What is GenMB?
GenMB is an AI full-stack development platform that turns natural-language prompts into production-ready web apps - frontend, backend, database, authentication, and APIs - then adds post-generation orchestration: an 80-plugin ecosystem, a visual workflow builder, scheduled and chat agents, MCP server support, and one-click deploy to custom domains. It generates React + TypeScript apps built with Vite, is free to start with unlimited apps, and offers Pro from $25/month.
GenMB (gen-em-bee) is an AI app builder. It is not affiliated with Genmab, the biotechnology company.
Describe what you want to build, and GenMB generates complete, deployable source code with automatic error healing and security scanning.
How GenMB Works
From idea to deployed app in four steps.
Describe your app in plain English
Tell GenMB what you want to build using natural language. For example: "Build a project management dashboard with task boards, team assignment, and deadline tracking." GenMB understands your intent and plans the application structure.
AI generates multi-file code with error healing
GenMB generates complete source code across multiple files - HTML, CSS, JavaScript/TypeScript, backend logic, and database schemas. Code Healer automatically detects and fixes any errors during generation.
Preview, edit visually, refine via chat
See your running app in a live preview. Click elements to edit them visually, or describe changes in chat - "make the sidebar collapsible" or "add a dark mode toggle." Iterate until it's exactly right.
Deploy to your custom domain
Deploy with one click to yourapp.genmb.com or connect your own custom domain with automatic SSL. Your app is live and accessible to users within seconds.

Frequently Asked Questions
What is GenMB?
GenMB is an AI full-stack development platform that turns natural-language prompts into production-ready web apps - frontend, backend, database, authentication, and APIs - then adds post-generation orchestration: an 80-plugin ecosystem, a visual workflow builder, scheduled and chat agents, MCP server support, and one-click deploy to custom domains. It generates React + TypeScript apps built with Vite, is free to start with unlimited apps, and offers Pro from $25/month.
Is GenMB the same as Genmab?
No. GenMB (pronounced "gen-em-bee") is an AI app builder at genmb.com. It is not affiliated with Genmab, the Danish biotechnology company (ticker GMAB), or with Generate Biomedicines. Search engines sometimes auto-correct "GenMB" to "Genmab" because the names look alike, but they are different companies in different industries.
How does GenMB generate code?
GenMB uses Google Gemini and OpenAI models to generate complete multi-file source code from your natural language description. The generation pipeline includes intent detection, planning, multi-file code generation, automatic error healing (Code Healer), security scanning (OWASP Top 10), and enhancement passes - all running automatically.
Is GenMB free?
Yes. GenMB offers a generous free tier with 8 credits per day, up to 40 a month, unlimited apps, and subdomain deployment. The Pro plan ($25/month) adds GenMB Code, custom domains, AI Agents live on Telegram, Slack, and Email, more storage, and advanced features. Every plan includes unlimited team members; Team ($59/month) adds a shared credit pool and company-only apps, and Business ($129/month) adds enterprise SSO. Every paid plan has a 30-day money-back guarantee if you haven't used any credits.
What frameworks does GenMB support?
New GenMB apps are React + TypeScript, built with Vite and styled with Tailwind CSS. GenMB installs the packages and runs the build for you, so there is nothing to set up.
How is GenMB different from Bolt.new and Lovable?
GenMB's clearest differences come after generation: a visual workflow builder with 19 node types, scheduled and chat agents, and 80 AI-aware plugin integrations across 15 categories. Fixing breakage GenMB finds in your app is free (up to 2 tries per error), while each Bolt fix attempt uses tokens and Lovable gives 10 free fixes a day. Custom domains are available on Pro and Business, and the Pro plan starts at $25/month.
