PostHog vs Plausible: Product or Web Analytics?
Choose PostHog when product events, replay, and release measurement need connected analysis. Choose Plausible when the core requirement is focused, privacy-oriented website traffic and conversion reporting.
For a SaaS business, the marketing site and logged-in application ask different measurement questions. Website acquisition reporting may not need the same identity and event detail as activation analysis. Decide which question this purchase must answer before comparing the size of the product suites.
PostHog
PostHog combines product analytics, web analytics, session replay, flags, experiments, and other product-development capabilities. Teams can relate behavioral data to release decisions in one platform. A focused rollout should start with a defined event and identity model, because collecting more telemetry does not automatically make the numbers useful.
Plausible
Plausible focuses on straightforward website analytics with a privacy-oriented, cookieless collection model. It helps teams understand traffic, sources, and conversions without starting from a large product instrumentation program. That scope can suit a public marketing site; evaluating a logged-in product journey may require a different level of event and identity detail.

PostHog pros
Analytics and release capabilities can share product context.
Replay can add behavioral detail to an analytics investigation.
Several products allow a team to adopt capabilities as needed.
PostHog cons
Broad product scope needs a deliberate instrumentation and ownership plan.
Event volume and optional product usage can change ongoing cost.
Pricing: Review product-specific usage pricing and free allowances. Estimate events, recordings, feature usage, and retention separately rather than treating the suite as one flat fee.
Plausible pros
A focused website dashboard supports routine traffic review.
Cookieless collection is central to the privacy-oriented product approach.
A narrow analytics scope can simplify a marketing-site reporting workflow.
Plausible cons
Website traffic reporting is a different need from detailed product journey analysis.
Privacy decisions still depend on your actual deployment and data collection.
Pricing: Check current traffic-based service terms and any required capabilities. Treat hosted analytics and operating a self-managed version as different cost and maintenance choices.
