The open-source BI platform that turns your dbt project into a governed, version-controlled analytics engine.

Build high-performance, complex interactive dashboards and data-driven web apps entirely in Python.
Panel is a high-level Python library designed for creating sophisticated interactive dashboards and web applications by connecting widgets and parameters to plots, images, and tables. As of 2026, Panel has solidified its position as the primary alternative to Streamlit for complex, production-grade enterprise data applications. Unlike more restrictive frameworks, Panel allows developers to work with almost any Python plotting library (Matplotlib, Plotly, Bokeh, Altair, etc.) and offers three distinct APIs: a simple reactive API for rapid prototyping, a functional API for precise control, and a class-based API for large-scale application development. Its technical architecture is built on the Bokeh server protocol, enabling high-performance bi-directional communication between the Python backend and the JavaScript frontend. A key market differentiator in 2026 is its robust support for WebAssembly (Wasm) via Pyodide and PyScript, allowing for 'serverless' deployment where the Python code runs directly in the user's browser, eliminating backend infrastructure costs for many visualization use cases. This makes it a top choice for Lead AI Architects who require the flexibility of Python with the deployment ease of a static website.
Compiles Python-based apps into WebAssembly to run entirely in the browser without a Python server.
