GenMB builds single-page and multi-page full-stack web applications including SaaS dashboards, e-commerce stores, landing pages, portfolios, CRM tools, booking systems, and more. GenMB generates complete projects with multi-page routing, state management, a database (a zero-config key-value store or a dedicated PostgreSQL database), and 80 plugin integrations.

GenMB requires no coding experience - simply describe what you want in plain English, and the AI will generate the code for you. If you know how to code, you can copy and customize the generated code in the built-in editor.

GenMB generates clean HTML, CSS, and JavaScript code using Tailwind CSS for styling. You can choose between Vanilla JS, React, or React + TypeScript frameworks. Frontend apps run instantly in-browser via ESM CDN. Backend apps get a Cloud Run Dev Sandbox with real server execution and package management.

No. GenMB (pronounced "gen-em-bee") is an AI app builder and full-stack development platform at genmb.com that lets you build, deploy, and host web apps from plain-English prompts. It is not affiliated with Genmab, the Danish biotechnology company, or with Generate Biomedicines. Search engines sometimes auto-correct "GenMB" to "Genmab" because the names look similar, but they are completely different companies in different industries.

Most apps generate in 15 to 60 seconds. Simple single-page apps (landing pages, calculators, portfolios) take 15 to 30 seconds. Complex multi-page full-stack apps with databases and authentication take 30 to 90 seconds. Agent Mode for very complex apps runs 5 to 15 sequential tasks and may take 3 to 8 minutes, but shows real-time progress throughout.

Yes, GenMB builds complete full-stack applications and automatically provisions backend infrastructure when your app needs it. Describe an app requiring user accounts, data persistence, or APIs, and GenMB generates the data layer, authentication flows, and create/read/update/delete operations. Simple apps get a zero-config key-value store; data-heavy apps get a dedicated PostgreSQL database. You can also wire in Supabase or other services through the plugin system.

GenMB provides two built-in database options. The Key-Value Store is zero-config persistence for simple apps - save and load data by key with no schema and no setup, available on every plan including Free. The Relational Database is a dedicated PostgreSQL database (Pro and above) for apps with foreign keys, joins, and complex queries, and includes an interactive Schema Designer and Database Browser. The AI auto-detects which fits your app, and no API keys are needed for either. If you prefer to bring your own backend, you can connect Supabase or Firebase through the plugin system.

Yes, GenMB supports TypeScript. Choose React + TypeScript as your framework and GenMB generates fully typed TSX components, interfaces, and utility functions. TypeScript projects use Vite for transpilation with a generated tsconfig.json. The Code Healer understands TypeScript and preserves type annotations during fixes. Available on all plans.

Yes. GenMB generates full SaaS apps with Google OAuth authentication (built-in), Stripe subscription billing, user dashboards, and multi-tenant data isolation. Enable the Clerk or Auth0 plugin for more auth options. The generated code handles sign-up flows, subscription gating, webhook-based billing events, and role-based access control out of the box.

Yes. GenMB apps include built-in end-user authentication so the people using your app can create accounts and sign in with Google, email and one-time code, or magic links - no separate auth service to wire up. You can also collect payments from your users with built-in Stripe billing, from one-off checkouts to recurring subscriptions. Credentials and keys are stored encrypted and handled server-side, so they never appear in your app's client code.

GenMB Agent Mode is an autonomous AI feature for building complex apps. When enabled, the AI breaks your request into 5-15 sequential tasks, executes each with automatic error recovery (up to 3 retries), and creates checkpoints after each successful task. You can pause, resume, or stop the process at any time.

Yes, GenMB supports PWA (Progressive Web App) generation so your app works offline as a mobile app. Enable the PWA toggle when creating your app, and GenMB will automatically generate a manifest.json, service worker, and offline fallback page. Your app can then be installed on mobile devices and work offline.

Yes, GenMB supports uploading images and other files through static asset management. You can upload images (JPG, PNG, GIF, WebP, SVG), fonts (WOFF, WOFF2, TTF), data files (JSON, CSV, XML), documents (PDF), audio (MP3, WAV), and video (MP4, WebM). Each file can be up to 10MB, with 100MB total storage per app.

Yes, GenMB provides version history and automatically saves versions of your app as you make changes. You can view the version history, preview any previous version, and rollback to it instantly with atomic transactions ensuring data consistency.

