1. Features & Capabilities

PostHog brings together the best of product analytics and experimentation into one cohesive platform. You can track events, analyze funnels, view user paths, and segment behavior with both click and code-based setups. Session recording and heatmaps add visual context to quantitative insights.

But PostHog doesn’t stop there—it includes feature flagging, A/B testing (client and server-side), user surveys, and even error tracking, making it a full-fledged toolkit for teams looking to optimize product experiences end to end.

All modules are deeply integrated. Want to roll out a new feature behind a flag, then measure impact with experiments and feedback surveys? You can do it all in one place.

2. Pricing & Value

PostHog’s pricing model is refreshingly fair. Cloud users get a free tier that includes 1M events, 5,000 session replays, 250 surveys, 100k errors, and more. Beyond that, usage-based rates apply—for example, $0.00005 per event or $0.005 per replay. These rates taper off with scale.

Self-hosting is 100% free under the MIT license but does require server infrastructure (4+ vCPUs and 16+ GB RAM). For high-volume teams, cloud tends to be more scalable and less maintenance-intensive.

3. Ease of Use & Onboarding

If you’re technical, setup is fast—especially for cloud. A single snippet gets you basic tracking, and SDKs are available for React, Next.js, Node, Python, and mobile. You can be collecting data in under 10 minutes.

Self-hosting adds complexity: you’ll need Docker, server knowledge, and time for updates and monitoring. Cloud sidesteps this but trades in predictability for usage billing, so expect to keep tabs on monthly consumption.

4. Case Studies & Reputation

PostHog is used by over 10,000 teams globally—including product-led startups and open-source developers. It consistently ranks high on G2 and Hacker News for “developer freedom,” “open data,” and “best stack consolidation.”

Users report launching successful A/B tests and consolidating multiple SaaS costs into one platform. It’s especially praised for its robust pathing, feature flag targeting, and SQL support.

5. Customer Support & Reliability

Cloud support includes email and community help. Enterprise support with SLAs only kicks in at the $2,000/month level. Self-hosters rely on GitHub issues and the PostHog forums, which are active but not SLA-backed.

Cloud uptime and security are solid—GDPR/CCPA compliant, with data region control. But if you’re self-hosted, you’re also self-responsible for availability and scaling.

6. Summary & Final Rating
