Device It
ChatGPT pluginMake an offline-ready preview
Create an offline-ready local preview of your web app. Device It takes a finished static build and prepares a separate preview with app icons, a web app manifest and a QR code. Browser checks verify that the selected app shell still opens without a connection, with a report and screenshot to review. Your original build stays untouched. Offline coverage applies to selected static assets, not login, backend calls or every app feature. QR reach depends on the preview address; phone installation and hosting are not included. Requires a local coding assistant, Node.js 22+, installed package dependencies and Playwright Chromium.