Yes, GenMB lets you add Supabase, Stripe, authentication, and more through 80 built-in plugin integrations across payments, auth, storage, analytics, and AI. Popular ones include Supabase (database, auth, storage), Stripe (payments), and Clerk (user management). Enable them in the Integrations panel, add your API keys, and the AI automatically generates code that works with your configured services. You can also manage environment variables and secrets through the Env Vars panel.

Design View is a visual theme editor in the app editor. It extracts design tokens (colors, fonts) from your live preview, lets you swap colors, change typography, or apply pre-built theme presets - all with instant live preview. When you apply, the AI rewrites your source code with the new design system.

Yes, GenMB lets you queue up to 10 prompts at once with Prompt Queue while the AI is processing your current request. Queued prompts execute automatically in order when the current generation completes. You can also remove or clear queued items before they run.

Yes. GenMB includes 19 pre-built workflow templates covering common automation patterns like scheduled Airtable digests, API health monitoring, database report emails, AI-powered request classification, Slack message summarization, and Google Sheets data transforms. Import any template with one click and customize it in the visual workflow builder.

Yes. Toggle Plan Mode (Brain icon) in the chat panel to get a structured analysis of what will be built - covering affected files, implementation plan, and trade-offs - before any code changes. For complex multi-page apps, GenMB also auto-generates architecture plans. GenMB Code (Pro) adds execution plans with approve/reject gates for full control.

Yes. Every code generation runs through an OWASP Top 10 security scanner that detects XSS, exposed secrets, SQL injection, CORS misconfigurations, and more in ~50ms. Unlike competitors that only report issues, GenMB auto-fixes critical and high-severity findings through the Code Healer. You receive clean, security-hardened code with a security score on every generation - available on all plans including Free.

Yes, you can collaborate with your team on GenMB apps through team workspaces with collaborator roles, so multiple people can work on apps together. You can also sync with GitHub for push/pull workflows, share apps via public links, or export as ZIP for your preferred development environment.

GenMB Code is an AI-powered coding assistant (Pro feature) that provides precise, file-level edits within your app. Unlike chat refinement which regenerates code, GenMB Code makes targeted modifications - fixing a specific function, updating a component, or adding a feature - with execution plans you can approve or reject before changes are applied.

Yes. GenMB supports Figma import - paste a Figma frame URL and the AI converts your design into working code. It preserves layout structure, spacing, typography, and colors. Works best with well-organized Figma files using auto-layout. Available on all plans.

The Marketplace is a community library of app templates created by GenMB users. Browse, preview, and install templates to use as starting points for your own projects. You can also publish your apps as templates for others to use, with ratings and install counts tracking popularity.

Plan Mode and Agent Mode serve different purposes. Plan Mode (available in chat) asks the AI to write a structured plan - listing affected files, implementation steps, and trade-offs - before making any code changes. You review the plan, then approve. Agent Mode is a fully autonomous builder: it breaks complex requests into 5-15 tasks, executes each one sequentially with error recovery, and creates checkpoints. Plan Mode is for controlled iteration; Agent Mode is for building complex apps hands-free.

Yes, you can copy and use the generated code with one click and use it anywhere. The code is yours to modify, extend, and deploy as you see fit. You can also download the entire app as a ZIP file for local deployment.

Yes, you can edit the generated code in a built-in code editor powered by CodeMirror with syntax highlighting. You can also use the Visual Editor to click elements and modify them directly, or use GenMB Code (Pro) for AI-assisted precise edits. Code Healer automatically detects and fixes errors. All changes are saved with version history.

Yes. Pro and Business plans include GitHub Sync, which pushes your app's code to a GitHub repository. Changes sync automatically when you save. You can also pull changes from GitHub back into GenMB, enabling a hybrid workflow between AI generation and traditional development.

Yes, you own 100% of the code GenMB generates. All generated code belongs to you with no licensing restrictions, attribution requirements, or royalty fees. Export it as ZIP, sync to GitHub, or deploy anywhere. Use it for personal projects, client work, or commercial products. There is no vendor lock-in.

Yes, you can share your GenMB apps with others by making them public so others can view and get inspired by them. Public apps appear in the Discover section and can be viewed by anyone. Each public app gets its own shareable URL.

Yes, GenMB lets you deploy your app to a custom subdomain like yourapp.genmb.com with SSL/HTTPS included. Deployment is instant and the URL is immediately shareable.

Yes. GenMB generates input validation, authentication guards, server-side access controls, and proper error handling. The code follows best practices and is ready for production deployment. You get full source code access to customize further.

