# Stackless Python

5 Hacker News commenters recommended Stackless Python and 1 criticized it, November 2025 to November 2026. It was recommended in 2 of 13 months.

**Verdict:** People recommend it for tasklets that can be serialized and moved to another machine, making it a good fit for long-running stateful work. Its main drawback is that it has not kept pace with mainstream Python, and some developers have moved away from it.
