Retention policies are necessary for cost management, but they can be a problem for vital data. In PostHog's cloud plans, a 5-year retention period is available only for Enterprise customers; other plans range from 30 days to 1 year [8†L12-L15]. However, by using portable exports, you can archive any recording indefinitely. You can export it as a JSON file for safekeeping in a data lake, then re-import it into PostHog for playback at any time, even after the original recording has expired [8†L20-L23].
Because this entire pipeline runs on your infrastructure, the recording data is inherently portable and under your control. Benefits of Using Portable Session Replay Description Sensitive user data (PII) stays within your VPC. Data Retention You decide how long to keep recordings, not a SaaS plan. Disconnected Environments Operates on internal networks without internet access. Custom Auditing Store recordings alongside internal log systems. How to Set Up Portable (Self-Hosted) Replay
: PostHog allows enterprise/scale users to export raw recording JSON data to parse and render on external players. 🏗️ Strategy 3: The True "Portable" Alternative (rrweb)
is the managed, hands-off option. It handles scaling, uptime, and maintenance for you. For portability, you are dependent on the API and manual export features, which are available to paying users [11†L6-L9]. The cloud service already offers EU and US regions with SOC 2 Type 2 compliance and BAAs for HIPAA, which may satisfy data residency needs for many companies without the operational burden [15†L18-L19][19†L28-L29]. posthog session replay portable
: Your exported data is not a standard video file. The rrweb schema logs events, not pixels. Therefore, you cannot directly export a session replay as an MP4 file. To convert a session to video for broad sharing, you would need a headless browser or a Node.js script that uses the rrweb-player library to replay the JSON snapshot data and encode the resulting output to video.
Portability transforms session replays from an isolated product analytics metric into a company-wide operational asset. By feeding PostHog session replays directly into customer support queues, engineering admin panels, and centralized data warehouses, you eliminate cross-departmental friction. Your teams can stop guessing why errors happen and immediately see the exact user friction points in real time, directly within the tools they use every single day. If you want to build this out, tell me:
: 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. Retention policies are necessary for cost management, but
If you choose PostHog for Session Replay, you aren't buying a tool. You are buying a data source that you happen to watch through a nice UI. When you leave, or when you need to integrate, the data follows you.
If you cannot run a local proxy server (e.g., in a standalone browser-based offline app), you can customize how posthog-js saves events. By utilizing the browser's IndexedDB via custom middleware or by writing a lightweight wrapper around PostHog’s persistence layer, you can store recording chunks locally until the client detects an active internet connection ( navigator.onLine ). Best Practices for Portable Data Privacy
Portability means data travels across networks and systems. To minimize the risk of data leaks, configure masking at the SDK level before data leaves the user's browser. Use PostHog’s built-in masking utilities to obscure inputs, passwords, credit card fields, and specific CSS classes. javascript You can export it as a JSON file
The concept of "portable" session replays in PostHog refers to the platform's ability to move user interaction data beyond the live production dashboard. By enabling teams to export, embed, and share technical session data, PostHog transforms ephemeral behavioral snapshots into durable assets for long-term debugging, compliance, and collaborative analysis. The Mechanics of Portability
In this article, we will deep-dive into what makes "PostHog session replay portable" a game-changer for engineering and product teams. We will explore how to export your data, why self-hosting gives you ultimate control, and how to avoid vendor lock-in forever.
