Which one is for you
Pick PostHog if
- Fits if you're a startup that wants analytics, replays and flags within the free allowance
- Works for developers who want to go from a broken session to the error behind it
Look elsewhere if
- Skip it if you just want simple visitor counts without learning a whole toolkit
- Pricey if you need SSO or a HIPAA BAA, which take Boost at $250 a month on top of usage; SAML takes Scale at $750
- Not for you if you want a fixed monthly bill, as everything past the free allowance is metered
- Tight if you stay free, with 1 project, recordings kept a month and events dropped past the limits
- Watch out: self-hosted PostHog is officially unsupported, with no tagged releases or paid support
Pick Statsig if
- Fits if you ship features behind flags and want results in the same tool
- Works for small teams that want unlimited seats on a free plan
Look elsewhere if
- Tight if you want CUPED or holdouts, which are Pro
- Pricey if you go past 5M events, at $0.05 per 1K events on Pro
- Watch out: SSO, role-based access and warehouse deployment are Enterprise only
- Watch out: unlimited retention isn't on the free plan
- Not for you if you want a quick setup, because SDKs go into your product first
How we grade them
| 3.2GPAPostHogVery good | 3.0GPAStatsigVery good | |
|---|---|---|
| Value for money | AA site with 10,000 visitors a month fits in the free 1M events and 5,000 recordings, so the figure is $0. There's no base fee after that, just usage from $0.00005 an event. Boost, at $250 a month, is only for SSO, HIPAA and more projects. | AFree for 2M events a month with unlimited seats, which covers most small teams. Pro is $150 for 5M events. |
| Free plan and trial | BNo card and no time limit: 1M events, 5,000 recordings, 1M flag requests and 1,500 survey responses every month, with unlimited members. Usage stops at the limit, so no surprise bill. You get 1 project, and recordings are kept a month. | B2M events, unlimited flag checks and 50,000 replays a month, free. Real use, though the advanced stats aren't included. |
| Features | AAnalytics, web analytics, replays, flags, A/B tests, surveys, error tracking, logs and a data warehouse with pipelines in and out. Graded against Amplitude, Mixpanel and Heap, it covers the whole job, and none of them bundles errors, logs and a warehouse too. | BExperiments, flags, product analytics, replay and SDKs. Nothing in the core job is missing. |
| Ease of use | CNo rating on record. The cloud version is a snippet and a sign-up, but there are a lot of products to learn and events to plan. The free self-hosted version is a Docker deploy PostHog doesn't officially support, which is a developer's job. | CNo rating read. You add SDKs and define metrics first. |
| Platforms and integrations | BWeb only, so it can't reach an A. It pulls data in from Stripe, HubSpot, Salesforce and Postgres, sends events out to Braze, Klaviyo and others, and works with Snowflake, BigQuery and Zendesk. | BWeb with SDKs, and Segment, Amplitude, Mixpanel, Datadog, Slack and Jira links. |
| Best for | a whole product toolkit on one free allowance | feature flags and experiments in one place |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
