Importance of open source
Session replay touches product behavior, user privacy, and debugging workflows. Source visibility makes those boundaries easier to inspect.
Read the practical answer first, then inspect the product without creating an account.
The short answer
Replay tools run inside your product and observe behavior that users rarely think about explicitly. That does not make replay bad, but it does mean teams should know what is captured, masked, stored, and shared.
Open source gives technical teams a way to inspect that boundary: SDK behavior, redaction rules, payload shape, deployment options, retention, and the path to self-hosting if requirements change.
Rejourney pairs that source-visible base with a practical workspace for replay, journeys, heatmaps, crashes, ANRs, API context, and analytics.
From idea to evidence
1. Source visibility
Replay tools run inside your product and observe behavior that users rarely think about explicitly. That does not make replay bad, but it does mean teams should know what is captured, masked, stored, and shared.
2. Self-hosting
Open source gives technical teams a way to inspect that boundary: SDK behavior, redaction rules, payload shape, deployment options, retention, and the path to self-hosting if requirements change.
3. Data control

Understand what replay records, what it explains, and where it falls short.
Learn when to start with session evidence instead of another aggregate chart.
Turn observed product behavior into a bounded investigation.
Replay data can include sensitive product behavior. Open source gives teams more auditability, deployment flexibility, and confidence in how the observability stack works.
Yes. Rejourney is open source and includes self-hosting documentation for teams that want more control over their analytics and replay infrastructure.
Yes. Rejourney is designed to keep replay, analytics, heatmaps, journeys, and stability context approachable while still giving technical teams source visibility.
