Welcome to Speckle’s Developer Documentation! Here you’ll find everything you need to build on Speckle or connect Speckle to other applications and systems.

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.

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
With Speckle (connectivity):
  • 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
Shared foundation for both tracks: Authentication, GraphQL API, Data schema, and SDKs.
