01
Pick one repeated product or gallery path
Start with a product detail hero, gallery image, collection tile, lookbook image, avatar, or article hero that repeats across the site.

A Sirv alternative for testing image delivery before you change media workflows
Skymage is a focused comparison when the job is faster delivery for images you already publish. Keep the current public origin, generate exact URL variants, and prove one product, gallery, or editorial page before changing viewer, zoom, or media-library workflows.

When Skymage is a practical Sirv alternative
Use Skymage when the comparison is about delivery and transformation proof for existing images. Keep specialized zoom, spin, viewer, or asset-management workflows unchanged until one delivery path proves value.
| Need | Skymage test | What to measure |
|---|---|---|
| Existing image origin | Put the current host and path after /v1/ and request a first optimized variant. | Whether the image resolves, caches, and keeps the current publishing workflow intact. |
| Product image variants | Create PDP hero, listing thumbnail, and gallery variants with explicit size, crop, quality, WebP, and AVIF params. | Bytes saved, rendered fit, visual quality, and cache behavior. |
| Low-risk comparison | Test one page before replacing image viewers, zoom tooling, or media-management workflows. | Whether delivery-only improvement is enough to justify a broader rollout. |
| Expansion proof | Apply the winning URL pattern to nearby product, gallery, avatar, or editorial images. | How many repeated placements can use the same transformation pattern. |
proof path
Run a delivery proof before replacing the media stack
A useful Sirv alternative test should produce a narrow decision: keep the current workflow, use Skymage for one repeated delivery pattern, or expand to more image-heavy templates.
02
Generate delivery-only variants
Create one large image, one mobile-friendly image, and one cropped thumbnail without changing zoom, viewer, or CMS behavior.
03
Compare the measurable result
Review transfer size, rendered dimensions, cache behavior, visual quality, and LCP pressure before planning any wider migration.
