The fastest and most reliable way to get started with PostHog is signing up for free toPostHog CloudorPostHog Cloud EU.Your first 1 million events (and 5k replays) are free every month, after which you pay based on usage.

Open-source hobby deploy (Advanced)

You can deploy a hobby instance in one line on Linux with Docker (recommended 4GB memory):

/bin/bash -c"$(curl -fsSL https://raw.githubusercontent /posthog/posthog/HEAD/bin/deploy-hobby)"

Open source deployments should scale to approximately 100k events per month, after which we recommend migrating to a PostHog Cloud instance. See ourdocs for more info and limitations.Please note that we do not provide customer support for open source deployments.

Philosophy

Our mission is to increase the number of successful products in the world. To do that, we build product and data tools that help you understand user behavior without losing control of your data.

In our view, third-party analytics tools do not work in a world of cookie deprecation, GDPR, HIPAA, CCPA, and many other four-letter acronyms. PostHog is the alternative to sending all of your customers' personal information and usage data to third parties.

PostHog gives you every tool you need to understand user behavior, develop and test improvements, and release changes to make your product more successful.

PostHog operates in public as much as possible. We detail how we work and our learning on building and running a fast-growing, product-focused startup in ourhandbook.
