HtmlWasher – An HTML cleanup tool

In plain words

HtmlWasher is a free online tool that removes scripts, CSS, and unnecessary markup from HTML code. It simplifies messy code in a single click without requiring signup. The tool uses Trafilatura, a Python library that extracts main content from web pages while filtering out boilerplate elements like navigation, ads, and sidebars. It is designed for developers who need to clean HTML for content extraction tasks like building retrieval-augmented generation systems.

From the sources

HTML traces its roots to IBM's GML in 1969, when three engineers named a markup language after their initials. Tim Berners-Lee built on that foundation at CERN in 1989, creating both the web and its markup language. From the browser wars through the XHTML detour, the W3C/WHATWG split, the rise of HTML5, and Flash's demise, the language has been shaped as much by politics as by technical needs. Powered by Trafilatura , a battle-tested Python library that accurately extracts main content from web pages while filtering out boilerplate like navigation, ads, and sidebars. Ideal for building RAG pipelines, training datasets, or content analysis at scale. Did you know? Apify offers a free tier —…from htmlwasher.com

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
