Our top 2 FullStory alternatives
PostHog is an open-source analytics and product-tooling platform written primarily in Python, with JavaScript and React components for client-side instrumentation. It lives in the web and product analytics ecosystem, and it also reaches into session replay, experimentation, error tracking, log ingestion, customer data pipelines, and LLM observability. Rather than stitching together a separate tool for each of those jobs, PostHog captures event data once and lets teams query it alongside data synced from external sources such as Stripe and Hubspot.
