Box vs Dropbox

Box is an enterprise content-management platform offering secure file storage, sharing, and collaboration, with a REST API and SDKs for building custom document workflows. A live GET against the real gateway, api.box.com/2.0/users/me, returned a 401 without a token, reconfirming OAuth 2.0 bearer auth over HTTPS, and a follow-up OPTIONS preflight returned Access-Control-Allow-Origin: *, resolving cors from unknown to yes. Personal accounts get 10GB free, while paid Business and Enterprise plans (plus metered Box Platform usage) unlock larger storage and API-driven workflows.

Dropbox is a cloud file-storage and sync platform, and its API lets apps read, write, and share files and folders in a user's Dropbox account. A live POST against the real gateway, api.dropboxapi.com/2/users/get_current_account, returned a 400 without a token, reconfirming OAuth 2.0 auth over HTTPS, and a follow-up OPTIONS preflight echoed the request Origin in Access-Control-Allow-Origin, resolving cors from unknown to yes. The free Basic plan includes 2GB of storage, with paid Plus, Professional, and Business tiers raising the cap and adding team features.
