An open-source data platform for AEC that streams and versions BIM data between different software (Revit, Rhino, Grasshopper, Blender) without exporting static files each time. Instead of exporting an IFC or Navisworks file and re-importing it whenever something changes, Speckle keeps live, versioned "streams" of model data that different tools can push to and pull from - closer to how a code repository works than a traditional file exchange. It's gained traction as a lighter, more automatable alternative to file-based interoperability, especially for teams already scripting with Dynamo or Grasshopper.