Generated apps work in all modern browsers including Chrome, Firefox, Safari, and Edge. The code uses standard web technologies and Tailwind CSS, ensuring broad compatibility.

GenMB uses advanced AI models with specialized prompts optimized for app generation. The AI understands natural language descriptions and generates appropriate code structures, components, and styling. You can refine your app through chat conversations to make adjustments.

Yes, GenMB-generated apps are good for SEO because GenMB generates semantic HTML with proper heading structure and responsive design. PWA-enabled apps include all necessary manifests and service workers. The generated code uses web standards that search engines understand, and you can customize meta tags and content as needed.

GenMB uses multiple advanced AI models with task-specific configurations optimized for code generation, refinement, and error healing. Different tasks use different model settings - code generation prioritizes accuracy while chat uses a more conversational tone. All models are accessed via a unified provider system.

Yes. GenMB can generate apps that receive webhooks from services like Stripe, GitHub, or Twilio. For automations, GenMB Workflows include a Webhook Trigger node - publish a unique endpoint URL and any HTTP POST to it runs your workflow. Webhook payloads are available as template variables throughout the workflow.

For GenMB's own generation engine, no - it uses its own AI infrastructure. However, if your generated app needs AI features (a chatbot, image generation, text completion), you can plug in your own API keys via the plugin system (OpenAI, Anthropic, HuggingFace plugins). These keys are stored encrypted and injected server-side so they never appear in client code.

GenMB generates code using semantic HTML (proper heading hierarchy, landmark elements, button/link roles) and Tailwind CSS which respects focus states. ARIA attributes are included for interactive elements. While GenMB doesn't guarantee full WCAG 2.1 AA compliance - that requires manual audit for specific apps - the generated baseline significantly reduces accessibility issues compared to manually written code.

GenMB generates web application code. Frontend: HTML, CSS, JavaScript (Vanilla JS), JSX/JavaScript (React), or TSX/TypeScript (React + TypeScript). Backend: Python (FastAPI) for apps that require server-side logic, APIs, or database access. All generated code uses standard languages with no proprietary syntax - you can read, modify, and run it with any standard toolchain.

Yes, GenMB is free to use, offering 5 credits per day and unlimited apps on the Free plan. All frameworks, live preview, version history, and deployment are included. No credit card required. Upgrade to Pro for more credits.

GenMB usage limits are generous: the Free plan includes 5 credits per day, unlimited apps, 50MB per file upload, and 1GB total storage per app. Pro ($19/mo) gives 300 credits per month and increases storage to 250GB per app. Team Starter ($49/mo) covers unlimited users on your email domain with a shared pool of 1,000 credits/month. The Business plan ($397/mo) adds AI Agents, Workflows, and dedicated infrastructure with 5,000 credits/month shared across the team.

The GenMB Business plan works as one subscription ($397/mo) that covers unlimited users at your company. All users with the same email domain (e.g. @yourcompany.com) automatically get full access including AI Agents, custom GKE deployment, and dedicated support. No per-seat charges.

GenMB's Free plan is free forever - not a trial or limited-time offer. You get 5 credits per day, unlimited apps, all four frameworks (Vanilla JS, React, React + TypeScript, React Native), live preview, version history, subdomain deployment with SSL, and ZIP export. No credit card required, no expiry date.

On the free plan you can build and deploy real, live apps: landing pages, portfolios, SaaS dashboards, booking systems, e-commerce storefronts, calculators, games, internal tools, and more. Every app gets a live subdomain (yourapp.genmb.com) with HTTPS. You get full source code access and can export as ZIP. You get 5 credits per day with unlimited apps, more than enough to ship real projects. Top up anytime for more credits.

GenMB's free plan is more generous than most competitors. Bolt.new and Lovable use token-based credits that deplete quickly - a single complex generation can burn through a significant portion of your monthly allowance. GenMB gives you 5 credits per day, every day, with no token counting. You also get subdomain deployment, version history, and four frameworks on the free tier - features that are paid-only elsewhere.

Yes, you can earn free GenMB credits by inviting a friend - you both get $30 in app credits (200 credits) when they sign up. Pro and Business plans also earn an extra $80 (500 credits) whenever an invited friend upgrades to Pro. There's no cap on referrals. Your invite link is in Settings under the Referrals card.

