PostHog

PostHog is an open-source product analytics platform. It helps teams track user behavior inside their apps. It solves the problem of needing multiple tools to understand how users interact with a product.

Features

• Session Recording: Captures real user sessions as video replays. Teams can watch exact clicks, scrolls, and rage-clicks without extra setup.
• Feature Flags: Lets developers roll out new features to specific user groups. Supports percentage-based rollouts and targeting by user properties.
• A/B Testing: Runs controlled experiments directly inside the platform. Results link back to analytics data for clear impact measurement.
• Event Autocapture: Automatically tracks clicks, form submissions, and pageviews. No manual event tagging is required for basic tracking.
• Data Pipelines: Exports data to warehouses like BigQuery, Snowflake, and Redshift. Supports webhooks and integrations with tools like Slack and Zapier.

Use Cases

• For Product Managers: Track feature adoption rates and measure how changes affect user retention over time.
• For Developers: Use feature flags to safely deploy code and roll back instantly if problems appear.
• For Startups: Access a self-hosted, open-source stack that avoids sending user data to third-party servers.
• For Growth Teams: Run A/B tests and analyze funnel drop-offs without switching between separate tools.

PostHog combines analytics, session recording, and experimentation into one open-source platform. It suits teams that want full data control without relying on multiple vendors.
