## What it is
AgentKit is a full-stack starter kit from BCG X for building constrained, chat-based LLM agent applications using Next.js/React on the frontend and FastAPI with LangChain on the backend. It ships with a reactive chat UI (streaming, tables, visualizations, agent action status) plus production-oriented scaffolding like queue management, auth, caching, and monitoring. The repository is now deprecated and no longer actively maintained.

## Use cases
- build a chat-based AI agent app with a full-stack template
- prototype a constrained agent architecture with a nice UI quickly
- spin up a GenAI proof-of-concept chatbot in hours
- create a production-grade MVP agent app with auth, caching and monitoring
- experiment with LangChain agents using FastAPI and Next.js
- demo an agent that streams responses and renders tables and code

## When to choose
- you want to study or fork a well-structured full-stack agent starter kit
- you need a quick internal demo of a constrained LangChain agent with a polished chat UI
- your team already commits to maintaining the forked codebase yourself

## When to avoid
- starting a new project, since the repo is deprecated and unmaintained
- you need long-term support, security patches, or up-to-date LangChain/OpenAI integrations
- you want a non-chat or highly custom agent runtime
- you prefer actively maintained alternatives like the Vercel AI SDK chatbot template or the FastAPI full-stack template
