PostHog
PostHog is an open-source product analytics platform: funnels, retention and web analytics, with session replay, feature flags, A/B tests, surveys and error tracking on the same events.
It suits founders who build the product themselves, or with an AI coding agent, and want one tool where an error, a replay and a drop in the funnel point to the same user.
Each product has a free amount every month, 1 million analytics events among them; above it you pay per use with no base fee or seat charge, as checked on 30 October 2026.

- What it does
- Product analytics, session replay, feature flags, experiments and error tracking in one tool, priced by use with a free amount of each every month.
- Our take
- Founders who build the product themselves, or with Claude Code, Cursor or Codex, and want analytics, replays, flags and errors in one place. The setup wizard installs PostHog from one command, and its MCP server lets your agent query funnels, ship a feature flag or read a stack trace from the editor.
- Pricing
- FreemiumThe free plan needs no card and resets each month: 1 million analytics events, 5,000 web and 2,500 mobile session recordings, 1 million feature flag requests, 1,500 survey responses and 100,000 errors, for 1 project with 1 year of data. The paid plan, pay as you go, is $0 a month: the same free amounts, then a price per unit that falls with volume, with 6 projects and 7 years of data. The next million analytics events cost $0.00005 each, $50 in all, and a recording past 5,000 costs half a cent, as checked on 30 October 2026. Events tied to a signed-in person cost more, and PostHog says anonymous ones can be up to 4x cheaper. There is no charge per seat, and you can set a dollar limit on each product, after which PostHog stops taking that product's data for the month. Boost, Scale and Enterprise packages ($250, $750 and $2,000 a month) add team features. Companies under 2 years old with less than $5M raised can apply for $50,000 in credits for 12 months.
The IndieHacked breakdown
What it does
PostHog collects events from your website, app or backend and builds funnels, retention, user paths and trends from them, with a web analytics dashboard of visitors, pageviews and traffic sources on the same data. Session replay, feature flags, A/B tests, surveys, error tracking, logs and AI observability run on those events too, so an error arrives with the affected user's replay, and a SQL editor and data warehouse let you query Stripe, HubSpot or Postgres data next to it.
Setup is one command, npx @posthog/wizard, which detects the framework and installs the SDK. The MCP server is free to connect and works with Claude Code, Cursor, Codex, VS Code and other MCP clients. PostHog Cloud runs in the US or in the EU, with servers in Frankfurt, and the code is open source under the MIT license; a self-hosted Docker version is free but unsupported.
Who it suits
Founders who write the product, or have an agent write it, and want one place to see what users do and what broke. PostHog says it is built for engineers and product teams; its comparison with Mixpanel says more than 90% of companies use it for free. The free plan needs no card, so tracking can go in before the first user arrives.
It fits a founder who wants a usage bill instead of a plan. There are no seats to buy, so a cofounder or contractor joins free, and a dollar limit per product caps the month. A company under 2 years old with less than $5M raised can apply for $50,000 in credits for 12 months.
Not the right fit for
Developers who need deep stack traces, distributed tracing and mature error triage, or crash reports from a native mobile app. PostHog's own comparison says Sentry's tracing and monitoring are more mature and points mobile-focused teams there; Sentry is reviewed here.
Founders handing analytics to a product manager or marketer who will not write SQL or read an event schema. PostHog's own comparison recommends Mixpanel, reviewed here, to product management teams for an interface built for non-technical users.
