Local AI-powered full-stack app builder with privacy and cost control
December lets you generate complete Next.js applications from natural language prompts, running locally in Docker with your own LLM API keys for full privacy and reduced expenses.
December targets developers, hobbyists, and educators who want AI-assisted full-stack coding without sending their code to the cloud. By running locally, it guarantees data privacy and lets users control LLM costs with their own API keys.
From a simple text prompt, December generates a complete Next.js project, packages it in Docker, and opens a live preview with mobile and desktop views. An integrated Monaco editor lets you edit files, while a real-time chat assistant offers coding help. Projects can be exported or deployed directly from the environment.
Clone the repository, add your preferred LLM credentials in config.ts, install Docker, and run sh start.sh. The backend runs on port 4000 and the frontend on 3000, ready for immediate development.
When teams consider December, these hosted platforms usually appear on the same shortlist.

Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Rapid prototype from an idea
Turn a brief description into a runnable Next.js prototype in minutes.
Learning full‑stack development
Generate a complete codebase and explore its structure using the built‑in editor.
Bootstrapping a startup MVP
Create boilerplate with essential pages and APIs, then customize locally.
Offline development in restricted networks
Work entirely on a local machine without external cloud services.
Any OpenAI‑compatible provider such as OpenAI, Anthropic Claude, Ollama, or OpenRouter. Configure the base URL and API key in `config.ts`.
An internet connection is required to call the external LLM API, but the development environment itself runs locally.
Yes, December includes project export functionality and you can deploy the Dockerized app to any container platform.
No. All generated code and project files remain on your local filesystem unless you choose to upload them yourself.
Docker (Desktop or Engine) installed, a compatible LLM API key, and a recent version of Node.js for the scripts.
