This is the most common interpretation of "portable replays"—getting a video file (like MP4 or WebM) that can be emailed, archived, or opened in standard video players.
"PostHog Session Replay Portable" means the ability to take the raw event stream of a user session, move it outside of PostHog’s UI, and process it using your own tools (SQL, Python, Spark) without performance penalties or legal friction.
However, the concept of portability is not without its technical challenges. A session replay is complex, consisting of a DOM snapshot and a stream of incremental updates. Making this data lightweight enough to be easily moved and stored, while still being high-fidelity enough to reproduce the user’s experience, is a difficult engineering feat. PostHog addresses this through efficient compression and a decoupled architecture, where the ingestion pipeline and the storage layer can scale independently.
By default, session replays are stored in PostHog’s cloud (or your self-hosted instance) and viewed in their UI. Making them "portable" implies:
Here’s a concise piece on , framed for a technical audience evaluating its portability and practicality.
