Best for a self-hosted chat interface for a team
Needs a server and a model backend such as Ollama. Source-available license with a branding clause for deployments over 50 users.
Best for an open-source desktop app with cloud options
Apache-2.0 desktop app. Cloud providers such as OpenAI and Anthropic need your own paid API key.

Right for specific needs, or not yet mature enough to recommend widely.
