  SBcoyote is an open-source cross-platform biochemical reaction viewer and
editor released under the liberal MIT license. It is written in Python and uses
wxPython to implement the GUI and the drawing canvas. It supports the
visualization and editing of compartments, species, and reactions. It includes
many options to stylize each of these components. For instance, species can be
in different colors and shapes. Other core features include the ability to
create alias nodes, alignment of groups of nodes, network zooming, as well as
an interactive bird-eye view of the network to allow easy navigation on large
networks. A unique feature of the tool is the extensive Python plugin API,
where third-party developers can include new functionality. To assist
third-party plugin developers, we provide a variety of sample plugins,
including, random network generation, a simple auto layout tool, export to
Antimony, export SBML, import SBML, etc. Of particular interest are the export
and import SBML plugins since these support the SBML level 3 layout and render
standard, which is exchangeable with other software packages. Plugins are
stored in a GitHub repository, and an included plugin manager can retrieve and
install new plugins from the repository on demand. Plugins have version
metadata associated with them to make it install plugin updates. Availability:
