## What it is
MyHTML is a fast, fully HTML5-conformant HTML parser written in pure C99 with no external dependencies, using threads for asynchronous parsing and tree building. It offers high- and low-level APIs, DOM manipulation, chunked parsing, and support for 39 character encodings, and is now superseded by the Lexbor project.

## Use cases
- parse html documents in c
- extract data from web pages
- build a dom tree from html5 markup
- scrape websites with a fast native parser
- detect and handle character encodings in html
- parse html fragments or streaming chunks

## When to choose
- you need a dependency-free, pure C HTML5 parser with threaded performance
- you must parse HTML in a C or C++ project with bindings for other languages
- you need strict HTML5 spec conformance validated by html5lib-tests

## When to avoid
- starting a new project — use Lexbor instead, as the author recommends
- you need CSS selector support or rendering features
- you want a parser in a higher-level language without writing bindings

## Facets
- artifact type: library
