Everything you need to know about GenMB

What types of apps can I build with GenMB?
You can build 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, databases (Firestore or PostgreSQL), and 50+ integrations.
Do I need coding experience to use GenMB?
No coding experience is required! 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.
What technology does GenMB use to generate apps?
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.
Can GenMB really build full-stack applications?
Yes! GenMB automatically provisions backend infrastructure when your app needs it. Describe an app requiring user accounts, data persistence, or APIs, and GenMB will generate Firestore database, security rules, authentication flows, and CRUD operations. You can also enable Supabase for PostgreSQL.
What types of databases does GenMB support?
GenMB supports two database backends: Firestore (NoSQL) for document-based apps, and PostgreSQL via Firebase Data Connect for relational apps with foreign keys, joins, and complex queries. The AI auto-detects which database type fits your app. You can also enable Supabase for PostgreSQL with real-time subscriptions. All options include an interactive Schema Designer, Database Browser UI, and production-ready security rules.
What is Agent Mode and how does it work?
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.
