| imgproxy | On-demand transformations, production-proven | Apache-2.0 |
| Openinary | Uploads, transformations, and media browser (young) | AGPL-3.0 |
We looked for open-source tools that transform and deliver images through URLs like ImageKit. We verified each project's license, recent activity, stars, and self-hosting in its repository. Neither includes a global CDN. See our methodology for the full criteria.
imgproxy resizes, converts, and optimizes images on demand through URL parameters, with AVIF and JPEG XL support, signed URLs, and image bomb detection. Object detection, SSIM-based auto-quality, and video or PDF previews require the paid Pro version.
Openinary is a media platform for uploads, transformations, and delivery on your own S3-compatible storage such as R2, MinIO, or GCS, with Cloudinary-compatible URLs and a media browser. Its managed cloud is in public alpha, and the project is young.
imgproxy is Apache-2.0. Openinary is AGPL-3.0.
