## What it is
ChatJS is an open-source, production-ready AI chat application built with Next.js and TypeScript, offering authentication, 120+ models via multi-provider gateways, streaming, and built-in tools like web search, image generation, and code execution. It is scaffolded via a CLI and can be deployed as a web app or packaged as a native desktop app with Electron.

## Use cases
- build a custom ai chatbot app
- self-host a chatgpt alternative
- create an ai chat app with multiple llm providers
- add streaming ai chat with auth to my product
- fork a production-ready chat ui instead of building from scratch
- package an ai chat app as a desktop application
- compare responses from claude gpt and gemini side by side

## When to choose
- you want to launch an AI chat product quickly without rebuilding auth, streaming, and persistence
- you need multi-provider model access (OpenAI, Anthropic, Google, xAI) through one interface
- you want built-in features like conversation branching, sharing, attachments, and MCP support
- you prefer a modern type-safe Next.js stack you can customize

## When to avoid
- you need a simple embeddable chat widget rather than a full application
- you are not comfortable with the Next.js/TypeScript/PostgreSQL/Redis stack
- you require fully managed hosting with no self-hosting or deployment work
- your use case is a non-chat LLM task like batch processing or fine-tuning
