Starter costs $16/editor/month billed yearly for a tool with a long track record in the category, cheap relative to full-fidelity design tools.
The product is positioned around an intentionally rough, low-fidelity style meant to produce a usable wireframe quickly rather than a polished mockup.
Delivers on its stated promise of fast wireframing rather than full prototyping; unlimited reviewers and reusable components are present on every Cloud plan.
Within the broader prototyping category, Balsamiq's fidelity ceiling is intentionally low: no interactive prototyping or design-token system is described, unlike higher-fidelity tools.
Export is limited to PDF or image on the plans reviewed; no mention of exporting projects to an open, editable format or an API.
