What is falcon?
Falcon is a lightweight, high‑performance web framework for Python. It helps developers build APIs (the back‑end part of web apps) that can handle lots of requests quickly, without a lot of extra code or heavy libraries.
Let's break it down
- Framework: A set of tools and rules that make it easier to write web services.
- Python‑based: You write your code in the Python programming language.
- WSGI/ASGI compatible: Works with standard Python interfaces for web servers, so you can plug it into many different server setups.
- Minimalist: Provides only the essentials (routing, request/response handling), letting you add extra features only when you need them.
Why does it matter?
Because modern apps often need fast, reliable APIs that can serve many users at once. Falcon’s design focuses on speed and low overhead, which can reduce server costs and improve user experience. It also keeps the codebase simple, making it easier for beginners to understand how web APIs work.
Where is it used?
- Building micro‑services that communicate with each other.
- Creating public RESTful APIs for mobile or web front‑ends.
- Powering internal tools and dashboards that need quick data access.
- Companies like OpenStack, Rackspace, and many startups use Falcon for high‑traffic services.
Good things about it
- Speed: One of the fastest Python web frameworks available.
- Simplicity: Minimal boilerplate; you can get a working API up in minutes.
- Flexibility: Works with any WSGI/ASGI server and lets you add only the libraries you need.
- Clear documentation: Well‑written guides and examples for beginners.
- Scalability: Handles thousands of requests per second with low memory usage.
Not-so-good things
- Limited built‑in features: No built‑in ORM, templating, or authentication; you must add them yourself.
- Steeper learning for advanced needs: When you need complex functionality, you may have to integrate many third‑party packages, which can become confusing.
- Smaller community: Compared to Django or Flask, fewer plugins and community resources exist.
- Less opinionated: While flexibility is a strength, it also means you need to make more architectural decisions yourself.
