ResourceSwap von Charles Strahan

Redirect production website resources to your local dev server — test local
code changes against a live production site without touching the server.

ResourceSwap intercepts network requests for scripts, stylesheets, images,
fonts, XHR/fetch, and media, and redirects them to a URL of your choice (e.g.
your localhost dev server). Point a live production page at your in-progress
local build to debug and iterate against real data and real conditions.

Features

• Redirect any resource type: scripts, stylesheets, XHR/fetch, images, fonts, media
• Per-rule enable/disable toggles and a global on/off switch
• Automatic CORS header injection for localhost responses
• Import and export your rules as JSON
• Dark mode support
• Pop-out window mode (handy in Firefox, where popups close on blur)

Everything runs locally. ResourceSwap collects no data and sends nothing to any
server.
