You do not need to understand the whole Kestrel Suite before you begin. Choose the path that matches your immediate goal; each one reaches a useful result before introducing the deeper runtime concepts.
Run agents on your computer
Choose Kestrel Desktop when the work begins with files or repositories on your machine. The application keeps your workspace, conversation, run history, and operator decisions together so you can close it and continue later.
Download and install Kestrel Desktop
Continue work with a team
Choose Kestrel One when several people need to continue the same agent work with shared context and clear access controls. You will need an invitation from your Kestrel One organization administrator.
Start with your Kestrel One invitation
Add Kestrel to your product
Choose Build when you are adding durable agent execution to an application you already own. The first tutorial creates a typed agent, runs it through the SDK, and shows the human-facing response and structured result separately.
