Open-source product analytics, session replay, feature flags, and experiments — self-host or use the cloud.
The product analytics suite that ate three categories
PostHog has quietly become the default for product analytics, session replay, feature flags, and experiments in one tool. Each individual product is good enough, the bundle is undefeatable on price, and self-hosting is genuinely viable.
The leading customer data platform — collect, clean, and connect customer data to all your tools.
The original CDP — increasingly displaced by warehouse-native alternatives
Segment created the CDP category and remains the broadest deployed. Twilio ownership has slowed innovation, and warehouse-native alternatives (Hightouch, Census + Snowflake) deliver the same activation outcomes for less money in 2026.
Reverse ETL and data activation — governed sync from warehouse to 200+ SaaS tools with dbt-first workflows.
Enterprise CDP with strong mobile SDKs — collect, route, and govern customer data across digital properties.
Auto-capture product analytics — records every user action so you can retroactively analyze anything.
Open-source Segment alternative — customer data pipeline with warehouse-first architecture.
