Wireflow (wireflow.co) is a free, open-source online tool for creating user-flow prototypes: 100+ pre-built realistic screen wireframe templates across 10 categories, connected with flow arrows, with real-time collaboration and live chat.
Completely free, open source, no paid tiers.
Designers wanting to combine wireframes and flow diagrams into one artifact (a "wireflow") without needing full mockup fidelity or design-tool expertise.
Starting from realistic screen templates (not abstract boxes) gives user flows more visual context than a plain flowchart, while requiring far less effort than building complete mockups for every screen.
Wireflow is a free, online, open-source tool for designers to create user flow prototypes without advanced software.
