# eclipse-zenoh — The Zenoh Python API

License: unclear · Maintenance: active · Downloads: 434.4K/mo

## What it is and what it does

Eclipse Zenoh is a Python API wrapping a Rust-native distributed messaging and data system. It provides pub/sub, distributed storage, and query capabilities designed to work efficiently across edge, fog, and cloud environments with minimal overhead. The package is built as a compiled extension (Rust via maturin), so installation depends on either downloading a pre-built wheel for your platform or having a Rust toolchain available to build from source.

The library unifies three traditionally separate concerns—messages in motion, data at rest, and distributed computation—into a single coherent API. It is actively maintained, supports Python 3.8 through 3.12, and runs on Linux (multiple architectures), macOS, and Windows. No runtime Python dependencies are required once installed.

Use it for:

- Build distributed IoT or edge systems where devices need to publish and subscribe to data with minimal latency and resource overhead.
- Implement geo-distributed data synchronization where local storage nodes query and replicate data across multiple sites.
- Create real-time data pipelines that combine messaging, storage, and computation in a single framework without separate infrastructure.
- Deploy low-latency pub/sub systems on resource-constrained platforms (ARM devices, embedded systems) using pre-built wheels.
- Prototype or integrate distributed systems research where traditional pub/sub, databases, and compute layers need tight coupling.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Eclipse Zenoh is a Python binding to a Rust-based pub/sub, storage, and query system that unifies data in motion, data at rest, and computations across distributed environments.

Yes, if you need a unified pub/sub and distributed storage system and can work with Beta-stage software. The active maintenance, current Python version support, platform coverage via pre-built wheels, and zero runtime dependencies make it practical for edge and distributed applications. Verify the dual license (Apache 2.0 / EPL-2.0) terms for your use case first, and confirm your platform has a pre-built wheel to avoid needing a Rust build environment.

## Install

pip install eclipse-zenoh
uv add eclipse-zenoh
poetry add eclipse-zenoh

## Installing eclipse-zenoh

Before you install: Medium install friction: binary wheels are available for common platforms (Linux x86_64, i686, ARM variants, macOS universal2, Windows amd64), but source builds require Rust toolchain and pip >= 19.3.1. Latest release is current.

License in practice: License treatment is unclear: classifiers list both Apache 2.0 and EPL-2.0, but raw SPDX metadata is absent from the package record. Verify the actual license terms before use in proprietary or copyleft-sensitive projects.

Quickstart:

pip install eclipse-zenoh

import zenoh

# Basic session creation
session = zenoh.open()

Requires Python >= 3.8. Building from source requires Rust toolchain and pip >= 19.3.1; pre-built wheels available for most common platforms.

Verify before relying:

- Exact license terms (Apache 2.0, EPL-2.0, or dual) and any compatibility implications for your use case.
- Whether pre-built wheels cover your specific platform/architecture combination.
- API stability and backward-compatibility guarantees given Beta development status.
