langchain-ui and langchain-supabase-website-chatbot
These are ecosystem siblings—one is a general-purpose LangChain UI framework for building chat applications, while the other is a specific implementation template showing how to integrate LangChain with Supabase and Next.js for website chatbots.
About langchain-ui
homanp/langchain-ui
🧬 The open source chat-ai toolkit
⚠️ **Note: This project is unmaintained.** The maintainers have moved to [Superagent](https://github.com/homanp/superagent). --- Built on LangChain, this no-code interface enables deploying custom chatbots with external data sources, ChatGPT plugins, and configurable prompts—each with a dedicated API endpoint. The frontend uses Next.js 13 with Chakra UI and Prisma, while agent functionality delegates to a separate Python backend (LangChain UI API) for enhanced capability parity. Supports custom authentication providers, usage quotas, and multi-site embedding with themeable interfaces.
About langchain-supabase-website-chatbot
mayooear/langchain-supabase-website-chatbot
Build a chatgpt chatbot for your website using LangChain, Supabase, Typescript, Openai, and Next.js.
Implements automated web scraping with customizable CSS selectors to extract and embed website content into Supabase's pgvector extension, enabling semantic search via OpenAI embeddings. The chatbot leverages LangChain's retrieval-augmented generation (RAG) pattern to ground responses in your site's actual content, with a Next.js frontend handling real-time chat interactions. Setup requires configuring target URLs and content extraction rules, then running a batch embedding script before deploying the chat interface.
