Distributed coordination scenarios place high demands on concurrency and interaction. They are therefore a typical source of errors in design and implementation. The Peer Model is a modeling tool for coordination based on blackboard-based collaboration. Its goal is to help developers of coordination software better understand algorithms and identify deficiencies from the beginning. This paper describes the open source implementation of the Peer Model tool-chain, which is made available on GitHub1 and Zenodo2 including a tutorial video published at YouTube3 and Zenodo4. The tool-chain consists of a modeler, translator and simulator.
