posthog
Integrate PostHog into any python application.
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, carries no security vulnerabilities, has low install friction, and is widely used (top 1000 on PyPI). MIT licensing is permissive. Install it if you need to send analytics or feature flag data from a Python application to PostHog; the minimal dependency footprint and current Python version support make it a straightforward choice.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; PostHog instance or cloud account needed to receive events.
- Low install friction with a pure-wheel distribution.
- Active maintenance with a release 1 day old as of the fact sheet date.

What it is and what it does
PostHog Python is an official SDK that connects Python applications to PostHog, a product analytics and feature management platform. It lets you capture user events, track feature flag evaluations, and send behavioral data to PostHog for analysis and segmentation. The SDK handles HTTP transport via requests, includes automatic retry logic through backoff, and works across modern Python versions (3.10, 3.11, 3.12, 3.13, 3.14).
Typical use cases include tracking user interactions in web services, logging feature flag decisions for A/B testing, and feeding analytics data into product dashboards. The SDK is lightweight, with only four runtime dependencies, and integrates into Django and Flask applications through documented middleware. It's maintained actively and carries no known vulnerabilities.
Use it for
- Track user events and interactions in a web application to build product analytics dashboards.
- Evaluate and log feature flag decisions to measure A/B test performance and feature adoption.
- Capture custom events in backend services to correlate user behavior across multiple systems.
- Integrate PostHog analytics into a Django or Flask application via framework-specific middleware.
- Send event data with custom properties to segment users and build cohorts in PostHog.
