Matterport or VPiX
If you're looking for a good alternative to Matterport, 3D Insider ranked VPiX as the #3 choice.
Cameras? With Matterport, you have three choices. (1) Their expensive boxy cameras or (2) the Ricoh Z1 or the (3) Insta360 ONE. With VPiX, you can your Canon, Nikon or Sony DSLR. You can use Insta360, QooCam, Ricoh Theta, Z1 or the Insta360 Pro, Pro II or their new Titan.
HDR Workflow. With Matterport, you can't use bracketing or any kind of HDR work flow post processing. This is why Matterport images can look soft, and have washed out windows.
With VPiX, you can use HDR processing work flows. (The crowd goes Yay!) We have a 2-day Denver VR Bootcamp that teaches you how to use HDR with your DSLR camera, or your Kdandao VR QooCam 8K, or the Insta360 Pro, Pro II or Titan 360 cameras.
Matterport images cannot be sharpened or post-processed before they move over to their platform. You can't create custom themes or remove Matterport's branding. If you're a property manager with more than 200+ listings, be prepared for expensive annual hosting. With VPiX, you can export your entire virtual tour and archive it off-line. No expensive annual hosting fees for hosting sold or inactive tours.
Copyrights are another issue. Matterport reserves the rights on the content you produce, and they can sell them to anyone.
VPiX offers white label branding. Matterport doesn't.
