DevSwitch - Localhost Overrides

Why Use DevSwitch • Local-only: Rules are stored in chrome.storage.local. No login, no cloud sync. • MV3-native: Uses declarative rules (no request interception / body inspection). • Low overhead: Redirects and header modifications are handled by the browser’s declarative networking layer.  • Dev-focused scope: Redirect + basic header overrides + fast enable/disable. Features • Regex / pattern redirection: map https://site.com/app.js → http://localhost:3000/app.js • Header rules (basic): set / append / remove request or response headers (where supported by DNR) • Global kill switch: instantly disable all rules • Import / export: back up and share rule sets as JSON
