Actor Model Python Packages

pykka

🌀 Pykka makes it easier to build concurrent Python applications.

tapio-py

A Pekko-inspired actor toolkit for Python: typed, asyncio-native actors with supervision, Pydantic messages, and point-to-point remoting.

xoscar

Python actor framework for heterogeneous computing.

durable-actors

Durable Actors

casty

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

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.

ankka

A serverless platform for agentic AI on Apache Pekko. Write entities, workflows, agents and endpoints in Scala, Python, TypeScript or Rust, test them without a runtime, and deploy them to Kubernetes with one CLI.

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.

emergent-client

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

atomr

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

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.

aplay

python actor model using asyncio

durable-actors-runtime

Build real-time, multi-agent coordinated systems with great web-socket support

papyra

Durable persistence, retention and compaction for actor systems

rakka

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

rodario

Simple, redis-backed Python actor framework

rakka-accel

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

cohestra-sdk

Open-source deployment management for Apache Flink on any Kubernetes cluster

er-calvin

Calvin is an application environment that lets things talk to things, among other things.

astage

Async actor model library for Python

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

flexplan

Experimental actor-based workflow orchestration
