The trac runtime

The trac runtime is a lightweight Python package that provides the execution framework for trac models. Install it once and the same model code runs identically across local development, notebooks, and production — with no modification and no environment-specific configuration.

The runtime is universal across analytic Python code, de-coupled from physical infrastructure, and compatible with all major cloud platforms, data formats, repositories, and development tools. Models are composable at runtime without hard-coded process logic.

The runtime is available standalone via PyPI and is the execution layer within the trac platform. See Modelling introduction for a full guide to building trac models, or install directly from pypi.org.
