Headless CMS UI Design & Prototyping AI Agents

About formcms

FormCMS is an open-source, AI-powered headless content management platform that transforms natural language descriptions into complete full-stack applications including schemas, APIs, user interfaces, and deployment configurations. Built on ASP.NET Core with C for the backend and React for the frontend, it offers high performance with low latency and supports multiple database systems such as SQLite, PostgreSQL, SQL Server, and MySQL. The platform features a built-in Model Context Protocol server that enables seamless integration with AI agents like Antigravity, Cursor, and Codex, allowing developers to design data structures, write code, and deploy apps directly through chat interfaces. Users can generate applications via a browser-based tool for non-technical users, leverage AI-driven workflows for frontend development, or extend the system with custom plugins and endpoints for full-stack engineering needs. It includes a visual page designer using GrapesJS and provides REST and GraphQL APIs for robust data

FormCMS: The AI-Powered App Platform

FormCMS is an open-source platform that turns natural language into full-stack apps — schemas, APIs, UI, and deployment — in minutes. Ship with Docker, build with AI agents, scale to millions of records.

✨ Why FormCMS?

🤖 AI-Powered

Generate schemas, data, GraphQL queries, and full UI pages from natural language — in the browser or through AI agents.

🔌 MCP Server Built-In

AI agents (Antigravity, Cursor, Codex) connect directly via MCP to design schemas, seed data, and deploy apps — all from the chat window.

🚀 Scalable & Performant

P95 latency under 200ms, 2,400+ QPS throughput. SQLite, PostgreSQL, SQL Server, and MySQL supported.

🎥 In Action

Watch FormCMS build a complete Library system (Entities, Data, Queries, and UI) from scratch in under 60 seconds (sped up 10x).

🛠️ Build Full-Stack React Apps using AI Agents (MCP)

Learn how to connect different AI editors to the FormCMS MCP server to scaffold, build, and deploy apps without writing any backend code:

🛠️ Three Ways to Build

🌐 Beginners

No IDE needed. Open FormMate in your browser, describe what you want in plain English — AI generates your schemas, sample data, queries, and pages.

🎨 Frontend Developers

Build with AI agents. Connect Antigravity, Cursor, or Codex to the built-in MCP server — the agent designs your schema, writes your React app, and deploys it.

⚙️ Full-Stack Developers

Extend the platform. FormMate is Node.js (Fastify), FormCMS is .NET — fork the repo, add custom endpoints, write plugins, or integrate external services.

🗺️ Roadmap

FormCMS is actively evolving toward a vision of AI-native app development:

Phase Focus Key Features
Enhanced AI Smarter generation Natural language → schema, AI-suggested relationships, auto-generated CRUD & queries
Visual Builder No-code editing Drag-and-drop page builder, visual schema editor, real-time preview, theme templates
Marketplace Community ecosystem Pre-built app templates, community components, one-click install

The Vision: Describe your app in plain English → AI generates the entire backend → deploy with one click.
