Falcon vs Guzzle: What are the differences?

Falcon: 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; Guzzle: PHP HTTP client that makes it easy to send HTTP requests and trivial to integrate with web services. Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and trivial to integrate with web services.

Falcon and Guzzle can be categorized as "Microframeworks (Backend)" tools.

Some of the features offered by Falcon are:

• Intuitive routing via URI templates and resource classes
• Easy access to headers and bodies through request and response classes
• Idiomatic HTTP error responses via a handy exception base class

On the other hand, Guzzle provides the following key features:

• Manages things like persistent connections, represents query strings as collections, simplifies sending streaming POST requests with fields and files, and abstracts away the underlying HTTP transport layer.
• Can send both synchronous and asynchronous requests using the same interface without requiring a dependency on a specific event loop.
• Pluggable HTTP handlers allows Guzzle to integrate with any method you choose for sending HTTP requests over the wire (e.g., cURL, sockets, PHP’s stream wrapper, non-blocking event loops like React, etc.).

Falcon and Guzzle are both open source tools. It seems that Guzzle with 17.1K GitHub stars and 1.95K forks on GitHub has more adoption than Falcon with 6.8K GitHub stars and 707 GitHub forks.

According to the StackShare community, Guzzle has a broader approval, being mentioned in 10 company stacks & 7 developers stacks; compared to Falcon, which is listed in 7 company stacks and 7 developer stacks.
