gevent vs greenlet

Struggling to choose between gevent and greenlet? Both products offer unique advantages, making it a tough decision.

gevent is a Development solution with tags like networking, async, event-loop, nonblocking.

It boasts features such as Coroutine-based concurrency, Fast event loop based on libev, Lightweight execution units, API that reuses concepts from the Python standard library, Cooperative multitasking and pros including High performance, Easy to use API, Integrates well with existing Python code, Allows blocking calls to be non-blocking, Built-in support for common network protocols.

On the other hand, greenlet is a Development product tagged with concurrency, coroutines, multitasking.

Its standout features include Lightweight concurrency library, Allows switching between green threads (coroutines), Enables non-blocking cooperative multitasking, Similar to using yield statements for cooperative multitasking, and it shines with pros like Lightweight and fast, Simple API, Integrates well with Python generators, Can prevent blocking I/O calls from blocking entire application.

To help you make an informed decision, we've compiled a comprehensive comparison of these two products, delving into their features, pros, cons, pricing, and more. Get ready to explore the nuances that set them apart and determine which one is the perfect fit for your requirements.

gevent

gevent

gevent is a Python networking library built on top of libev event loop. It provides a high-level synchronous API on top of libev's asynchronous event loop, making it easier to write non-blocking network applications in Python.

Pros

Lightweight and fast

Simple API

Integrates well with Python generators

Can prevent blocking I/O calls from blocking entire application

Cons

Not true parallelism like with threads or processes

Requires restructuring code to use coroutines

Debugging can be more difficult than with threads
