Actor Model Python Packages

pykka

🌀 Pykka makes it easier to build concurrent Python applications.

xoscar

Python actor framework for heterogeneous computing.

atomr-infer

Multi-runtime GPU + remote inference as a supervised actor system on atomr. OpenAI / Anthropic / Gemini / LiteLLM remote runtimes + vLLM / TensorRT / ORT / mistral.rs local; remote-only build compiles zero GPU deps.

atomr-agents

A composable agentic framework on atomr actors and atomr-infer. Channelled state with checkpointing, dynamic HITL, retriever zoo, parallel tool dispatch, eval suites — the LangGraph + LangChain feature set in atomr's actor idiom.

casty

A minimalist, type-safe actor framework for Python 3.12+ with built-in distributed clustering

atomr-accel

Actor-shaped face for compute acceleration backends (NVIDIA CUDA shipping; ROCm / Metal / oneAPI / Vulkan future). Built on the atomr actor runtime.

atomr-view

Actor-based View Management for the atomr ecosystem

rakka-inference

Multi-runtime GPU + remote inference as a supervised actor system on atomr. OpenAI / Anthropic / Gemini / LiteLLM remote runtimes + vLLM / TensorRT / ORT / mistral.rs local; remote-only build compiles zero GPU deps.

atomr

A native Rust runtime for actor-based concurrent and distributed systems, with first-class Python bindings. A Rust port of Akka.

aplay

heddle-ai

Actor-based Python framework for orchestrating multi-LLM AI workflows via NATS messaging. Stateless workers, strict I/O contracts, deterministic routing, pipeline orchestration, and self-checkpointing context management

emergent-client

Event-driven workflow engine with three primitives: Sources, Handlers, and Sinks

rodario

Simple, redis-backed Python actor framework

distributed structured concurrency

er-calvin

Calvin is a distributed runtime and development framework for an actor based dataflowprogramming methodology

astage

Async model actor library

loom-ai

Actor-based Python framework for orchestrating multi-LLM AI workflows via NATS messaging. Stateless workers, strict I/O contracts, deterministic routing, pipeline orchestration, and self-checkpointing context management

pyctor

Minimalistic implementation of the actor concurrency model powered by asyncio.

flexplan

Experimental actor-based workflow orchestration

jockey

🏇 Generic Python library for running asynchronous workers. Useful for building event handlers, web frameworks, and alike.

papyra
