PostHog

What it is for

PostHog is a product-analytics desk: you capture events, ask them as an Insight, and you can start Cloud at $0 (1M events, 5K replays, no card) or self-host. Use it when the job is product events you start at $0, not when you need a $20 chat seat.

What makes it unique: the cover is the official PostHog SQL Insight (events table, Think, results) from the insights docs — not a pricing card. The editor itself is ops of Insights. Trends / Funnels / Retention / SQL are options on this ask.

Key features

• Insights — an ask on captured events (insights; pricing Analytics 1M events). One ask. Trends / Funnels / Retention / SQL are options on this. The cover SQL table is ops. The SDK is install.
• Session replay — a recording you scrub (pricing 5K recordings). A movie, not an Insight chart. Replay Vision credits sit on this SKU.
• Feature flags — an on/off (or multivariate) gate (pricing 1M requests). A gate, not a chart. Experiments are billed with flags, not a second meter — do not count them as a fifth surface.
• Surveys — an in-app or link questionnaire (pricing 1,500 responses). A question you ask a person, not an event you chart.
• Error tracking — exceptions you group (pricing 100K exceptions). A crash, not a flag. Sources / destinations / AI observability are separate meters on the same bill.

Events, recordings, flag requests, survey responses, and exceptions are the Cloud meters. Free is $0 with those monthly allowances. Set a billing limit if you expect to go over — do not invent a per-event dollar the calculator did not print as a fixed card.

Who it's for

Best fit: product / eng teams who will stay on Cloud Free $0 (1M events, 5K replays, 1M flag requests, 1,500 surveys, 100K exceptions, 1 project, no card) while they ask a first Insight, then raise a billing limit when a launch week would freeze at the cap — or self-host when they will run the stack.

Pricing

Verified 2026-10-22 (Asia/Shanghai) from posthog.com/pricing. Cloud is usage per product. Free is $0 and is not a trial. Self-host of the public app is $0.

• Free (Cloud) — $0/month. No card. Not a trial. Unlimited team members. 1 project. 1-year event retention. Community support. Printed monthly allowances: Analytics 1M events; Session replay 5K recordings; Feature flags 1M requests; Error tracking 100K exceptions; Surveys 1,500 responses; Sources 1M rows; Destinations 10K events + 1M rows; AI observability 100K events. Usage can stop at the free cap unless you set a billing limit.
• Pay-as-you-go — usage above each product’s free allowance. The estimate we fetched started at $0 with those products on the free blocks. Confirm the live calculator for overage — do not invent a per-event rate.
• Logs retention — default 14 days; extra months print $0.05/GB stored per extra month.
• Setup call — $80 for 30 minutes with a PostHog expert (as printed).
• Self-host — $0 for the public app. You run it. Cloud US (Virginia) or EU (Frankfurt) on the hosted path.

Confirm checkout; taxes follow your location.

Limitations / costs

• Free is 1 project and 1M events. A second project or a viral week is a billing-limit decision, not a second card.
• A product desk, not a privacy pageview tile. For cookie-free pageviews see Plausible or Umami. For session movies without the rest of the OS see OpenReplay.

Alternatives

• Umami — privacy analytics with Hobby $0 / 100k events when you will not run flags, surveys, and replay together.
• Plausible — a one-dashboard pageview tile when you do not want event-level product analytics.
• OpenReplay — session replay you self-host at $0 when the job is a movie, not an Insight.
