This project provides a no-code toolkit for building and hosting AI chatbots, leveraging LangChain. It targets users who want to create custom chatbots with external data, plugins, and custom authentication without extensive coding. The primary benefit is rapid deployment of conversational AI interfaces.

How It Works

LangChain UI is built on Next.js 13 with Chakra UI and Prisma. It utilizes a backend API (migrated from TypeScript to Python) to manage chatbot logic and interactions. The architecture allows for custom data sources, authentication providers (defaulting to GitHub), and provides dedicated API endpoints for each chatbot, enabling embedding into other applications.

Quick Start & Requirements

• Install: npm install
• Prerequisites: Node.js, npm, a GitHub repository (fork or clone), .env file configured from .env.example.
• Run: npm run dev
• Docs: https://github.com/homanp/langchain-ui

Highlighted Details

• No-code interface for chatbot creation.
