Adel Dev Tools

Chrome developer tools for storage, cookies, APIs, CORS, Pixel Perfect, tabs, TOTP, location testing, JWTs and backups.

Adel Dev Tools is a browser developer toolkit for inspecting site data, testing page behavior, comparing interfaces, and managing repeatable QA workflows from one Chrome extension. BROWSER STORAGE • Inspect and edit local storage, session storage, cookies, Cache Storage, and IndexedDB. • Search, add, update, delete, import, and export values. • Format JSON before saving changes to the selected website. NETWORK AND PAGE TESTING • Send API requests and inspect status codes, headers, timing, and response bodies. • Apply temporary, site-scoped CORS rules for development. • Switch the user agent and test geolocation with a place, preset, or exact coordinates. • Review page performance, responsive layouts, accessibility signals, CSS, screenshots, and debugging overlays. VISUAL QA • Place reference images over a page with Pixel Perfect. • Adjust layers, opacity, scale, position, rotation, and blend mode. • Use grids, guides, rulers, profiles, and pixel-match comparison. AUTHENTICATOR • Generate TOTP two-factor authentication codes locally. • Import standard otpauth links and multi-account Google Authenticator QR exports. • Organize favorites, temporary burner accounts, regular accounts, and archives. • Optionally sync one encrypted authenticator list with the companion web app through your private Google Drive app-data folder. BROWSER WORKFLOWS • Organize tabs, Chrome tab groups, and saved browsing sessions. • Decode and save JWTs; generate mock data; encode, hash, convert, encrypt, and format test values. • Clear selected browser data for the current site or, after confirmation, across sites. • Create encrypted local backups or optional scheduled Google Drive backups. The interface supports light, dark, and system themes. Tools run in the extension; network access is used only for actions such as API tests, location search, release data, and optional Google Drive sync or backup.
