Adjust vs PostHog

Adjust is a mobile measurement partner (MMP) founded in Berlin in 2012 and acquired by AppLovin in 2021 in a deal valued at about $1 billion. It tells app marketers which ad networks, campaigns and creatives drove installs, in-app events and revenue, so budget can move to the channels that actually pay back. Its SDK runs inside iOS, Android and Unity apps.

The platform covers attribution and deep linking, Datascape dashboards and cohort reporting, a Fraud Prevention Suite that blocks click spam and fake installs, and support for Apple's SKAdNetwork and AdAttributionKit privacy frameworks. Add-on modules include InSight for incrementality testing with synthetic control groups, Audience Builder, CTV AdVision for connected-TV campaigns and SpendWorks for ad-spend mapping. The free Base plan covers up to 1,500 attributions per month; Core and Enterprise are custom-priced annual contracts.

Adjust suits app publishers, games studios and fintech or ecommerce apps with real paid user-acquisition budgets. AppsFlyer is its biggest rival with a larger partner ecosystem, while Singular leans harder into cost aggregation. Northbeam and Rockerbox, also in our catalog, solve web and DTC attribution rather than app installs, so they are not like-for-like replacements.

In May 2025 Adjust launched Growth Copilot in beta, an AI assistant that answers reporting questions in plain language and, with Pulse, can publish scheduled AI reports. When negotiating, ask for fraud prevention to be bundled, since it is often quoted as a separate add-on.

PostHog is an open-source product analytics platform founded in 2020 by James Hawkins and Tim Glaser and backed by Y Combinator. Its strategy is to give engineering-led companies every product tool in one place: event analytics, web analytics, session replay, feature flags, A/B experiments, surveys, error tracking, a data warehouse and LLM observability, all sharing the same user and event data.

PostHog is built for engineers. Autocapture and SDKs for web, mobile and backend platforms collect events, HogQL gives SQL access to everything, and a CDP pipeline sends data to other tools. Replays connect to events, errors and flags, so you can watch exactly what a flagged cohort experienced. Each product is priced by usage with a generous monthly free allowance, so small teams often pay nothing, and billing limits prevent surprises; optional add-ons add support SLAs, SSO, advanced permissions and longer retention. Cloud hosting is available in the US and EU, and self-hosting is supported for small deployments.

PostHog fits startups and scale-ups that want to replace separate analytics, replay, flag and experimentation vendors with one transparent bill. The interface is dense, and costs need monitoring when many products scale at once. Amplitude and Mixpanel offer deeper analytics experiences for large product organizations, LaunchDarkly is more mature for enterprise feature management, and Plausible or Google Analytics suit marketing teams that only need website traffic reports.
