December is an open-source, local-first alternative to AI-powered development platforms like Replit and Bolt, enabling users to build full-stack applications from natural language prompts. It targets developers seeking privacy, cost savings, and full control over their projects, offering a fully containerized Next.js development environment.

How It Works

December leverages AI models (via OpenAI-compatible SDKs) to translate natural language prompts into containerized Next.js applications. It utilizes Docker for environment management, providing a live preview with mobile and desktop views, a Monaco code editor, and an integrated chat assistant for development help. This approach offers a self-hosted, private, and cost-effective development workflow.

Quick Start & Requirements

• Install via git clone https://github.com/ntegrals/december.
• Requires Docker and an OpenAI-compatible API key (e.g., OpenAI, Claude, Ollama, OpenRouter).
• Configuration involves setting the API key and model in config.ts.
• Run with sh start.sh.
• Access at http://localhost:3000.