Credits are how GenMB meters AI work - each generation, refinement, or agent run uses credits based on its complexity. The Free plan gives you 5 credits that reset every day, so you can keep building without a subscription. Paid plans grant a monthly pool instead: Pro includes 300 credits per month and rolls unused credits over (up to 600). Previewing, editing, deploying, and viewing version history never cost credits. If you run out, you can buy top-up credit packs anytime - they don't expire.

GenMB offers 17 pre-built automation templates across 6 categories: Data Cleanup, Data Transform, Reporting, File Processing, API Tools, and Utilities. Templates provide a starting point with predefined prompts and input fields for common use cases.

GenMB offers complete full-stack generation with auto-provisioned databases (Firestore + PostgreSQL), not just frontend code. Where v0.dev focuses on UI component generation, GenMB adds full app orchestration: databases, security scanning, backend runtime, and deployment. Compared to Bolt.new, you get 80 plugin integrations, a Visual Editor, Code Healer, Schema Designer, Database Browser, and environment variable management with one-click deployment.

Unlike visual builders that output proprietary code, GenMB generates clean, exportable HTML, CSS, JavaScript, React, or TypeScript code. You get full source code ownership with zero vendor lock-in. GenMB is also conversational - describe what you want in plain English instead of dragging and dropping elements. You can export your code and host it anywhere.

GenMB is purpose-built for complete app generation, not just code snippets. It provides live preview, database provisioning, Code Healer, Visual Editor, Agent Mode, 80 plugin integrations, one-click deployment, version history, and subdomain hosting, all integrated. You get a working, deployable full-stack app with a database, not just code to copy and paste.

Yes, you can use GenMB for commercial projects and you own 100% of the code GenMB generates. Use it for client projects, sell apps you create, or build your startup - no attribution required, no licensing fees, no restrictions. The code is yours to commercialize however you choose.

Yes. Pro and Business plans support custom domains with automatic SSL certificates. Connect your domain in the deployment settings, update your DNS records, and your app is live at your own URL within minutes. Subdomain deployment (yourapp.genmb.com) is available on all plans including Free.

GenMB offers two deployment tiers. Shared deployment on Cloud Run costs ~$0.50/app/month and serves static assets with CDN-level caching (ETags, no-cache headers for freshness). GKE deployment provides dedicated Kubernetes pods with auto-scaling for apps needing consistent performance under load.

Yes, you can embed your GenMB app on another website using embed tokens that allow iframe embedding on external sites. Generate an embed token in the deployment settings, then use the provided iframe code on any website. Access controls ensure only authorized domains can embed your app.

Yes. Every deployed app includes built-in analytics tracking page views, unique visitors, and user sessions. The deploy service automatically injects a lightweight analytics script. You can also add Google Analytics or other third-party analytics via plugins.

Yes. Export your app as a ZIP file and deploy it anywhere: Vercel, Netlify, AWS, Google Cloud, or your own VPS. The exported code has no GenMB dependencies - it's plain HTML/CSS/JS or a standard React/Vite project. For apps with GenMB's backend services (database, auth, file storage), you'd need to wire up your own backend or use the plugin equivalents (Supabase, Firebase, etc.).

The Schema Designer is a visual tool for designing your app's database structure. Define tables, columns, types, and relationships through a drag-and-drop interface. The AI uses your schema to generate type-safe database queries, CRUD operations, and form validation - eliminating manual schema-to-code translation.

Yes. GenMB supports data connectors for Airtable, Google Sheets, Notion, and REST APIs. Configure a connector in the Integrations panel, and the AI generates code to read, write, and sync data between your app and the external source. Each connector handles authentication, pagination, and error handling automatically.

Yes. The Vector DB service provides pgvector-backed semantic search with automatic text chunking, embedding generation, and similarity queries. Use it to build RAG (Retrieval Augmented Generation) applications, semantic search engines, or AI-powered content recommendations. Available on Pro and Business plans.

Yes, in two ways. First, use data connectors (Airtable, Google Sheets, Notion, REST API) to pull data from existing sources into your generated app. Second, use the Supabase or Firebase plugins and point them at your existing project - GenMB generates code that talks to your existing database schema. For PostgreSQL, configure the connection string in the app's environment variables.

Data Insights is an AI-powered analytics feature that analyzes your app's database and generates natural language summaries, trends, and recommendations. Ask questions about your data in plain English - "What are the most popular products this week?" - and get AI-generated answers with charts. Available on Pro and Business plans.

