Harbor: Enterprise B2B Design System

Web · Light · Minimal · SaaS

Harbor

Navy, white space and steady structure for serious B2B products.

Harbor looks dependable without looking dull: a cool blue-grey page, navy for the main action, a bright blue for focus and data, and Plus Jakarta Sans for a modern but sober voice. Long feature pages, comparison tables and security sections fit with ease.
