Helicone's founding engineer, Stefan Bokarev, shares his enthusiasm for PostHog, an open-source product analytics tool that has significantly enhanced Helicone's workflow since its adoption. Chosen for its affordability, growth potential, and comprehensive features, PostHog has enabled Helicone to effectively monitor both backend and frontend events, create custom dashboards for marketing and LLM analytics, and utilize features like Session Replay to optimize user experience. Both the CEO and co-founder of Helicone appreciate PostHog's value in providing clear product analytics and insights into marketing campaigns and conversions. The tool's ability to trace user journeys and integrate easily with Helicone's systems makes it a versatile choice for developers at any stage. Bokarev highlights the importance of starting with dashboards and Session Replays for those with LLM applications, and he emphasizes the principle of prioritizing "good enough" over perfection in a startup environment. Helicone recently launched an integration with PostHog for capturing LLM metrics, further demonstrating its commitment to leveraging PostHog's capabilities.
