Colossus vs Tastypie: What are the differences?

Developers describe Colossus as "I/O and Microservice library for Scala". Colossus is a lightweight framework for building high-performance applications in Scala that require non-blocking network I/O. In particular Colossus is focused on low-latency stateless microservices where often the service is little more than an abstraction over a database and/or cache. For this use case, Colossus aims to maximize performance while keeping the interface clean and concise. On the other hand, Tastypie is detailed as "Creating delicious APIs for Django apps since 2010". Tastypie is a webservice API framework for Django. It provides a convenient, yet powerful and highly customizable abstraction for creating REST-style interfaces.

Colossus and Tastypie belong to "Microframeworks (Backend)" category of the tech stack.
