Filestack vs Gyazo

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.

Gyazo is a screenshot and screen-capture sharing service whose API lets apps upload images and GIFs and fetch a user's capture history. A live GET against the real gateway, api.gyazo.com/api/images, returned a 401 without a token, reconfirming API-key auth over HTTPS, and a follow-up OPTIONS preflight returned Access-Control-Allow-Origin: *, resolving cors from unknown to yes. The free tier covers everyday screenshot sharing, while a paid Gyazo Pro plan adds unlimited uploads, higher-res captures, and privacy controls.
