Node-RED - free open source tool for wiring things together

Node-RED is an open-source programming tool for wiring together things in a new and interesting way. Things are hardware devices, APIs, online services etc.

Further Node-RED provides a browser-based editor that eases wiring together flows using a wide range of nodes given in the palette that is deployed to its runtime in a single-click.

In the Internet of Things (IoT) world we want to connect things together. However, sometimes they were not meant to be connected. Node-RED makes this fast and easy.

EVOCEAN developed a Things Execution Framework (TXF) for IBM Rational Rhapsody, such that you can wire the things easily on the fly together with Node-RED. Thus, empowering Model Execution and wiring. You can read more about this on the  ConDisSca product page.

Node-RED Functionalities

Brower-based flow editing

Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range of nodes in the palette. Flows can be then deployed to the runtime in a single-click. Furthermore, JavaScript functions can be created within the editor using a rich text editor. A built-in library allows you to save useful functions, templates or flows for re-use.

Build on Node.js

The light-weight runtime is built on Node.js, taking full advantage of its event-driven, non-blocking model. As a result this makes it ideal to run at the edge of the network on low-cost hardware such as the Raspberry Pi as well as in the cloud. With well over 2oo,000 modules in Node’s package repository, it is easy to extend the range of palette nodes to add new capabilities.

Social Development

The flows created in Node-RED are stored using JSON which can be easily imported and exported for sharing with others. Further, an online flow library allows you to share your best flows with the world.

Getting Started

Node-RED is built on Node.js, taking full advantage of its event-driven, non-blocking model. This makes it ideal to run at the edge of the network on low-cost hardware such as the Raspberry Pi as well as in the cloud.

Run locally, on a device or in the cloud.

Customers about our services

Mettler Toledo AG

„Now the advantages of our solid foundation work will have a large impact. A model is easy to adapt and maintain and new functions can be integrated very fast. In combination with the automatic code generation and testing we now will be strikingly faster… with a consistent high quality. Today we save time and money – not least thanks to IBM Rational Rhapsody!"

Wolfgang Boos

Head of Software

Bernina International AG

„Die Architektur muss von Anfang an richtig aufgesetzt werden und den Voraussetzungen einer modellgetriebenen Entwicklung entsprechen. Ich empfehle jedem Unternehmen, sich Unterstützung von einem externen, erfahrenen Rhapsody Spezialisten wie beispielsweise EVOCEAN zu holen, um die Basisarchitektur gemeinsam zu modellieren.“

„Development in the embedded area should be platform independent and the used tools should support this!“

Kern AG

„Even if the change to Rhapsody required at first additional investment and effort – we have never regretted our decision. The fully automatic code generation from the model makes our life easier!“

Andreas Dubach

Head of Development Systems

MCS Engineering AG

"It is very easy to set up and run a Perforce Helix Core proxy server for working with geographically dispersed teams. Downloading data is also very easy. We were amazed at how much time we saved."

Eric Gutmann

Project Leader


"Ein grosses Lob an den sehr motivierten Trainer. Der Trainingsinhalt wird sehr kurzweilig und auch unterhaltsam vermittelt. Methodisch sehr gut war auch die jeweiligen Trainingstage am Ende nochmals Revue passieren zu lassen. Frank Braun konnte auch jede Frage beantworten und hat auch versucht, sofern der zeitliche Rahmes es erlaubte, auf angesprochenen Themen einzugehen."

„We would repeat our decision to choose Rhapsody® at any time. The strikingly improved efficiency, higher quality, and flexibility plus reusability of models make any adverse details negligible. Today we develop more machines with fewer resources in less time."

Reinhold Wüstner

Head of Product Development

Bernina International AG

„Thanks to the models we can visualise new functions and dependencies. A picture says more than a 1'000 words and the graphically modelled abstraction makes life much easier for us developers. At the same time, the automatic code generation based on the models takes over a substantial part of our work!“

Rhapsody Training Feedback

The trainer was very well prepared, has an excellent overview and deep knowledge about the tool and about our surrounding processes (A-Spice) and methods.

A warm praise to the very motivated trainer. The training content is conveyed in a very enjoyable and entertaining way. It was also very good to review the respective training days at the end. Frank Braun was able to answer every question and also tried, as far as time allowed, to address further topics raised.
