PyWry

Active·★ 99·Apache-2.0·Updated 2026-10-13

PyWry is a cross-platform rendering engine and UI toolkit for Python with one API and three output targets: a native window using the operating system's webview through PyTauri (not Qt or Electron), a Jupyter widget for JupyterLab, VS Code and Colab, and a browser tab served by FastAPI with a Redis state backend for scaling out. The idea is to prototype a data app in a notebook, deploy it as a web app, and compile it into a standalone desktop executable with the pywry[freeze] extra.

It includes toolbar components such as buttons, selects, sliders and modals defined as Pydantic models, two-way events between Python and JavaScript, Plotly and AgGrid integrations, a streaming chat widget with pluggable providers (OpenAI, Anthropic, Magentic, Agent Client Protocol and LangChain Deep Agents), and extended TradingView charts. Its MCP server lets Claude Desktop, Claude Code or Cursor drive widgets, charts and dashboards, and the repository also ships a Claude Code plugin with the same tools, a skill, slash commands and a subagent.

Features

01Native window using the OS webview, not Qt or Electron
02Jupyter widget that works in JupyterLab, VS Code and Colab
03Optional MCP extra for agent integration
02

Why choose it

+One Python API targets a native window, a Jupyter widget and a browser tab, with PyInstaller support for standalone executables.
+Uses the system webview instead of Electron or Qt, so you can write plain HTML, CSS and JavaScript.
+Built-in chat widget works with several LLM providers, and charts include a rich TradingView integration.
+Offers an MCP server and a Claude Code plugin so agents can build and update widgets.
03

Trade-offs

!The MCP server is one feature of a larger UI toolkit, so it is not a lightweight standalone MCP server.
!On Linux you must install system webview libraries (WebKitGTK and related packages) before it will run.
!It has many optional extras (notebook, auth, freeze, sqlite, several chat providers), so setup depends on which pieces you need.
