Kompakkt review
A web-based viewer and repository for annotating, presenting, and sharing 3D collections.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Kompakkt brings browser-based 3D viewing together with a repository for exploring and sharing objects. It is aimed at communities that want to present 3D collections with context, rather than at users seeking a general-purpose 3D production environment. The vendor describes support for 3D models, point clouds, and Gaussian splatting models, and the product is open source and free. Collections provide a way to organize objects and collaborate with a community, making Kompakkt a fit for groups that want shared access to 3D material alongside explanations of what viewers are seeing.
Annotations are the most distinctive part of the experience described by the vendor. They can be tied to locations on an object and to camera perspectives, and can include text, images, audiovisual media, URLs, and other content. That gives a collection more interpretive depth than a viewer limited to displaying geometry. Consecutive annotations can also form a walkthrough, guiding viewers through an object from different perspectives. This presentation approach suits educational, cultural, or community collections where a guided reading of an object matters as much as the model itself.
Sharing has both public and private options: default annotations can be visible to others, while private annotations are made through collections. The product is web-based, so its stated access model is browser viewing rather than a named desktop platform. Choose Kompakkt when open-source viewing, spatial annotation, walkthroughs, and community collections are central to the job. It is a less natural fit for buyers prioritizing production tools or needing a viewer selected around specific file-format requirements; the published product description focuses on viewing and curation.
