ChatForge: Open-Source RAG Chatbot Framework

Ship a production RAG chatbot in minutes — no code, no fine-tuning.

Introduction

ChatForge is an extensible, open-source framework for building retrieval-augmented chatbots that answer questions from product catalogs, documents, and FAQs — all through natural conversation. It pairs Pixeltable for vector search with Chainlit for the chat interface, and supports multiple LLM backends so you're never locked in. The goal: take a pile of unstructured knowledge and turn it into an intelligent assistant in under ten minutes.

Demo

The demo

Built a fully functional customer support agent for Bombay Shaving Company in under 10 minutes — no code, no fine-tuning. The agent answers real customer questions grounded entirely in the brand's own catalog and FAQs.

Key Features

• Vector search with Pixeltable — fast, incremental retrieval over your knowledge base.

• Chainlit chat UI — a polished conversational interface out of the box.
