Switching Cost
Cloudinary's lock-in is the URL transformation API. If your frontend uses Cloudinary URLs with transformation parameters (/w_400,h_300,c_fill/), every image reference needs updating. Your original assets download via API. Teams with a few hundred images can migrate in a day. Teams with thousands of images referenced by Cloudinary URLs across their codebase should budget a week to update all references and test. The hidden cost is the CDN: Cloudinary serves images from edge locations with automatic format negotiation (WebP for Chrome, AVIF for newer browsers), and replicating that requires a CDN plus an image processing service.
