PostHog

“Product Analytics turns what people do in your product into answers you can act on. Autocapture tracks pageviews, clicks, and form submissions without extra code. From there you build trends, funnels, retention curves, paths, and SQL queries – then jump straight into the session recordings behind any data point when you need the 'why'.”

“Set filters for individual steps – or the entire funnel – by person property, group or cohort, or event property”

“Actions are retroactive, meaning they also apply to past events, not only events that happen after the action was created.”

“Session replay records what real users do in your product and plays it back like a DVR, with a synced DevTools panel showing console logs, network requests, and errors at the exact moment they happened. Because PostHog already captures your events, every replay is enriched with the person, their properties, and the feature flags they had, so you can jump from a funnel drop-off or an exception straight to the session behind it.”

“PostHog is free to use and each product has a generous free monthly allowance (1M events for analytics, 5K session replays, 1M feature flag requests, and more). There is no minimum spend or annual contracts needed and you can set billing limits so you're never surprised.”

“Product analytics Aggregate trends, funnels, retention, and stickiness by group Track how many companies completed onboarding”

“Group analytics aggregates events by entities like organizations or companies instead of individual users. This is useful when you need to track behavior at the company, team, or project level.”

“We also offer PostHog Cloud EU – a managed version of PostHog with servers hosted in Frankfurt, ensuring user data never leaves EU jurisdiction.”

“We don't publish CVEs for PostHog. A CVE names the affected version(s) and the release that fixes them, but PostHog doesn't have versions: self-hosted deployments are officially unsupported, and every change, including security fixes, ships continuously from master to PostHog Cloud and to the latest Docker image. We recommend running your instance the way we run PostHog Cloud: always on the latest image.”

“Experiments let you test a change against a control and find out whether it actually worked. You define variants, pick the metrics you care about, and PostHog randomizes your users, tracks their exposures, and runs the statistics – Bayesian or frequentist – so you get a real answer instead of a hunch.”

“Because experiments run on the same events and feature flags you already have in PostHog, you don't need new instrumentation to measure a result. Any event, data warehouse table, or funnel you've already built can become an experiment metric, and every variant is linked to the session replays of the people who saw it.”

“Surveys collect qualitative feedback from your users – NPS, product-market fit, churn reasons, or plain open text – and put it next to everything else PostHog already knows about them. Ask the right people at the right moment with targeting built on the same events, properties, cohorts, and feature flags you use everywhere else.”

“PostHog is open-source and freely available for anyone to host themselves. We offer a free Docker Compose deployment under an MIT license. Essentially, self-hosting PostHog means you run or purchase your own infrastructure, manage deployments, choose your own URLs to expose it on, and deal with any scaling issues yourself.”

“Autocapture works out of the box on web. Add an SDK for mobile or backend when you need custom events.”

“Write SQL queries directly against your data without a separate data warehouse”

“PostHog has per-product usage-based pricing. This means you only pay for what you use, such as events captured, sessions recorded, and flags requested.”

“Events are retained for 1 year on free plans and 2 years on pay-as-you-go plans. Platform packages let you set a custom retention policy to keep events for longer: up to 3 years on Boost, 5 years on Scale, and 7 years on Enterprise. For more information on data retention, see the events data retention docs.”

“On the pay-as-you-go plan, we charge based on usage for everything above the free allowance. On the free plan, any additional events are permanently dropped and feature flags will return a default quota limited response.”

“Once you subscribe to group analytics, billing applies to all identified events in your project, not just events with group properties attached. This is because group analytics enables infrastructure that processes all identified events to support group-level analysis.”
