ChatOSS

The desktop app for Ollama. Chat, code, and plan with your local models — and scale to faster cloud models when you need them. Free local use, no account required.

Built for agentic coding

ChatOSS is a native desktop workspace where AI agents do real work alongside you. They write code in your repos, plan and track tasks on an integrated Kanban board, and ship. It's more than chat — a suite of apps you can extend, running on Ollama or the cloud.

• Agents that work directly inside your repositories
• Integrated Kanban board — plan and ship with a team of agents
• A growing suite of apps, and you can build your own
• Bring models from Ollama or the cloud, and switch anytime

Use the open source models you love

ChatOSS brings your favorite open source AI models together in one place — chat with them, code with them, and put them to work side by side. Run them on Ollama for free, or scale up to cloud versions when you need more.

• Qwen, DeepSeek, GLM, Minimax, Gemma, and more
• Bring your own local models via Ollama
• Switch models mid-conversation, no restart
• Run many agents in parallel on the models you choose

Use ChatOSS free forever with local models

Local Ollama models run entirely on your machine — no account, no credit card, no limits. Install and go.
