filigran-sseclient
Python API client for OpenCTI.
Decision gist · record as of 2026-08-14
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.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.7 or later; requests library must be installed and accessible.
- 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.

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
