PostHog review (2026): features, pros and cons, pricing
Developer-oriented product analytics and experimentation suite with usage billing and separate allowances for each product.

Pros
- Reviewers value the combined analytics and replay workflows.
Cons
- Reviewers describe a steep initial setup for less technical users.

PostHog pricing
PostHog charges per event for product analytics. The Free plan includes 1 million analytics events per month, and the allowance renews monthly. Beyond it, billing is pay as you go. Billing is per product, so analytics, session replay (5,000 free recordings monthly) and feature flags each carry their own usage. The pricing page does not publish a per-seat price, annual discount, add-on prices or renewal terms. Confirm package and quote details for anything not listed, because SSO, audit logs and custom roles come through platform packages.
| Plan | Price | Unit | Notes |
|---|---|---|---|
| Free | $0 | month | 1 million analytics events per month |
| Usage based | Usage based | event | Free allowance renews monthly |
Paid quote required for unlisted tiers; confirm billing and package before signing. Feature flags: first 1 million flag requests per month free; experiments are billed with flags.

What PostHog really costs
PostHog publishes a starting price but few details about how the bill grows, so the real cost depends on the quote. Use the questions below to turn a sales conversation into a number you can compare.
Questions to ask about price
- Is there a minimum number of seats or a minimum annual spend?
- What is the discount for annual billing, and can we start monthly?
- Which features we need sit in add-ons or a higher plan, and what do they cost?
- How much can the price rise at renewal, and is the increase capped in the contract?
- Are there one-time costs for implementation, onboarding or data migration?
Is PostHog worth the price?
PostHog is good value for engineering-led SaaS teams that want analytics, flags, experiments and replay in one place and are happy to watch usage per product. Starting at $0 with separate free tiers keeps early costs low. It gets awkward for buyers who want a single fixed enterprise bill, or who want no technical setup, since the tool assumes developers own instrumentation.
Worth it if
- Engineering-led SaaS teams owning instrumentation.
- Teams that want analytics beside flags and replay.
- Product engineering teams with event instrumentation.
- Startups seeking a generous usage-based free tier.
Look elsewhere if
- Teams expecting a single fixed enterprise bill.
- Buyers who want no technical setup.
- Marketing teams seeking a pure visual CRO suite.
- Teams that cannot forecast high-volume flag requests.
Pricing details most reviews leave out
- Separate free tiers for analytics and session replay.
- Cohorts can filter funnels and feature flags.
- Experiments share the feature flag billing meter.
- PostHog lets users set billing limits per product.
Our verdict on PostHog
PostHog sells product analytics, feature flags, experiments and session replay as separate products with separate allowances, and bills each by usage. Product analytics includes 1 million events per month free, and session replay has its own free tier of 5,000 recordings. Above those allowances you pay as you go, so a team can start at $0 and add products one at a time.
The catch is that there is no single fixed bill. Each product meters separately, and the pricing page lists only a Free plan and a usage-based tier, with no per-seat price, annual discount or minimum. Engineering-led teams that own their instrumentation will manage this well. Teams that want one predictable enterprise number will find the model harder to forecast.
