Overview
Manyfold is an open-source, self-hosted digital asset manager purpose-built for 3D printing model files. It automatically indexes STL, 3MF, and OBJ files, generating thumbnails, previews, and searchable metadata for large model libraries.
The project is maintained as a community effort on GitHub, built with Ruby on Rails and released under the AGPL-3.0 license, with no company or paid tier behind it.
Key Features
Manyfold automatically scans a folder of 3D print files, extracting metadata like dimensions and polygon counts, and presents them with thumbnails, tags, and full 3D previews in a searchable web interface.
It supports public or private sharing of content and can federate with other Manyfold instances or the wider Fediverse, letting users follow and discover models across separate self-hosted instances.
Pricing
Manyfold is completely free and open source, with no license fee, subscription, or paid tier. It is distributed as a multi-platform Docker image for self-hosting.
There is no official managed cloud version; the only cost is whatever hosting infrastructure a user runs, such as a home server, NAS, or small VPS, and a public demo instance is available for evaluation.
Key Features
Automatic model indexing — Point Manyfold at a folder of STL/3MF/OBJ files and it automatically indexes and catalogs them.
3D previews and thumbnails — Generates browsable 3D previews and thumbnails for every indexed model.
Metadata extraction — Extracts dimensions, polygon counts, and other metadata directly from model files.
Tagging and search — Organize and find models quickly with tags and full-text search.
Public and private sharing — Share individual models or collections publicly or keep them private.
Fediverse federation — Follow content on other Manyfold instances or across the wider Fediverse.
Docker deployment — Distributed as a multi-platform Docker image for easy self-hosting.
Home-lab platform support — Available via community install scripts for Unraid, Cloudron, and Proxmox VE.
