Overview
Professional sensitive data redaction for live demos.
DemoMask is an automated privacy layer designed for sales engineers, developers, and founders. It seamlessly detects and redacts sensitive information on any webpage, allowing you to deliver live demos without worrying about accidentally exposing customer emails, personal data, or production secrets. BUILT FOR PERFORMANCE DemoMask operates as a zero-latency filter between the DOM and your display. By leveraging modern browser APIs, it redacts sensitive patterns before the content is painted to the screen. This ensures a professional, flicker-free experience without the visual glitches common in legacy masking tools. KEY CAPABILITIES ⚡ Zero-Latency Engine: Instant redaction upon page load ensures data is never visible, even for a millisecond. 🔒 100% Local Execution: Security by design. All processing occurs strictly within your browser. No data is collected, stored, or transmitted—ever. ⚛️ SPA & Shadow DOM Support: Fully compatible with modern frameworks (React, Vue, Angular) and dynamic content. 🧠 Context-Aware Detection: Goes beyond simple patterns to identify labeled secrets (e.g., db_password: "...") intelligently. 🖱️ Manual Override: Simply hold Alt + Click on any element to instantly mask or reveal it during your presentation. AUTOMATED PROTECTION SUITE DemoMask actively monitors and shields: Identity: Email addresses, international phone numbers, and IBANs. Infrastructure: IPv4 addresses, API keys (Stripe, AWS, GitHub), and access tokens. Finance: Credit card numbers (verified via Luhn algorithm). Custom Filtering: Add project-specific keywords (e.g., "Project X", "Client Name") to your personal blocklist. PRIVACY COMMITMENT Your data belongs to you. DemoMask runs entirely in your local sandbox environment. We do not track usage, analyze content, or communicate with external servers.
