Posthog Session Replay Portable 〈Top 20 Instant〉

Unlike tools that force you to stream replays only to their cloud, PostHog’s open-source core lets you self-host the entire stack. Your session replays (DOM snapshots, console logs, network activity) live on . No vendor lock-in: migrate them to another system, archive them in your data lake, or delete them programmatically—all with full control.

By adopting a portable session replay strategy today, you future-proof your product analytics. You ensure that your user insights remain a strategic asset you control, not a subscription you rent.

To watch the sessions, you import these JSON files into a custom local HTML page running rrweb-player , or build an ingestion script that uploads them to a central PostHog instance later using the PostHog Capture API.

If you only need the recordings without the overhead of the PostHog ingestion engine, you can bypass the PostHog backend entirely during collection.

You deploy a lightweight Go, Node.js, or Nginx proxy directly on the user's local machine alongside your application. The posthog-js SDK points to this local proxy ( http://localhost:3000 ).

Here’s a concise piece on , framed for a technical audience evaluating its portability and practicality. By adopting a portable session replay strategy today,

In a self-hosted PostHog environment, this data is sent to your own instance of PostHog-JS. A Rust-based capture service handles the ingestion, validated by rust/capture/src/v0_endpoint.rs , and publishes it to a session_recording_snapshot_item_events topic (usually in Kafka).

Every piece of data visualized in the PostHog UI is accessible via a standardized REST API. You can programmatically query the /api/projects/project_id/session_recordings endpoint to fetch recording metadata, state data, and raw rrweb payloads. This programmatic access means you can build custom internal viewing tools or migrate snapshots into separate business intelligence (BI) systems without relying on the PostHog interface.
