Show HN: Defuddle, an HTML-to-Markdown alternative to Readability (Score: 154+ in 6 hours)
Link: https://readhacker.news/s/6uW83
Comments: https://readhacker.news/c/6uW83
Defuddle is an open-source JS library I built to parse and extract the main content and metadata from web pages. It can also return the content as Markdown.
I built Defuddle while working on Obsidian Web Clipper[1] (also MIT-licensed) because Mozilla's Readability[2] appears to be mostly abandoned, and didn't work well for many sites.
It's still very much a work in progress, but I thought I'd share it today, in light of the announcement that Mozilla is shutting down Pocket. This library could be helpful to anyone building a read-it-later app.
Defuddle is also available as a CLI:
