PostHog
Open source product OS.
What it is
PostHog is the 'all-in-one' product analytics suite for developers and modern startups. Unlike Google Analytics, which focuses on traffic, PostHog focuses on user behavior within your product. It combines powerful features like event tracking, session recordings, heatmaps, and feature flags into a single, open-source platform. It allows teams to build better products by understanding exactly how users interact with every feature, and even run A/B tests to see what works best.

Strengths and trade-offs
What works well
- All-in-One: Replaces 5-6 different tools (Mixpanel, Hotjar, LaunchDarkly, etc.).
- Open Source: You can self-host it to ensure total data privacy and control.
- Powerful Free Tier: Extremely generous free plan for startups just starting out.
- Developer First: Built with a modern API and great documentation for engineers.
Where it falls short
- Complex UI: The sheer number of tools can make the dashboard feel cluttered.
- Learning Curve: Mastering advanced queries and funnel analysis takes effort.
- Self-Hosting: Managing a high-traffic PostHog instance yourself is a technical challenge.
Who it is for
Product Managers, Developers, and Growth Teams.

Pick PostHog if
- Startups that want product analytics, session replay, feature flags and error tracking from one vendor

Skip it if
- You need more than 1 project or over 1 year of retention without adding a card
- You want a fixed monthly bill — costs scale per product once free allowances are exceeded
- You need enterprise procurement and a signed SLA before use
