tinyhtml5
HTML parser based on the WHATWG HTML specification
Decision gist · record as of 2026-08-14
Yes, if you need to parse HTML5 and want a lightweight, dependency-light solution. The package is actively maintained, has no known vulnerabilities, installs with low friction, and carries a permissive MIT license. It's well-suited for scripting and data extraction tasks where a full HTML rendering engine is overkill. Start with it if your use case is parsing, not rendering.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Low friction: pure Python wheel with a single lightweight dependency (webencodings).
- Actively maintained with recent commits; marked Production/Stable and tested on both CPython and PyPy.

What it is and what it does
tinyhtml5 is a minimal HTML5 parser that reads HTML documents—even broken or non-standard ones—and converts them into an ElementTree structure. It's a simplified fork of html5lib, designed to be lightweight while still handling real-world HTML that doesn't conform to strict standards. The parser depends only on webencodings for character encoding support.
You would use this when you need to extract or manipulate HTML content programmatically but don't want the overhead of a full browser engine or a large dependency tree. It's suitable for web scraping, HTML analysis, or any task where you need to parse HTML into a tree structure that Python's standard ElementTree tools can work with.
Use it for
- Web scraping: parse HTML from web pages and extract data using XPath or tree traversal.
- HTML validation and cleanup: transform malformed HTML into a normalized ElementTree for analysis.
- Content extraction: build tools that read and process HTML documents without a browser.
- HTML-to-XML conversion: convert HTML into a structured tree format for downstream processing.
