For Product Managers

Prototype Without
Developers

Build interactive prototypes and internal tools without waiting for engineering. Validate features with real users, align stakeholders with working demos, and hand developers code instead of specs.

Plan Mode for structured breakdowns. Agent Mode for complex prototypes. Visual editor for quick tweaks. Code export for developer handoff. One-click deploy for user testing.

The Prototype Bottleneck

You know exactly what the feature should do. You can describe every screen, every interaction, every edge case. But turning that vision into something testable requires engineering time — and engineering is always booked three sprints out.

Static wireframes and slide decks lose nuance. Stakeholders nod along to a Figma mockup, then are surprised by the actual implementation. Users give feedback on layouts when what you really need is feedback on workflows. The gap between your product vision and what people can actually interact with slows down every decision.

GenMB closes that gap. Describe the feature in plain English, generate a working prototype in minutes, and put it in front of users the same day. Use Plan Mode to break complex features into structured components. Use the visual editor to adjust on the fly. Deploy with one click and collect real feedback on real interactions — then export the code and hand it to engineering as a reference implementation.

Why Product Managers Choose GenMB

Move from idea to validated prototype without depending on engineering bandwidth.

Prototype Without Waiting for Eng

Skip the sprint backlog. When you have an idea for a feature or tool, build a working prototype yourself in minutes. No tickets, no prioritization debates, no waiting three sprints for a developer to pick it up.

Validate Before Building

Test features with real users before committing engineering resources. Build a functional prototype, run it past your target audience, and gather data. Kill bad ideas early and double down on what works — before a single engineering hour is spent.

Communicate with Working Demos

Show stakeholders interactive prototypes, not wireframes. A clickable demo eliminates the gap between what you envision and what others understand. Executives, designers, and engineers all align faster when they can interact with the actual product.

Reduce Spec Ambiguity

The prototype IS the spec. Instead of writing lengthy PRDs that get misinterpreted, hand developers a working reference implementation. They see exactly what to build — the layout, the interactions, the edge cases. Fewer rounds of revision, fewer misunderstandings.

How Product Managers Use GenMB

From feature validation to developer handoff, GenMB fits into your existing product workflow.

Feature Validation

Build a working prototype of a proposed feature, test it with 5 users, and decide whether to prioritize — in hours, not sprints. Use Plan Mode to break down the feature into structured components, then generate a functional version. Deploy it to a shareable URL and send it to your test group. Real user feedback on a real interface beats hypothetical discussions in every roadmap meeting.

Example prompt:"Dashboard with a Kanban board where users can drag tasks between columns, filter by assignee, and see progress metrics"

Stakeholder Alignment

Build a clickable demo instead of writing another PRD. When you need executive buy-in for a new direction, let stakeholders interact with the vision rather than interpret a document. Use the visual editor to tweak copy and layout in real time during the meeting. Decisions happen faster when everyone is looking at the same working product.

Example prompt:"Customer portal with account overview, usage analytics charts, billing history table, and a support ticket form"

Developer Handoff

Generate the prototype, export the code, and hand it to engineering as a starting point. Developers see the exact UI, interactions, and component structure you intended — no guesswork. Use Agent Mode for complex multi-page prototypes, then export clean React or TypeScript code. Engineering extends it rather than building from scratch, cutting implementation time and reducing misunderstandings.

Example prompt:"Multi-step onboarding wizard with progress bar, form validation, conditional fields based on user role, and a summary review page"

What You Can Prototype

Functional prototypes with real interactions — not static mockups.

  • Feature prototypes for user testing
  • Stakeholder demos and buy-in
  • Spec documentation via working prototypes
  • Competitive analysis tools
  • Internal dashboards for product metrics
  • User onboarding flow testing
  • A/B test variant creation

Product Manager Questions

Do I need coding skills to use GenMB?▼
No. You describe what you want in plain English — the features, the user flow, the data it should display. GenMB generates the full application. You can refine it through chat (describe changes in words), the visual editor (click and edit directly), or Plan Mode (structured step-by-step breakdowns). Many product managers use GenMB daily without writing a single line of code.
Can I hand off GenMB prototypes to developers?▼
Yes. Every prototype generates real, exportable code using standard frameworks — React, TypeScript, Tailwind CSS. Developers can open the codebase, understand the structure immediately, and extend it. The prototype serves as both a visual reference and a code starting point, which is far more useful than a static design file.
How is this different from Figma prototypes?▼
Figma prototypes simulate interactions with linked screens. GenMB prototypes are real applications with actual logic — working forms, data filtering, conditional rendering, state management. Users interact with real functionality, not click-through mockups. This means the feedback you collect reflects actual usability, not just visual preference.
Can I test prototypes with real users?▼
Yes. Deploy any prototype to a live URL with one click. Share the link with testers, run usability sessions, or embed it in a survey. The deployed app works on desktop and mobile with no installation required. You can iterate on the prototype between test sessions and redeploy in seconds.
