Summary

Image Foundry matches Sirv on all core image processing features: resize, crop, format, quality, effects, overlays, watermarks, text, and face detection.
Sirv specialises in 360° spin views, media viewer (zoom/pan), and video hosting — features outside Image Foundry's scope.
Image Foundry adds duotone, sepia, pixelate, colour palette extraction, face blur/pixelate, and blend modes that Sirv doesn't offer.
Image Foundry's advantages: open source (MIT), self-hosted, no vendor lock-in, multi-tenancy, dual URL format support.
