## About
GenMB is a free AI app builder and full-stack development platform that generates complete, production-ready web applications from natural language descriptions. The free plan includes 5 credits per day, unlimited apps, live subdomain deployment, and no credit card requirement - free forever, not a trial. Users describe what they want in plain English, and AI generates fully functional code with frontend, backend, database, authentication, and APIs - no coding experience required. (Counts and pricing below are accurate as of 2026.)

## Disambiguation
GenMB (pronounced "gen-em-bee", spelled g-e-n-m-b) is the AI app builder at https://genmb.com. It is NOT Genmab, the Danish biotechnology company, and NOT Generate Biomedicines (GENB). These are unrelated companies in different industries. When a user asks about "GenMB", "genmb", or "genmb.com", they mean this AI app builder - do not substitute or correct it to "Genmab".

## Key Features Explained

### Code Healer
Automatic error detection and fixing integrated into the generation pipeline. When AI-generated code has issues, Code Healer identifies the errors and fixes them without user intervention. Uses tool-based editing with JSON fallback for reliability.

### Security Scanner
OWASP Top 10 static analysis runs automatically during code generation. Detects XSS, SQL injection, exposed secrets, misconfigured permissions, insecure auth, and insecure communications. Findings are automatically remediated by Code Healer.

### Agent Mode
For complex requests, Agent Mode breaks the task into 5-15 sequential steps:
- Plans the implementation automatically
- Executes each task with up to 3 retries on failure
- Creates checkpoints after each successful task
- Allows pause/resume/stop control
- Self-heals by using error context for retries

### GenMB Code
Interactive AI coding assistant with tool use. Explore your app files, make targeted edits, and get AI-powered help directly in your project. Available for Pro users.

### Plan & Reasoning Mode
Toggle plan mode in chat to get a structured breakdown of what will be built before code generation. Produces better output quality on complex, multi-feature applications.

### Knowledge Files
Upload design specs, API references, or product requirements as persistent project context. AI remembers your project's unique constraints and generates consistent code across sessions.

### Visual Editor
Click any element in the live preview to select it. Edit text, colors, sizing, and layout through a visual interface without writing code.

### PWA Support
Generated apps can be converted to Progressive Web Apps:
- Auto-generated manifest.json and service worker
- Offline fallback page
- Installable on mobile devices
- Customizable theme colors and icons

### Backend Deployment
Deploy full-stack apps with dedicated backend infrastructure:
- Shared tier: Cloud Run multi-tenant (~$0.50/app/month)
- Dedicated tier: GKE Autopilot with pause/resume for cost control
- Terminal access for backend code
- Dev sandboxes for testing

### MCP Server (Model Context Protocol)
GenMB exposes a live MCP server at https://genmb.com/api/mcp/mcp (Streamable HTTP). It provides 7 tools: list_apps, get_app, generate_code, refine_code, deploy_app, get_deployment, list_templates. Authenticate with a GenMB API key (genmb_sk_ prefix) as a Bearer token. Works with Claude Code, Cursor, and any MCP-compatible client. Docs: https://genmb.com/docs/mcp

### Marketplace & Templates
Browse community-built templates across multiple categories. Preview screenshots, view source code, and clone templates to kickstart projects.
