Openinary is an open-source alternative to Cloudinary. Upload your media, then transform it on demand via URL, resize, crop, convert formats, trim video, and more. Runs anywhere Docker runs. Prefer not to run it yourself? Openinary Cloud is the hosted version, same API, no server to manage. It’s currently in early access.
