FastHTML vs. Streamlit - The Dashboarding Face Off

🔊 Recorded at PyCon DE & PyData 2025, April 25, 2025 https://2025.pycon.de/program/WCDPLP/ 🎓 A hands-on comparison of FastHTML and Streamlit reveals how dashboard framework choices impact development complexity and maintainability at different scales. Speakers: Tilman Krokotsch Description: In this technical comparison, Tilman Krokotsch examines two Python frameworks for building interactive data dashboards: FastHTML and Streamlit. Through live demonstrations and code examples, he illustrates the key differences in implementation approaches, performance characteristics, and developer experience. The presentation explores fundamental aspects including data loading, interactive visualizations, authentication systems, and multi-page navigation. While Streamlit excels in rapid prototyping with its straightforward top-down execution model and rich ecosystem of integrations, FastHTML offers more granular control through its route-based architecture and HTMX foundation. Krokotsch demonstrates how Streamlit's simplicity can become a limitation when implementing more complex features like custom layouts or state management, whereas FastHTML's web-standard approach provides greater flexibility despite requiring more initial setup. The comparison culminates in a practical recommendation: Streamlit is optimal for quick, disposable dashboards, while FastHTML proves more suitable for maintainable, production-grade applications. Notably, FastHTML's adherence to web fundamentals offers developers transferable knowledge of HTML, CSS, and modern web architecture patterns. ⭐️ About PyCon DE & PyData: The PyCon DE & PyData conference unite the Python, AI, and data science communities, offering a unique platform for collaboration and innovation.
