Frequently Asked Questions
What is the main difference between Streamlit, Gradio, and Dash?
Streamlit focuses on converting Python data scripts into interactive web apps with a script-first reactive model. Gradio specializes in building ML model demos with 40+ components for diverse data types and deep Hugging Face integration. Dash provides the most powerful charting capabilities through its Plotly.js foundation and targets production-grade analytical dashboards with enterprise features like Kubernetes scaling and LDAP authentication.
Which framework is best for machine learning model demos?
Gradio is the strongest choice for ML model demos. It was built specifically for this purpose and offers 40+ components designed for ML data types including images, audio, video, and 3D models. Gradio lets you create a working model interface in as few as three lines of Python, generate instant public sharing links, and deploy permanently to Hugging Face Spaces for free. Streamlit can also serve ML demos but requires more code and lacks the specialized ML-focused components that Gradio provides.
Are Streamlit, Gradio, and Dash all free to use?
All three frameworks are free and open source. Streamlit uses an Apache-2.0 license and offers free public app hosting through Community Cloud. Gradio also uses an Apache-2.0 license and provides free permanent hosting on Hugging Face Spaces with auto-scaling. Dash uses an MIT license and is free for self-hosted use. Each framework offers paid enterprise tiers for organizations that need production deployment features, authentication, and dedicated support.
Which framework has the best data visualization capabilities?
Dash has the most powerful native visualization capabilities thanks to its Plotly.js foundation, offering 50+ chart types including statistical, scientific, financial, and geographic maps. Streamlit provides solid built-in charts and supports integration with Plotly, Altair, Matplotlib, and Vega-Lite for flexibility. Gradio includes a Plot component that works with Matplotlib and Plotly but is primarily optimized for ML model input/output rather than standalone data visualization dashboards.