Code Healer is GenMB's automatic error detection and repair system. After every code generation, it validates the output for syntax errors, broken imports, undefined references, and runtime issues. When errors are found, it iteratively analyzes root causes and applies fixes - up to 15 rounds for single-file apps, 25 rounds for multi-file projects. It also runs OWASP security scanning and auto-remediates critical findings.

GenMB uses a multi-tier AI provider system. Fast tasks like intent detection and title generation use Gemini Flash for speed. Complex tasks like code generation, refinement, and healing use advanced-tier models (Gemini Pro or GPT). Each model has a 2-deep fallback chain that crosses provider boundaries - if one model fails, the system automatically falls back to an alternative.

Yes, you can build an AI chatbot into your generated app by enabling the AI Chatbot service in the capabilities panel, and GenMB generates a fully functional chat interface with AI responses powered by GenMB's backend. The chatbot SDK handles conversation history, streaming responses, and custom system prompts. Available on all plans.

Yes, GenMB supports image and video generation. The Image AI service generates images from text prompts within your app. Video AI (Pro and Business plans) generates short videos using Sora 2. Both services are accessed through SDKs injected into your generated code - no API key management needed on the client side.

Backend Agents are server-side AI agents that run in isolated Cloud Run sandboxes. They can execute Python code, call APIs, process data, and respond to webhooks - all without client-side code. Build them by describing the agent's behavior in natural language. GenMB generates the agent code, deploys it, and provides a callback URL for integration.

Chat Agents are AI assistants that live in your messaging channels instead of inside an app. Describe what the agent should do in plain English, connect it to Telegram, Slack, or Email, and it responds to messages automatically - answering questions, looking up data, or triggering workflows. Chat Agents are available on the Business plan and run server-side, so they keep working even when no one has the app open.

The Assistant Widget is an embeddable AI chat interface you can add to any GenMB app. It provides a floating chat button that opens a conversational AI assistant trained on your app's context. Users can ask questions, get help, or trigger actions. Configure the assistant's personality, knowledge base, and capabilities in the Assistants panel.

The security scanner checks for OWASP Top 10 vulnerabilities: XSS (cross-site scripting), SQL injection, exposed API keys and secrets, CORS misconfigurations, insecure direct object references, SSRF (server-side request forgery), and more. Scanning runs in ~50ms with no LLM dependency, and findings are auto-remediated through Code Healer.

API keys configured in the Integrations panel are stored encrypted in Firestore using industry-standard encryption, never exposed in generated client-side code. When your app runs, SDK calls route through GenMB's proxy layer which injects credentials server-side. Your keys never appear in the browser's network tab or source code.

GenMB Workflows are visual automation pipelines that connect triggers (webhooks, schedules, events) to action nodes (AI processing, API calls, data transforms, email). Build them in a drag-and-drop node editor with 20+ workflow node types. Use pre-built templates for common patterns like scheduled reports, AI classification, and data sync.

Yes. The Schedule Trigger node supports cron-based scheduling - run workflows every minute, hourly, daily, weekly, or with custom cron expressions. Scheduled workflows execute server-side with automatic retry on failure. Available on Pro and Business plans.

MCP (Model Context Protocol) is an open standard for connecting AI tools to external services. GenMB exposes an MCP server with 7 tools (list apps, get app details, list and read files, write and edit files, deploy an app) that work with Claude Code, Cursor, and other MCP-compatible clients. You can also connect external MCP servers to your GenMB apps. Authenticate via API keys with the genmb_sk_ prefix.

Workspaces let multiple users collaborate on shared apps. The workspace owner invites members who can view, edit, or manage apps based on their role. All members see the same apps, versions, and deployments. Workspace billing is centralized under the owner's subscription.

Yes, GenMB supports SSO (Single Sign-On) on the Business plan with SSO configuration for your organization's domain. Once configured, all users with your email domain are automatically authenticated and provisioned into your workspace without individual account setup.

GenMB builds Progressive Web Apps (PWAs) that install on iOS and Android home screens, work offline, and feel like native apps. PWAs support push notifications, offline caching, and full-screen display. For truly native iOS/Android apps with hardware access, you would need React Native - GenMB focuses on PWAs which cover most mobile use cases without app store requirements.

Yes, GenMB apps work on mobile devices because all generated code uses responsive design via Tailwind CSS, so apps automatically adapt to phone, tablet, and desktop screens. With PWA enabled, users can install your app to their home screen for an app-like experience with offline support.
