AngleSharp is a .NET library that parses HTML5, SVG, MathML, XML, and CSS into a fully standards-compliant W3C DOM. It supports querySelector traversal, LINQ over elements, form submission, and browser-like navigation via BrowsingContext.
Use cases
- parse html from web pages in c#
- scrape website data with a real dom api
- extract elements using css selectors like queryselectorall
- parse css stylesheets in .net
- automate form submission and login flows
- build a headless browsing context for testing
When to choose
- you need browser-accurate HTML5 parsing and error correction in .NET
- you want the official W3C DOM API including querySelector in C#
- you need to parse CSS alongside HTML
- you are scraping or testing sites that require form interaction
When to avoid
- you need to execute JavaScript on pages
- you only need simple XPath scraping and prefer HtmlAgilityPack
- you are not working in a .NET language
