What is Trafilatura Core?
Trafilatura Core cleans HTML: paste a raw page into the playground and get cleaned HTML back — boilerplate like navigation, ads, sidebars, and footers stripped, main content kept. A page-type classifier routes extraction so articles, forums, product pages, and listings each get a matching strategy. The engine is a free and open-source hybrid Rust + TypeScript port of Trafilatura, and it runs offline — HTML in, cleaned HTML out, never fetching the network. The playground also generates the npm CLI command or TypeScript library code that reproduces your settings.
The name is literal: Trafilatura Core is deliberately restricted to core functionality — HTML in, cleaned HTML out. Conversion to Markdown or other formats is left to other libraries that do it better.
To crawl and extract live websites online, try Contextractor — it is built on this engine and adds crawling and Markdown, text, and JSON output.
