htmltools
Tools for HTML generation and output.
Decision gist · record as of 2026-08-14
Yes. htmltools is a lightweight, actively maintained library with no known vulnerabilities, permissive licensing, and minimal dependencies. It fills a clear niche for programmatic HTML generation in Python. Install it if you need to build HTML dynamically from code rather than using string templates or a heavier templating framework.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Low install friction with only two lightweight runtime dependencies (typing-extensions and packaging).
- Active maintenance with a recent release 85 days ago and ongoing repository activity.

What it is and what it does
htmltools is a Python library for building HTML documents and fragments programmatically. It provides a set of functions and classes to construct HTML elements, nest them, set attributes, and render them to strings. The library is designed for developers who need to generate HTML dynamically from Python code—whether for web applications, templating systems, or documentation generation.
The package depends only on typing-extensions and packaging, keeping its footprint minimal. It supports modern Python versions from 3.10 onward and is actively maintained. The library fits into workflows where HTML generation is a core task but a full templating engine may be overkill, making it suitable for programmatic HTML construction in frameworks, data reporting tools, or custom HTML builders.
Use it for
- Generate HTML reports or dashboards programmatically from Python data structures.
- Build HTML fragments dynamically in web frameworks or template systems.
- Construct email bodies or HTML documents for automated document generation.
- Create interactive HTML output for Jupyter notebooks or data analysis tools.
- Serialize Python objects to structured HTML for web display or export.
