ChatBot UI
Chatbot UI: Open-Source ChatGPT Interface Clone
Chatbot UI is a free, open-source interface that replicates ChatGPT's look and feel, letting you chat with OpenAI's models using your own API key.
Overview
Chatbot UI is a developer-friendly, open-source project built to recreate the familiar ChatGPT experience while giving users full control over their own OpenAI API connection. Rather than relying on OpenAI's hosted product, you bring your own API key and get a near-identical interface for chatting with GPT models, complete with conversation history and customizable settings.
Because it's completely unaffiliated with OpenAI and purely communicates through the official API, Chatbot UI appeals to developers, researchers, and AI tinkerers who want a transparent, customizable front-end without vendor lock-in. Its open-source nature means anyone can inspect the code, self-host it, tweak its behavior, or extend it with new features to fit specific workflows or experiments.
