## What it is
Pykka is a Python implementation of the actor model, providing actors that communicate via messages to simplify building concurrent applications. It has no dependencies beyond Python 3.10+ and is distributed on PyPI under the Apache 2.0 license.

## Use cases
- build concurrent python applications
- implement the actor model in python
- avoid shared-state race conditions between threads
- coordinate parallel tasks via message passing
- structure a python app as independent actors

## When to choose
- you want actor-model concurrency in pure Python with zero dependencies
- you prefer message passing over locks and shared mutable state
- you need a lightweight, well-documented concurrency library

## When to avoid
- you need distributed actors across multiple machines
- you need high-throughput async I/O rather than actor-style coordination
- your project must support Python versions older than 3.10

## Facets
- artifact type: library
- maturity: active
- function: concurrency
- domain: developer-tools
- platform: python, cross-platform
- tags: actor-model, threading, message-passing, algorithms
