Official app downloads and supported devices

A terminal coding-agent workspace designed around Ghostty, with local-model configuration alongside hosted providers. The MIT application is free; a cloud model or paid provider API can still incur its own usage charge.

Free MIT app; model and provider costs separate

The MIT command-line app is free. A local model path avoids paid inference, but model files, their own license, local compute and storage are separate. Hosted model providers can charge independently; Demesne does not include paid API credits.

Free software · local or paid model options

Use an AI coding agent in an editor or terminal, with an optional local model.

The Apache-2.0 Cline VS Code extension and CLI have no software license charge. Use local Ollama models without a paid API key or per-request model charge, on your own hardware. Cline usage-billing, ClinePass subscriptions and external cloud model providers are optional paid routes with their own terms. The current repository says its JetBrains plugin is not open sourced. This review establishes the local client route, not unlimited hosted inference.
