Filestack vs Google Drive

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.

Google Drive's API lets applications create, read, update, and share files and folders stored in a user's Drive, with fine-grained OAuth scopes for personal or Workspace accounts. A live GET against the real gateway, www.googleapis.com/drive/v3/files, returned a 403 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 url was updated to Google's current Workspace documentation hub, which the old /drive/ path now permanently redirects to. Personal accounts get 15GB free, with paid Google One and Workspace plans raising the storage cap.
