GPL Donate Build Windows Syntax check

Main window

Pywr editor is a user-friendly, free and open‑source graphical user interface (UI) to build and customise pywr models written in JSON-based document format.

Pywr editor provides the following features:

  • Full and easy customisation of model parameters, nodes, recorders, metadata, tables, imports and slots directly from the UI
  • Dynamic validation of model configuration
  • Easily run and debug your model using the toolbar actions
  • Support of custom model components
  • Interactive model schematic
    • pan, zoom, resize, screenshotting
    • drag, drop or delete multiple nodes at the same time
    • connect or disconnect nodes
    • change colour and shape of nodes
  • External data support
    • Automatic parsing of external files to offer suggestions of DataFrame index and column names, and values (from CSV, Excel or HDF files)
    • Data visualisation with charts
    • Import/export value to Excel (Windows only)
  • Windows integration
    • Open JSON files directly in the editor
    • Browse recent files
    • Pin most used models in the taskbar

Note: although the software can run on any system that can run Python, the editor is currently designed to work on Windows only. Upon request the UI can be optimised to work on Linux and Mac platforms.
