Replay Portable | Posthog Session

: Security teams working in isolated networks or restricted intranets cannot stream cloud media player links. Portable files can be moved securely via local media or internal file-shares.

The ability to download complete individual session data into highly compressed JSON files, which can later be re-uploaded or played back in detached environments.

PostHog Session Replay is a user-recording feature that captures visitor interactions (clicks, mouse movements, scrolls, form inputs, and DOM changes) so teams can replay real user sessions to reproduce bugs, understand workflows, and improve UX. Making Session Replay portable focuses on easy export, lightweight embedding, privacy-preserving portability, and compatibility across environments. posthog session replay portable

Running PostHog (including replay storage) requires managing ClickHouse, Kafka, and Redis. Their Helm chart and Docker Compose help, but it’s heavier than a SaaS-only tool.

Bullet points of every tiny change (mutations, mouse moves, touches) that occurred after the baseline. : Security teams working in isolated networks or

A background daemon checks for internet connectivity. When an active connection is detected, it flushes the stored SQLite rows back to PostHog Cloud sequentially. 3. Raw rrweb Serialization (The Ultra-Lightweight Pattern)

Running session replay on a local machine during User Acceptance Testing (UAT) allows engineers to catch edge-case visual bugs, state management failures, and race conditions before code ever hits a staging server. 3. Mobile and Field Testing

While PostHog is an exceptional platform for capturing session recordings, feature flags, and heatmaps, true operational efficiency happens when you make that data portable.
