Projects let you organize your DigitalOcean resources (like Droplets, Spaces, and load balancers) into groups that fit the way you work. You can create projects that align with the applications, environments, and clients that you host on DigitalOcean.
The DigitalOcean API lets you manage DigitalOcean resources programmatically using conventional HTTP requests. All the functionality available in the DigitalOcean Control Panel is also available through the API.
You can use the API to create, delete, and manage projects.
doctl is a command-line interface for the DigitalOcean API and supports many of the same actions.
