What it doesAll-in-one product platform: event analytics, session replay, feature flags, experiments, surveys and error tracking.Event-based product analytics for funnels, retention and cohorts, with self-serve reports for the whole team.Lightweight, cookie-free web analytics hosted in the EU, with a one-page dashboard and open-source code.
Best forEarly-stage SaaS that wants funnels, session replays and feature flags in one tool without paying until 1M events a month.SaaS with a PM or growth person who lives in retention and funnel reports and wants them without writing SQL.Landing page or SaaS site that wants visits and conversions without a cookie banner, since it collects no personal data.
Skip it ifYou need a simple LGPD-friendly visit counter: session replay and person profiles call for consent and careful masking of personal data.You expect to pass 1M events soon on a tight budget: 1.5M events already costs $140/month on monthly billing.You need in-app funnels per logged-in user or session replay; it only measures pages and simple events.
SetupA little code. 15 minutes for the snippet; an afternoon to name and send your key events.Needs a developer. A day or two: an hour to install, the rest to plan and send the right events.A little code. About 10 minutes to paste the script and see the first visits.
PricePay as you go: $0.00005/event after 1MGrowth: first 1M events free, then usage-basedFrom $9/month (10K pageviews)
What it costs in practiceA SaaS sending 2M events a month, all from logged-in users: the first 1M is free, the next 1M costs 1M × ($0.00005 + $0.000198) ≈ $248/month. Sent as anonymous events, the same volume is about $50. Rough estimate.A SaaS with 3,000 active users at 500 events each sends 1.5M events a month: $0 for the first 1M, then $140/month on monthly billing or $100/month paid yearly ($1,200/year). Rough estimate.A SaaS site with 7K pageviews and 2K custom events a month stays in the 10K tier: Starter at $9/month, or about $90/year with 2 months free on yearly billing. Two sites push you to Growth at $14/month. Rough estimate.
Free planEvery month: 1M events, 5K session replays, 1M flag requests and 100K exceptions.Up to 1M events/month with unlimited seats.30-day free trial, no card; Community Edition is free to self-host.

Before you build
  • Events tied to a logged-in person cost more than anonymous ones: above the free 1M, an identified event adds $0.000198 on top of the $0.00005 base, about 5x the price.
  • When you hit a billing limit, PostHog stops ingesting and the data sent after that is lost for good, not queued.
  • With cookies on logged-out visitors, PostHog itself says you should show a cookie banner; under LGPD plan the consent flow before launch.
  • Ad blockers can block PostHog, so part of your users never shows up; the official fix is a reverse proxy on your own domain.
  • The free plan keeps data for 1 year and allows 1 project; paid keeps 7 years and allows 6.
  • On the free plan there's no overage bill, but past 1M events in a month you lose access to reports until you upgrade or the month resets.
  • Monthly billing costs about 40% more than yearly: 1.5M events is $140/month paid monthly versus $100/month paid yearly.
  • The web SDK stores data in a cookie by default, so under LGPD you need consent; ad blockers can also block it unless you use a proxy.
  • Custom events count toward your monthly limit just like pageviews, so tracking every click can push you into a higher tier.
  • Over your tier two months in a row, you're asked to upgrade; if you don't within a week, your dashboards are locked until usage drops or you pay more.
  • Strict ad blockers still block the script: Plausible itself expects 5% to 25% of visitors to go uncounted unless you set up a proxy.
  • Funnels and ecommerce revenue are only on Business; Starter covers 1 site and Growth up to 3.
