Core Privacy-Safe Co-Browsing & Screen Sharing Capabilities
- Zero-Download DOM Mutation Co-Browsing (`rrweb` + WebSockets) & WebRTC `getDisplayMedia`: Streaming live tab interactions and laser-pointer/cursor highlights with sub-100ms latency without requiring customers to install Zoom or desktop downloads.
- Automatic PII/Password Field Masking: Redacting credit card inputs, SSNs, passwords, and `.co-browse-mask` elements on the client before DOM snapshots or video frames leave the customer's browser.
- Session Replay & Compliance Archival: Recording compressed `rrweb` JSON event streams to S3 for dispute resolution and QA coaching.
Frequently Asked Questions
Why is DOM co-browsing (`rrweb`) better than screen sharing for financial and medical onboarding?
DOM co-browsing only transmits the current web application's sanitized DOM tree—so the support agent can never accidentally see the customer's other browser tabs, desktop notifications, or masked SSN/card inputs.
