sinatra can be categorized as "Microframeworks (Backend)" tools.
"Lightweight" is the primary reason why developers consider Flask over the competitors, whereas "Lightweight" was stated as the key factor in picking Sinatra.
Flask and Sinatra are both open source tools. It seems that Flask with 44.8K GitHub stars and 12.6K forks on GitHub has more adoption than Sinatra with 10.6K GitHub stars and 1.89K GitHub forks.
reddit, Lyft, and MIT are some of the popular companies that use Flask, whereas Sinatra is used by SendGrid, thoughtbot, and New Relic. Flask has a broader approval, being mentioned in 502 company stacks & 509 developers stacks; compared to Sinatra, which is listed in 92 company stacks and 33 developer stacks.

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.
Scalatra (we had to pick Sinatra on StackShare since Scalatra is has not yet been officially added) is the slickest (not to be confused with Slick for Scala) web/applet server framework we've had the pleasure of playing with in Scala.
For all intensive purposes, Scalatra is the Scala version of Sinatra (which for anyone who doesn't know is a Ruby web server DSL).
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.

We use Sinatra a lot. I love Sinatra for APIs. It's really simple, really lightweight. It's awesome.
Flask drives our APIs, both the Website APIs and the majority of the REST Messaging APIs
