LibreChat

What it is

LibreChat is a web chat app modeled on the ChatGPT interface that connects to many model providers, including OpenAI, Anthropic, Google, AWS Bedrock, Azure, and local runners like Ollama, and lets users switch models mid-conversation. It adds no-code agents with MCP tools, skills, file search, a sandboxed code interpreter, web search, code artifacts, and image generation. Teams and individuals run it on their own servers to give multiple users authenticated access to AI models while keeping conversations under their control.
