A key factor in the portability of PostHog's replays is its cross-platform nature. It is not restricted to web browsers; rather, it extends across mobile and specialized engineering environments.
With an open architecture built on rrweb and blob storage, PostHog empowers you to , freeing it from the constraints of typical SaaS walled gardens. This ensures that your most valuable insights are never held hostage.
Filter your pipeline to ensure it captures $snapshot events. In PostHog, $snapshot is the core event type containing raw rrweb recording data.
Raw DOM mutations generate massive JSON text arrays. Ensure your export pipeline utilizes Gzip or Brotli compression to minimize storage costs and accelerate playback load times in your custom viewers.
By streaming raw recording events to Amazon S3, Google Cloud Storage, or Snowflake, you bypass PostHog’s standard data retention limits. This allows your data science teams to run custom programmatic analysis on user interaction patterns using their own machine learning models.

PostHog's session replay is a powerhouse for understanding user behavior, but for many engineering and product teams, the real value lies in . Whether you need to move data between environments, share insights with stakeholders without a login, or keep permanent records of critical bugs, understanding how to make PostHog session replay "portable" is essential. 1.

iOS/Android replay is possible but less mature (requires manual instrumentation for screen recording). Web is the primary strength.
: Includes default masking for text inputs and images to protect sensitive user data. Implementation Options posthog-js @posthog/react for easy installation via npm or yarn.
