RSS Alchemy

About

RSS Alchemy is a website-to-rss converter, like RSSHub, RSS-bridge or Rss.app. Here is the difference:

• Convert arbitrary website to RSS feed using CSS selectors
• Dynamic websites are supported using headless chrome (playwright)
• Cookies¹ (supports scraping private feeds, eg youtube subscriptions)
• Proxy
• Results caching
• Screenshots (primarily for debugging)
• Stateless² (all task parameters are encoded into url, no database needed)
• Distruibuted by design (deploy as many workers as you need)
• Self-hosted; easy to deploy; docker-compose provided
• Relatively small codebase, written in go + typescript

2. Nats KV is used to store cookies permanently, it's required for sites that update cookies on every request, like youtube ↩︎
