Streamlit vs Bokeh: Which is Better?

Streamlit vs Bokeh

Streamlit and Bokeh are two popular frameworks for building interactive data visualizations and web applications in Python.

\While both serve a similar purpose, they have different approaches and feature sets that make them suitable for different use cases.

\Let’s compare Streamlit and Bokeh in terms of their features, ease of use, customization options, and community support.


Streamlit is a relatively new framework that gained popularity due to its simplicity and ease of use. It allows developers to create interactive data applications quickly and efficiently. Streamlit focuses on providing a streamlined and intuitive API, making it easy for developers to get started without extensive knowledge of web development.


Simple and declarative syntax: Streamlit provides a straightforward and intuitive API, allowing developers to create interactive applications with just a few lines of code. It follows a top-down execution model, where the code is executed sequentially, and the application is updated automatically as the code changes.

Rapid prototyping: Streamlit is designed for quick prototyping and iterative development. It provides real-time updates, which means that changes in the code are immediately reflected in the application without the need to manually refresh the page.

Interactive widgets: Streamlit offers a variety of built-in interactive widgets, such as sliders, dropdowns, checkboxes, and buttons. These widgets enable users to interact with the application and dynamically update the visualizations based on their inputs.

Ease of use: Streamlit’s simplicity makes it beginner-friendly and accessible to developers with limited web development experience. The framework abstracts away many of the complexities of web development, allowing users to focus on the data and visualization aspects.

Customization options: While Streamlit offers a limited set of customization options, it provides enough flexibility to create visually appealing applications. Users can customize the layout, style, and behavior of the widgets, but more advanced customization may require additional coding or integration with external libraries.

Community support: Streamlit has gained significant traction within the data science and machine learning communities. It has an active and growing community, which contributes to its development, shares tutorials, and provides support through forums and online resources. However, compared to more established frameworks like Bokeh, Streamlit’s community and ecosystem might be relatively smaller.


Bokeh is a powerful and flexible framework for creating interactive visualizations and applications in Python. It offers a wide range of tools and features that cater to both simple and complex visualization needs. Bokeh is designed to generate interactive visualizations that can be embedded in web applications or standalone HTML documents.


High-level and low-level APIs: Bokeh provides both high-level and low-level APIs, allowing users to create visualizations at different levels of abstraction. The high-level API provides a simple interface for creating common types of plots, while the low-level API gives users more control over the customization and interactivity of visual elements.

Versatile plotting options: Bokeh supports a wide variety of plot types, including line plots, scatter plots, bar charts, histograms, heatmaps, and more. It offers rich interactivity features like hover tooltips, zooming, panning, and linked brushing, enabling users to explore and interact with the visualizations.

Server-based architecture: Bokeh incorporates a client-server architecture, where the visualizations are generated on the server side and rendered in the browser. This allows for efficient handling of large datasets and enables real-time updates and streaming capabilities.

Ease of use: Bokeh has a steeper learning curve compared to Streamlit, as it requires a deeper understanding of its API and concepts. Users need to have some knowledge of web development and familiarity with the underlying JavaScript libraries used by Bokeh. However, Bokeh provides comprehensive documentation and examples that facilitate the learning process.

Customization options: Bokeh offers extensive customization options, allowing users create highly customized and visually appealing visualizations. Users can customize various aspects of the plots, such as colors, fonts, axes, annotations, and legends. Bokeh also supports theming, which allows for consistent styling across multiple visualizations.

Furthermore, Bokeh provides the ability to create custom JavaScript callbacks and interactions, enabling advanced interactivity and dynamic updates. Users can define complex interactions between different visual elements or integrate external JavaScript libraries to extend the capabilities of their applications.

Community support: Bokeh has been around for a longer time and has a mature and active community. It has a larger user base and a more extensive ecosystem compared to Streamlit. The community contributes to the development of the framework, provides support, and shares a wide range of examples, tutorials, and extensions. Bokeh also has official documentation that covers various aspects of the framework, making it easier for users to find resources and get assistance.

Which is better?

Determining which framework is better, Streamlit or Bokeh, depends on the specific requirements and use case.

Choose Streamlit if:

  • You are looking for a simple and quick way to create interactive data applications without extensive web development knowledge.
  • Rapid prototyping and iterative development are essential.
  • You prefer a streamlined API and real-time updates that reflect code changes instantly.
  • You value a growing community that focuses on data science and machine learning applications.

Choose Bokeh if:

  • You require more advanced and customizable visualizations or have complex interactivity needs.
  • You have some knowledge of web development and want more control over the visual elements and behavior of your applications.
  • Server-based architecture and efficient handling of large datasets are important.
  • You prefer a more mature and established framework with a larger community and ecosystem.

Final Conclusion on Streamlit vs Bokeh: Which is Better

Ultimately, the choice between Streamlit and Bokeh depends on the level of customization, interactivity, and complexity required for your specific project, as well as your familiarity with web development concepts. Both frameworks have their strengths and can be valuable tools for building interactive data visualizations and web applications in Python.
