Justinmind

For UX/UI designers and product teams who need structured wireframes and clickable prototypes—not Figma as the default design-system hub, and not Banani-style AI screen generation as the core loop. Justinmind is a desktop app for UI design, forms, interactions, and stakeholder review, with imports from Sketch, Adobe XD, and Figma. Prefer Figma for daily multiplayer UI, Axure for heavy conditional logic, or Banani when prompt-to-UI is the job.

Wireframing & Prototyping

Freemium

Use it when

You prototype web or mobile flows with real interactions and need a dedicated wireframe/prototype app—especially if HTML handoff or requirements tooling matters later.

What it does well

Free: UI wireframing, forms, vector tools, png/jpg/svg export, unlimited screens/viewers, 1 project, import from Sketch/XD/Figma
Standard: unlimited projects, advanced interactions, collaboration/roles, mobile testing, variables, shared UI libraries
Professional: Masters, smart templates, data/forms simulation, user flows, fully interactive HTML export, custom branding
Enterprise: SSO, requirements management, Jira/Azure DevOps, document generation, priority support
Device emulator on all tiers; pay per editor with optional perpetual licensing paths on the pricing page

Skip it when

You need more than one active project on Free—upgrade to Standard for unlimited projects
Advanced interactions, collaboration, or responsive prototyping are required—those start at Standard
HTML export, Masters, or user flows are must-haves—plan for Professional
Your team lives in Figma for design systems and multiplayer editing as the daily driver
You mainly want AI prompt-to-multi-screen UI—Banani or similar fits better

Fits your workflow

Wireframe screens in Justinmind → add interactions and (on higher tiers) data/flows → share for review or mobile test → export images or interactive HTML (Pro+) → hand off to engineering. Import existing Sketch/XD/Figma work when starting from other tools.
