Everything you need to author bowtie diagrams.
Bowtie Risk Engine is built around the workflow that engineers actually use in workshops, audits, and reviews. Nothing more, nothing in the way.
Visual editor
A graph-based canvas with snapping, alignment, and pan/zoom that scales to large diagrams. Keyboard shortcuts for adding threats, consequences, and barriers. Multi-select, copy, paste, undo/redo. Auto-layout helpers when a diagram grows past the workshop whiteboard.
Threats and consequences
Each top event can have multiple threat arms on the left and consequence arms on the right. Reorder freely. Each arm is independent — name, description, and ownership are first-class.
Preventive and recovery barriers
Barriers are first-class objects, not just labels on a line. Annotate barrier type, owner, effectiveness, and supporting controls. Distinguish preventive (left of the top event) from recovery (right of the top event) barriers visually.
Escalation factors
Capture the conditions that defeat or degrade a barrier, plus the secondary controls that defend against them. Critical for honest bowties — the difference between a wall chart and a real risk picture.
Export
PNG for slides and reports. SVG for high-resolution prints, posters, and embedding. JSON for version control, code review, diff'ing changes between revisions, and integration with other risk tooling.
Browser and desktop
Run in any modern browser with no install. Or download a signed native app for macOS, Windows, or Linux for offline work, native file dialogs, and the convenience of a real desktop app. Same editor, same files, same export formats.
No sign-up, no lock-in
Open the app and start drawing. Your diagrams are yours, exported in open formats. No account required to use the browser app.
