Pixie
Pixie is a visual app builder that streamlines the creation of interactive mini-apps through a three-step workflow: importing tools from MCP servers or OpenAPI specifications, designing custom widget UIs with an intuitive interface, and deploying them as standalone applications. Built with Python FastAPI backend and React frontend, it features comprehensive tool management, widget chat functionality with LLM integration (OpenAI/Claude), database persistence via Supabase, and deployment capabilities including OpenAI Apps SDK compatibility for ChatGPT integration.
