No backend: this app fetches feeds through your Cloudflare Worker (a tiny CORS-friendly proxy). Set the Worker URL below (must end with ?url=) and the app will read RSS/Atom safely in the browser.
Must end with ?url=. Recommended: your Worker URL, e.g. https://red-wood-fe7e.fallenangelbg.workers.dev/?url=. You can change this anytime.
