Box vs Filestack

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.

Filestack is a file-upload and processing API that handles ingestion from local disk, cloud drives, and URLs, plus on-the-fly transformations like image resizing and document conversion. A live POST against the real gateway, www.filestackapi.com/api/store/S3, returned a 400 without a valid key, reconfirming API-key auth and HTTPS, and a follow-up OPTIONS preflight echoed the request Origin in Access-Control-Allow-Origin, resolving cors from unknown to yes. Filestack starts with a free plan for low-volume use and scales into paid Growth, Pro, and Enterprise tiers as upload and processing volume grows.
