APIXIS

Event-driven graph orchestration for Python asyncio applications.

PyPI Python License

Source · Issues · API Reference

APIXIS provides two composable runtimes:

  • an asynchronous event system with wildcard subscriptions, ordered handlers, backpressure, and pluggable channels;
  • a stateful graph runtime with Command-driven steps, parallel nodes, snapshots, streaming, and interruption/resume workflows.

Python 3.12+ is required. Runtime APIs are designed for asyncio.

Install

pip install apixis

To install a local checkout, run from the repository root:

python -m pip install .

For development and release tools:

python -m pip install -e ".[dev]"
python -m pytest

With uv, use uv sync --extra dev --locked and uv run --extra dev pytest. See the release guide for building and publishing to PyPI.

Quick start

import asyncio

from apixis import GraphManager


def increment(state: dict) -> dict:
    return {"value": state["value"] + 1}


async def master() -> None:
    graph = (
        GraphManager()
        .add_node(increment)
        .compile_graph(entry_point="increment")
    )
    try:
        result = await graph.invoke({"value": 1})
        print(result)  # {'value': 2}
    finally:
        graph.decompose()


asyncio.run(master())
