> Open-source product analytics with replays, flags and surveys

PostHog is a set of product tools under one sign-up: product and web analytics, session replay, feature flags and experiments, surveys, error tracking, logs and a data warehouse. Each product has a free monthly allowance that resets, and usage above it is billed per event, recording or request. The code is open source under the MIT license, and a free Docker deployment can be run on your own server.

## Ways to pay less

- **$50,000 in credits for early-stage startups** (Startups): Companies under 2 years old that have raised less than $5M get $50,000 of PostHog credit for 12 months, plus partner perks. A company email domain is required. Source: https://posthog.com/startups
- **Discount for nonprofits** (Nonprofit): PostHog says it gives nonprofits a discount in most cases: create an account, then contact sales with details of the organization. Source: https://posthog.com/pricing

## Key features

- **Product and web analytics:** Funnels, trends, retention, user paths and a web analytics dashboard, built from events. The first 1M events a month are free.
- **Session replay:** Recordings of real visits to see where people get stuck, linked to funnels and errors. 5,000 recordings a month are free; recordings are kept 90 days on pay-as-you-go.
- **Feature flags and experiments:** Roll features out to chosen users and run A/B tests, billed together by flag requests, with 1M requests free each month.
- **Surveys:** In-app surveys with 1,500 free responses a month, and white-labeled surveys on the Boost package.
- **Error tracking and logs:** Captures exceptions (100K free a month) and ingests logs (10 GB free), so you can go from a replay to the error behind it.
- **Data warehouse and pipelines:** Syncs data in from Stripe, HubSpot, Salesforce, Postgres and others, and sends events out to tools such as Braze and Klaviyo.

## Good for

- Startups and developers who want many product tools under one bill
- Teams that want to cap spend with a billing limit per product
- Companies that prefer open-source software they can host themselves

## Worth knowing

- Usage is metered per product, so the monthly bill moves with traffic; billing limits can be set for each product to cap it.
- SSO enforcement, a HIPAA BAA and unlimited projects need the $250-a-month Boost package on top of usage; SAML sign-in needs Scale at $750.
- The free plan keeps recordings for 1 month and data for 1 year, allows 1 project, and drops events past its limits.
- Self-hosted PostHog is officially unsupported and has no tagged releases; PostHog recommends always running the latest image.

## ToolGPA grades

**GPA: 3.2 out of 4**, graded Oct 18, 2026. PostHog bundles product analytics, web analytics, replays, feature flags, experiments, surveys, error tracking and a data warehouse under one sign-up. Each has a free monthly allowance, and plenty of small products never pass it. The flip side is a bill that moves with your traffic once you do, though you can cap spend product by product.

- **Value for money: A.** A 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.
- **Free plan and trial: B.** No 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.
- **Features: A.** Analytics, 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.
- **Ease of use: C.** No 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.
- **Platforms and integrations: B.** Web 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.

## Keep it, or make your own?

**Keep it.** The plain part of PostHog you could make: surveys. What surrounds it you could not. The 6 things listed below take a company, not a weekend. It is one of the better ones too: its GPA of 3.2 is higher than 11 of the 13 other website and product analytics tools we grade. PostHog is open source, so there is a third way: take its code and run it yourself.

- You could make: Surveys: an app builder makes this well.
- You could not: A tracking script and a database that counts every visit.
- You could not: Recordings of what each visitor did on your pages.
- You could not: Splitting visitors between versions and telling you which won.
- You could not: It plugs into other products, Stripe, HubSpot and Salesforce among them.
- You could not: AI features, unless you pay a model provider for each request yourself.
- You could not: The depth: we grade its features A, which means it covers the whole job.
