Ollama is a command-line tool and local server that manages open-weight language models on the machine it runs on. It ships a CLI, a REST API on port 11434, and client libraries for Python and JavaScript, so the same model can be driven from a terminal, a script, or an existing agent framework. Model execution is handled by the llama.cpp backend, and the project distributes installers for macOS, Windows and Linux alongside an official `ollama/ollama` Docker image.

Open WebUI is a self-hosted, open-source AI interface that unifies access to local and cloud-based large language models. It runs entirely in a web browser and supports Ollama for local model hosting alongside any OpenAI-compatible API, including services like LMStudio, GroqCloud, Mistral, and OpenRouter. Built in Python, it functions as a drop-in replacement for proprietary AI platforms, giving users full control over their model infrastructure and data.

LibreChat is an open-source, self-hostable chat interface designed as an enhanced ChatGPT clone. It unifies access to multiple AI models—including OpenAI, Anthropic, Google Gemini, DeepSeek, Mistral, AWS Bedrock, Azure OpenAI, and others—within a single web application. Built in TypeScript, it supports real-time streaming, multi-model switching, and advanced agent workflows while providing features like message search, artifacts, code interpreter, and secure multi-user authentication.
