How do PostHog's feature flags compare to Clarity's lack thereof?

PostHog offers robust feature flag functionality, including A/B testing and multivariate flags, allowing for targeted feature rollouts and experimentation. Microsoft Clarity lacks any feature flag capabilities, limiting its usefulness for controlled releases and A/B testing of new features. This makes PostHog a better choice for teams looking to manage feature releases and conduct experiments, while Clarity is more focused on understanding existing user behavior.

Which product best integrates session recordings with product analytics?

PostHog more tightly integrates session recordings with product analytics. PostHog's all-in-one design explicitly connects session recordings with product analytics features like funnels and user paths, allowing for a more seamless workflow when analyzing user behavior. While Microsoft Clarity offers session recordings and integrates with Google Analytics, it doesn't natively connect the recordings with its own analytics in the same comprehensive way as PostHog.

What are the advantages of PostHog?

PostHog's advantages include its all-in-one platform approach, combining product analytics, A/B testing, and feature flagging. Its open-source nature allows for self-hosting, customization, and a generous free tier, making it appealing to smaller teams or those with specific data privacy needs. PostHog also excels in session recording capabilities, providing detailed insights into user behavior.

What are the disadvantages of PostHog?

PostHog's self-hosted version lacks some features available in the cloud version. The documentation can be inconsistent with outdated or duplicated information, making it difficult to find accurate guidance. Community support, while present, can sometimes be slow or unresponsive. Finally, the large Javascript bundle size can negatively impact website performance.
