Ollama

Ollama lets developers download, run, and build with open-source large language models either locally on their own computer or through Ollama's cloud service. It provides a command-line interface and an API for integrating models into applications and workflows, plus support for launching AI agents on top of those models. The platform highlights that it works fully offline once models are downloaded, and states that user data is never used to train models, which matters for developers who need to keep code or documents private. Ollama supports macOS, Windows, and Linux, and integrates with a growing set of developer tools, including Claude Code, OpenCode, VS Code Chat, OpenClaw, and Hermes Agent, letting models run through Ollama power coding agents and assistants inside familiar editors and terminals. The homepage highlights trending open models such as GLM, DeepSeek, and Kimi that users can pull and run with a single command. Ollama is built by Ollama Inc. and is aimed at developers and engineers who want control over which models they run and where the data goes, rather than depending on a single hosted API provider. One limitation is that running larger models locally still requires meaningful hardware, since model size and available memory directly determine what a machine can run well.
