Viash

From scripts and metadata to a modular data pipeline.

  • Viash uses code generation to create a module from your script that can be used seamlessly in a data pipeline
  • Built-in interfaces for inputs and outputs makes linking modules in a pipeline trivial.
  • Focus on the functionality of your script, Viash will take care of the data workflow framework.
  • No expert knowledge needed – our automatic wrapping makes for high quality code.
