When you watch a replay, the frontend player first queries ClickHouse to get the list of recordings. When you click play, the API retrieves the compressed snapshot data from the blob store, which the browser's JavaScript engine decompresses and plays back [12†L23-L25].

This method ensures that the moment a session is recorded, a portable copy lives in your cloud storage.

Many regulated industries (Finance, Healthcare) require that user data—including screen recordings—must reside on servers within a specific geographic region or on-premise infrastructure. With "portable" replays, you can host PostHog in your own VPC, ensuring those session recordings never touch a third-party server. from posthog import Posthog import json It's important

PostHog features built-in data pipelines (formerly known as apps or plugins) designed to export events automatically.
