DevLens URL Params

Live URL query parameter editor, hash route inspector & origin presets for developers.

Inspect, edit and share URL query strings without leaving the page. DevLens URL Params opens in Chrome’s side panel and breaks the current tab’s address into its parts: origin, path, query parameters and hash route (including hash routes with their own query, like #/order/42?tab=items). Change anything, then apply it to the tab or open it in a new one. WHAT YOU CAN DO • See every query parameter as an editable row: key, value and an on/off toggle • Add, remove, rename and sort parameters, or switch one off without deleting it • Follow the active tab: the panel updates as you navigate or switch tabs • Apply the edited URL to the current tab, or open it in a new tab • Copy the result as a URL, as JSON, or as URLSearchParams JavaScript code • Save presets per site (for example debug=true&role=admin) and re-apply them in one click • Right-click any link or selected URL and choose “Inspect URL params in DevLens” • Light, dark and high-contrast themes that follow your system setting PRIVATE BY DESIGN • Runs entirely in your browser. No accounts, no analytics, no network requests • Reads only the tab’s address, never the page content • Presets are stored locally on your device Part of DevLens, a set of focused, offline developer tools for Chrome.
