 A **browser profile** is a saved snapshot of browser state — cookies, localStorage, and session files. Load a profile into a new [browser session](/cloud/browser-management/browser-sessions) and the browser starts with that saved state restored, skipping login flows you've already completed.

 A **browser session** is a live browser instance that stays open between runs. Cookies, login state, cart contents, and page context all persist — like keeping a browser tab open. Use sessions when you need back-to-back tasks to share state, or when you want to interact with the browser yourself between automated steps.
