A few useful answersDECODE

THE DETAILS.
Do I choose the model?＋
Yes. REX supports cloud providers, local runtimes such as Ollama, and custom OpenAI-compatible endpoints. Configure your provider in the agent.
Does local-first mean fully offline?＋
Your workspace and execution live on your machine. Cloud models and web tools still need a network connection. Local models can keep inference on your own hardware.
Can I use REX in my terminal?＋
Yes. Install @rxdsec/rexcli globally with npm and start it with rex. The CLI includes browser tools, queue controls, and automatic updates from version 0.3.11.
Where do I start?＋
Visit Downloads for the desktop builds or the CLI install command, then connect your model provider. Account access and plan details are explained on the Plans page.
