Build me a platform for creating and managing AI applications. It should be a web app with a nice visual interface where you can design AI workflows, almost like a drag-and-drop or no-code tool. I want users to be able to connect to various LLM providers like OpenAI, Mistral, and Llama3 just by plugging in their API keys.

A key feature should be building RAG pipelines. This means I want to be able to upload my own documents—like PDFs or other files—and create a chatbot that can answer questions based on that specific content. The platform should also allow for creating AI "agents" that can use tools to perform tasks. Essentially, I'm looking for a self-hosted, open-source alternative to tools like Dify, where someone with light technical skills can prototype and deploy AI apps and workflows.
