No. It resizes and serves. Uploads and a media library stay in your app or Nextcloud. Cloudinary bundled those; this stack does not.

Stacks / Backend

Easy

imgproxy / Thumbor / Imagor

Image transforms you host. imgproxy OSS is MIT; Thumbor is MIT; Imagor is Apache-2.0 — Cloudinary without the credit pack.

The problem

Cloudinary Plus is $89/month for 225 credits; Advanced is $224/month billed yearly. You wanted resize, format, and a URL. imgproxy's open-source edition is MIT (Pro processors are paid — skip them). Thumbor is MIT. Imagor is Apache-2.0. You still need object storage and a CDN in front.

Agent setup prompt

Replace Cloudinary URL transforms with imgproxy (preferred), Imagor, or Thumbor.

- Point the proxy at S3/MinIO or a volume of originals. Bind HTTP to 0.0.0.0:$PORT. Sign URLs.
- Do not enable imgproxy Pro features without a license. Video transforms are not the OSS path.
- Swap one Cloudinary URL for a proxy URL. Write AGENT_PROMPT.md.
