# zope.publisher — The Zope publisher publishes Python objects on the web.

License: unclear · Maintenance: active · Downloads: 182.3K/mo

## What it is and what it does

zope.publisher is a web request/response handler that sits between HTTP clients and Python application objects. It parses incoming HTTP requests (including multipart form data and file uploads) into request objects and manages response serialization, supporting multiple client types—browsers, XML-RPC clients, WebDAV, and FTP—through a unified WSGI-compatible interface. The package is part of the Zope ecosystem and provides the foundational request/response machinery for web frameworks built on Zope.

The package has been actively maintained since 2007, with recent updates focused on Python 3 compatibility and modern standards compliance. It handles character encoding, file uploads via the multipart library, and request/response lifecycle management. Its 12 runtime dependencies are all from the zope namespace, making it tightly integrated with the Zope component architecture. The recent version 8.1 dropped Python 3.9 support and added Python 3.14 support, reflecting active alignment with current Python releases.

Use it for:

- Build a Zope-based web application that needs to parse HTTP requests and manage responses for browser clients.
- Handle multipart form data and file uploads in a web framework that integrates with the Zope component architecture.
- Expose Python objects via XML-RPC or WebDAV protocols alongside standard HTTP/browser access.
- Implement custom request/response handling by subclassing BrowserRequest or BaseRequest for specialized encoding or security policies.
- Migrate a legacy Zope application to modern Python (3.10+) while preserving request/response semantics.

## Worth the install?

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

zope.publisher handles HTTP request and response objects for publishing Python objects on the web, with support for HTTP/WebDAV, browsers, XML-RPC, and FTP clients via a WSGI-compatible interface.

Yes, if you are building or maintaining a Zope-based web application or framework. The package is actively maintained, has no known vulnerabilities, and supports current Python versions. The unclear license treatment warrants a quick verification, but the ZPL-2.1 license itself is permissive. Install friction is low. Not recommended for new projects outside the Zope ecosystem—modern alternatives like Werkzeug or Starlette are more widely adopted.

## Install

pip install zope-publisher
uv add zope-publisher
poetry add zope-publisher

## Installing zope.publisher

Before you install: Low install friction with a pure-Python wheel. Active maintenance with recent release (51 days old); supports current Python versions (3.10–3.14) and drops older versions regularly. Depends on 12 zope ecosystem packages, all part of a mature, coordinated namespace.

License in practice: Licensed under ZPL-2.1 (Zope Public License 2.1), a permissive open-source license. License treatment is marked unclear in the metadata, so verify compatibility with your project's licensing requirements before use.

Quickstart:

pip install zope.publisher

from zope.publisher.http import HTTPRequest
from io import BytesIO

request = HTTPRequest(BytesIO(), {})

Requires Python 3.10 or later; depends on multipart library for form data parsing.

Verify before relying:

- Whether the unclear license treatment reflects actual ambiguity or is a metadata artifact.
- Real-world performance and stability with the multipart 1.0.0+ strict line-ending requirements.
- Compatibility of the PEP 420 namespace migration (version 8.0) with existing deployments.
