PROOF – PROcess Orchestration Framework

Links

PROOF is an open-source co-simulation framework that allows users to create and orchestrate complex workflows. It features a containerized approach which ensures platform-independent usability across Linux, Windows, and macOS.

The PROOF UI provides a user-friendly, web-based interface for creating, managing and monitoring workflows. It features a drag‑and‑drop editor, real‑time logs, and automated status updates, allowing users to build reproducible pipelines without writing code.

The full documentation can be found at https://kit-iai-proof.github.io/, the code can be accessed in Github.
