Rocs review
A free, open-source graph workspace for Linux users who script and experiment with graphs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Rocs brings graph editing and algorithm experimentation into a Linux desktop application. Its visual editor lets learners and researchers create nodes and edges, while a JavaScript engine supports implementing and executing algorithms. Graph generators, simulation helpers and automatic layouts extend the workflow from building a graph to observing how an algorithm behaves. The project journal can hold tasks, results or observations alongside graph documents and scripts. That makes Rocs a fit for students, lecturers, researchers and solo users exploring graph theory or data structures; it is less suited to people looking for a general-purpose diagramming tool.
The main strength is the connection between a property-graph model and executable scripting. Users can define custom node and edge types with dynamic properties, generate graphs, and choose force-based or radial-tree layouts. Import and export cover DOT, GML, Trivial Graph Format and KML, and projects can be exchanged as .tar.gz archives. This combination gives an experiment a place for its graph, code and notes, rather than limiting the application to drawing. The scope is still centered on graph algorithms and study, so teams whose priority is broad diagramming or a shared browser-based workspace should consider alternatives.
Rocs is open source and free, distributed by KDE under GPL-2.0-or-later; there are no paid tiers to compare. Its desktop deployment is Linux-only, a decisive constraint for mixed-platform groups and anyone needing Windows or macOS support. Documentation, community, email and chat are listed as support channels, giving learners several routes for guidance. Pick Rocs if Linux is already part of the workflow and graph scripting, generators and experiments are central. Choose another tool if cross-platform access or a wider visual-design focus matters more than an algorithm-oriented workspace.
Rocs pros and cons
- Where it wins
- Edit graph nodes and edges visually, then run JavaScript algorithms.
- Generate graphs, simulate experiments and apply automatic layouts.
- Import and export DOT, GML, TGF and KML graph files.
- Where it doesn't
- Linux-only, so it does not fit Windows or macOS workflows.
- Its focus is graph theory and algorithms, not general-purpose diagramming.
- Desktop deployment may not suit teams seeking a web-based shared workspace.
