# gevent

7 Hacker News commenters recommended gevent and 5 criticized it, November 2025 to November 2026. It was recommended in 4 of 13 months.

**Verdict:** Python library that lets synchronous-looking code handle many I/O-bound tasks; fans prefer it over async syntax, while critics object to its implicit, stdlib-patching behavior.

## Why people recommend it

- Synchronous-looking code, no async syntax (4 comments): "Goroutines and gevent greenlets work seamlessly with synchronous code, with no headache." ([source](https://news.ycombinator.com/item?id=48021151)) "I prefer gevent over explicit async so I'll die on that hill with you." ([source](https://news.ycombinator.com/item?id=46155954)) "you can blissfully ignore all of that if you use gevent" ([source](https://news.ycombinator.com/item?id=45806960))
- Handles I/O-bound request load well (2 comments): "Still alive and kicking in production for us! For situations where many requests are bound by external HTTP requests" ([source](https://news.ycombinator.com/item?id=46249141)) "you might benefit from moving to gevent and handle that load with just a handful of containers" ([source](https://news.ycombinator.com/item?id=46092251))
- Strong personal endorsements from fans (2 comments): "I prefer gevent over explicit async so I'll die on that hill with you."

## What people warn about

- Implicit concurrency hard to reason about (2 comments): "it can make it much harder to look at some code and figure out what execution model it's going to run with" ([source](https://news.ycombinator.com/item?id=48021388)) "Implicit management of async operations is something I hope I never have to deal with again."
