filigran-sseclient

What it is and what it does

Filigran-sseclient is a Python library that wraps HTTP Server Sent Event (SSE) streams into a simple iterator interface. You pass it a URL, and it yields individual messages as they arrive from the server, handling the SSE protocol parsing for you. It depends on requests for HTTP transport and six for Python 2/3 compatibility (though the package itself requires Python 3.7+).

The library is a fork of the original sseclient project, with enhancements to support chunk stream messages—useful when servers send SSE data in multiple chunks rather than as complete lines. It's classified as production-stable and sits in the top 5000 PyPI packages by download volume, suggesting moderate adoption for real-time event consumption use cases.

Use it for:

• Consume real-time event streams from platforms that expose SSE endpoints for live data delivery
• Build monitoring dashboards that subscribe to live server-sent updates without polling
• Process continuous data feeds (logs, metrics, alerts) streamed over HTTP in SSE format
• Integrate with APIs that use EventSource for push notifications or live data delivery

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides a Python iterator interface for consuming Server Sent Event (SSE) streams over HTTP, with support for chunk stream messages.

Yes, if you need to consume SSE streams over HTTP. The package is lightweight, permissively licensed, and has no known vulnerabilities. Install friction is low. However, note that maintenance is aging (last commit 2025-11-28) and the project has minimal community engagement (1 star), so expect limited ongoing support or feature development—suitable for stable, read-only SSE consumption but not for packages requiring active maintenance.

Install

filigran-sseclient on PyPI

pip install filigran-sseclient

uv add filigran-sseclient

poetry add filigran-sseclient

Installing filigran-sseclient

Before you install

Low friction installation with only two lightweight runtime dependencies (requests and six). Maintenance status is aging—last commit was 2025-11-28, but the package has remained stable since its first release in 2023-02-23.

License in practice

Licensed under MIT (permissive), allowing free use, modification, and distribution with minimal restrictions.

Quickstart

pip install filigran-sseclient

from sseclient import SSEClient

url = 'https://example.com/stream'
client = SSEClient(url)
for message in client:
    print(message.data)

Requires Python 3.7 or later; requests library must be installed and accessible.

Verify before relying

• Whether chunk stream message support is complete or still experimental relative to the original sseclient fork
• Performance characteristics when handling high-volume or long-lived SSE connections
• Whether the package is actively maintained or in maintenance-only mode given the aging status
