Flask vs. Ruby Grape vs. Rustless vs. dbForge Query Builder for MySQL Comparison Chart

Flask is a lightweight WSGI web application framework. It is designed to make getting started quick and easy, with the ability to scale up to complex applications. It began as a simple wrapper around Werkzeug and Jinja and has become one of the most popular Python web application frameworks. Flask offers suggestions, but doesn't enforce any dependencies or project layout. It is up to the developer to choose the tools and libraries they want to use. There are many extensions provided by the community that make adding new functionality easy.

Rustless is a REST-like API micro-framework for Rust. It's designed to provide a simple DSL to easily develop RESTful APIs on top of the Iron web framework. It has built-in support for common conventions, including multiple formats, subdomain/prefix restriction, content negotiation, versioning, and much more. Rustless in a port of Grape library from Ruby world. Based on hyper, an HTTP library for Rust. Like Rust itself, Rustless is still in the early stages of development, so don't be surprised if APIs change and things break. If something's not working properly, file an issue or submit a pull request! Rustless is based on Iron, which is based on Hyper, which is synchronous. Hyper has a lot of limitations right now, and can't handle many simultaneous connections, especially with keep-alive. So it is highly recommended to use a light asynchronous web server such as Nginx as a reverse proxy server with Rustless.
