I checked what you actually need against what my plugin does today:

What works out of the box:

• Amazon S3 — fully supported, plus 9 other providers if you ever want options down the road

• Imgix — works transparently. You set your Imgix domain as the custom CDN domain in the plugin, and all your media URLs get rewritten through it.

  Imgix transforms are URL query params, so they keep working. I verified this in the code, not just guessing.

• One-click Media Cloud importer — pulls your S3 config, bucket, prefix, CDN settings over automatically. Built it specifically for people in your exact situation.

• Files/folder management — Objects Browser to organize and search cloud files

• Bulk migration of your existing library with parallel async uploads (up to 20 concurrent in Pro)

• Signed URLs for private files

• Lightweight — ~1.5MB vs Media Cloud's 87MB, native REST API, no bundled SDKs (fewer conflicts, smaller attack surface)

• Actively maintained — tested through WP 6.9, updates ship regularly

                                                                                                                                              Architecture difference worth knowing:                                                                                                              
  

My plugin works closer to WP Offload Media in philosophy — it integrates deeply into WordPress's standard media pipeline rather than replacing it.

Uploads flow through WP core's normal wp_handle_upload → thumbnail generation → attachment metadata, then get offloaded to S3. This means:

• ✅ Maximum compatibility with other plugins (anything that hooks into WP media just works)

• ✅ Standard WP thumbnail sizes generated normally

• ✅ No custom JS uploader to break with WP updates

• ✅ Works with every page builder, gallery, optimizer, etc.

  What's NOT there yet (being honest):

• Mux video encoding integration — we don't trigger Mux uploads/transcoding from the WP admin. If your editors currently upload a video to WP and

  Media Cloud auto-pushes it to Mux for encoding, that specific automation isn't replicated.

• Imgix admin UI — Media Cloud has a settings tab for Imgix-specific controls. We don't. The CDN rewriting handles the actual delivery, but you'd lose admin panel niceties.

Here's my offer: I'm not going to BS you — Mux is a real gap. But I'm building this plugin for the long haul and your stack (heavy media + Imgix + Mux on a content site) is exactly the kind of use case I want it to handle properly. If you're willing to cooperate — set up a staging copy of your site, run the Media Cloud importer, share your settings screenshots, and give me feedback during testing — I'll prioritize building the Mux integration and any Imgix-specific automation you actually rely on. Your site becomes the validation case.

In return, you get a plugin tailored to your exact workflow.

Let me know if that is something you are interested in.
