Your first 1 million events, 5k recordings, 1M flag requests, 100k exceptions, and 1500 survey responses are free every month, after which you pay based on usage. ### Self-hosting the open-source hobby deploy (Advanced) If you want to self-host PostHog, you can deploy a hobby instance in one line on Linux with Docker (recommended 4GB memory): ```bash /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/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](https://posthog.com/docs/migrate/migrate-to-cloud). We _do not_ provide customer support or offer guarantees for open source deployments. See our [self-hosting docs](https://posthog.com/docs/self-host), [troubleshooting guide](https://posthog.com/docs/self-host/deploy/troubleshooting), and [disclaimer](https://posthog.com/docs/self-host/open-source/disclaimer) for more info. ## Setting up PostHog Once you've got a PostHog instance, you can set it up by installing our [JavaScript web snippet](https://posthog.com/docs/getting-started/install?tab=snippet), one of [our SDKs](https://posthog.com/docs/getting-started/install?tab=sdks), or by [using our API](https://posthog.com/docs/getting-started/install?tab=api).
