PostHog vs Amplitude
PostHog and Amplitude are increasingly compared as PostHog has grown into a full product intelligence suite. PostHog combines analytics with session replay, feature flags, and A/B testing - all open-source. Amplitude is the established enterprise product analytics leader with deeper behavioral cohort analysis. The choice often depends on whether you want a multi-tool platform or a specialized analytics tool.

Common questions
For early-stage teams and developer-first companies, PostHog is an extremely compelling choice - it replaces Amplitude, Hotjar, and LaunchDarkly with one open-source tool. For enterprise teams that need Amplitude's depth in cohort analysis and experimentation, Amplitude may still be worth the cost.
Appaca is a third option for teams that don't want to choose between two existing tools. Instead of forcing your workflow into someone else's product, Appaca builds a custom app from a description - with built-in database, hosting, and team access. Try it free at appaca.ai.
