Description
Edit HTTP headers with profiles, plus the cookies and localStorage of the active site. All local, no accounts or servers. DevSwitch brings the everyday web-testing controls into one Chrome popup: HTTP request header profiles, a cookie editor and a localStorage editor for the site you have open. HEADERS • Create profiles for different scenarios (staging, QA, feature flags…) and switch between them in one click. • Add request headers and turn each one on or off individually. • A global switch turns every header change off at once, and the toolbar badge shows which profile is active. • Invalid or duplicated header names are flagged instead of failing silently. COOKIES • View, search, create, edit and delete the cookies of the active site, with every attribute: domain, path, expiration, Secure, HttpOnly and SameSite. • Switch a cookie off to remove it from the browser while keeping a local copy, then switch it back on to restore it. If the site recreates it in the meantime, DevSwitch tells you. STORAGE • View, search, create, edit and delete the localStorage items of the active site. • Switch items off and on, just like cookies. IMPORT & EXPORT • Import and export header profiles, cookies and storage items as JSON. PRIVACY • No account, no backend, no analytics, no remote code. • Everything is stored on your device with chrome.storage.local and is never synced. • The headers and cookies you configure reach the sites you visit only as part of the browser's normal requests. Works on http and https pages; Chrome's internal pages can't be modified. Available in English, Spanish and Portuguese, with light and dark themes that follow your system.
