Applications supporting GML
- Cytoscape, an open source bioinformatics software platform for visualizing molecular interaction networks, loads and save previously-constructed interaction networks in GML
- yEd, a free Java-based graph editor, supports import from and export to GML
- Tulip software is a free software in the domain of information visualisation capable of manipulating huge graphs (with more than 1.000.000 elements)
