Overview
NextChat is a Node.js web client (Docker image yidadaa/chatgpt-next-web on port 3000, or a one-click Vercel deploy) that talks to OpenAI, Azure, Anthropic, Google Gemini, DeepSeek, Baidu, ByteDance, Alibaba, iFlytek, ChatGLM, SiliconFlow and 302.AI through environment variables. Chat history stays in the browser, access is gated by a shared CODE password list, and MCP tools switch on with ENABLE_MCP=true.
Who it is for: Individuals who want a fast single-container chat front end for API keys
Strengths
- First screen about 100 KB with streaming responses; desktop client about 5 MB
- Providers configured purely by environment variables; CUSTOM_MODELS edits the model list
- UI in 14 languages; PWA, dark mode, Markdown with LaTeX and mermaid
- Hosted demo at app.nextchat.club
Weaknesses
- No user accounts; access control is a comma-separated password list in CODE
- Conversations live in browser storage; cross-device sync needs an UpStash setup
- OPENAI_API_KEY is marked required even when another provider is used
- Local knowledge base still unchecked on the roadmap
What it needs
- no GPU
- Docker + Compose
- Models: OpenAI, Azure OpenAI, Anthropic, Google Gemini, DeepSeek
- port 3000
