## The short answer **ChatGPTNextWeb/NextChat** (88,588 stars, TypeScript) is a light and fast AI assistant UI. It started as a ChatGPT web wrapper and grew into a cross-platform app covering Web, iOS, MacOS, Android, Linux, and Windows - all from one codebase. You bring your own API key and it works. ## Highlights - **One-click deploy**: Vercel, Docker, or a static export - **Multi-provider**: OpenAI, Claude, Gemini, DeepSeek, and any OpenAI-compatible endpoint - **Cross-platform**: desktop apps for all major OSes via Tauri - **Prompt library**: built-in prompt management and sharing - **Local-first**: conversations can be stored locally or in the cloud of your choice ## Deploy in one command (Docker) ```bash docker run -d -p 3000:3000 \n -e OPENAI_API_KEY=sk-... \n --name nextchat \n yidadaa/chatgpt-next-web ``` Open http://localhost:3000. You can also deploy free on Vercel by importing the repo and setting the API key in environment variables. ## Configuring local models Set `OPENAI_API_KEY` to any key and add a custom endpoint: ```bash -e BASE_URL=http://localhost:11434/v1 \n-e OPENAI_API_KEY=ollama ``` Then pick a model like `qwen2.5:7b` in the settings and start chatting with your local LLM. ## Practical tips - Set `CODE` (access password) if you expose it publicly. - Use the built-in prompt store to keep frequently used prompts organized. - The desktop app (download from the releases page) gives you a native window on Windows/macOS/Linux. ## FAQ **Is it free?** Yes - MIT licensed; you pay only for model API usage. **Does it need a database?** No - it is stateless; conversations are stored in browser storage or via optional services. **Can it use Azure OpenAI?** Yes - there are settings for Azure endpoints and deployment names.
