What are you building?
Connectivity
Connect Speckle to or from desktop hosts, enterprise systems, or automation pipelines
(connectors, add-ins, ETL, middleware).
Applications
Products on Speckle: web apps, embedded viewer, dashboards, Automate, and server deployment.
How Speckle stores model data
A version’s data is a bundle: properties in a columnar store, and containment, connectivity, systems, and materials as typed relations. Versions published before 2026.9 use a tree-and-Proxy object graph instead, described in the Data Schema. Both can exist in one project, so check which format a version uses before you read it.Object model
Columnar property store and relational layer, and how they differ from the object graph.
Relations
Named relation types that replace Proxies and nested
elements walks.What Can You Build?
On Speckle (platform):- Custom applications — Web apps, visualizations, and tools using the viewer and data APIs
- Automate workflows — Serverless functions that process model data when new versions arrive
- Self-hosted server — Deploy and customize your own Speckle server instance
- Connectors and host add-ins — Send and receive between Speckle and CAD/BIM/structural applications
- Pipelines and middleware — Sync Speckle with databases, PLM, scheduling, or proprietary APIs
