napari-stream

A plugin to send and receive image data for visualization in Napari from other applications.

napari-stream lets you push images from any application, process, or codebase into a running napari instance—even from another machine. It can automatically pull array-like data (NumPy, PyTorch tensors, zarr arrays, etc.) from nested Python lists and dicts, so you can stream complex structures without manual extraction. You can keep things private (local IPC/loopback) or make the receiver reachable publicly over TCP. The receiver endpoint can also be set via the NAPARI_STREAM_ENDPOINT environment variable.

Quick usage

from napari_stream.sender import StreamSender, send
import numpy as np

# Option 1: explicit sender (recommended when reusing across many sends)
sender = StreamSender(endpoint="tcp://192.0.2.10:5556")  # or leave None to use NAPARI_STREAM_ENDPOINT/default
sender.send(np.random.rand(256, 256), name="image")

# Option 2: convenience function; pass connection kwargs through
send(np.random.rand(64, 64), name="quick", endpoint="tcp://127.0.0.1:5556")

On the receiving side, open the napari dock widget, choose your endpoint, and toggle public access if you want to accept connections from other machines.

Installation

You can install napari-stream via pip:

pip install napari-stream

If napari is not already installed, you can install napari-stream with napari and Qt via:

pip install "napari-stream[all]"
