PixelHush

Protect API keys, tokens, passwords, database URLs, private keys, and personal data while recording demos, sharing your screen, or presenting live. PixelHush works in two modes: Manual mode lets you hide or reveal sensitive data on the current page at any time. Automatic mode works with the PixelHush macOS desktop app. Free includes automatic protection for supported recording and screen-sharing workflows. Pro adds support for additional apps. A 7-day Pro trial is included. The desktop app tells the extension when to turn protection on and off. See pixelhush.dev for supported apps and plan details. How it works PixelHush scans visible page text, form fields, textareas, and elements that match sensitive selectors. It also watches dynamic DOM updates and programmatic input changes, so protection keeps working in modern web apps and dashboards.
