gevent is a coroutine-based concurrency library for Python built on greenlets, providing a high-level synchronous API on top of libev or libuv event loops. It can monkey-patch the standard library to make blocking I/O cooperative, enabling scalable concurrent network applications.

Use cases

• run thousands of concurrent network connections in python
• make blocking python libraries cooperative without rewriting code
• replace threads with lightweight coroutines for io-bound workloads
• build a high-performance wsgi server in python
• migrate threaded python code to async without callbacks

When to choose

• you have io-bound python code using blocking libraries and want concurrency with minimal changes
• you want a synchronous-style api instead of asyncio's async/await
• you need a battle-tested greenlet-based concurrency solution

When to avoid

• you are starting a new project and can use asyncio from the standard library
• you need cpu-bound parallelism rather than io-bound concurrency
• monkey-patching the standard library is unacceptable in your environment
