Dropbox vs Filestack

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.

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.
