Visual Programming
Node-RED offers a flow-based development interface which allows users to create applications by wiring together pre-built nodes, making it intuitive and easier to understand, especially for non-programmers.
Extensibility
The platform is highly extensible with a large library of pre-built nodes available and support for creating custom nodes. This makes it adaptable to a wide range of use cases.
Event-Driven
Node-RED is designed around an event-driven architecture, which is beneficial for handling asynchronous events and real-time data.
Cross-Platform
Node-RED is based on Node.js and runs on various platforms including Windows, macOS, Linux, and even low-resource devices like Raspberry Pi.
Integrations
It offers extensive integration capabilities with various protocols (like MQTT, HTTP, and WebSockets) and a wide variety of services (like databases, cloud services, and IoT platforms).
Node-RED is generally considered a good tool, particularly for non-programmers and those looking to quickly prototype and deploy IoT solutions. Its visual interface simplifies the development process and can handle a wide variety of integration tasks.
We have collected here some useful links to help you find out if Node-RED is good.
Check the traffic stats of Node-RED on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Node-RED on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Node-RED's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Node-RED on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

Node Red is a unique application that provides a graphical programming environment. With this, you can define input to output transformation with any level of complexity, including reading, parsing, formatting, and output with optional conditionals. For example, here is a flow definition that parses MQTT JSON messages that communicate if a node is alive, and then store this information in InfluxDB:. - Source: dev.to / 10 months ago
For a simple test, I created this Node Red flow that listens to homeassistant/status messages. HA itself will send messages that communicate when its started or when it is about to shutdown. These messages, and a custom message I send from within HA, could be seen:. - Source: dev.to / 10 months ago

During a college project in the field of IoT, I came across a simple and powerful solution for wiring together hardware devices called NODE-RED developed originally by IBM. The project was very simple as it only involved controlling electrical appliances and sensing room temperature using a temperature sensor. The whole hardware system was connected to the network using the MQTT Protocol, and using Node-Red, it... - Source: dev.to / about 1 year ago
Good question. I expect that we're moving into a phase of AIs talking to AIs, and initially it'll be wasteful (because it'll be mostly English), but eventually, they'll derive their own language and seamlessly upgrade protocols when they determine they're talking to an AI. No clue how that will come about or what that language will look like, but honestly, it's kind of exciting. Really interesting to think about... - Source: Hacker News / over 1 year ago

I skipped to chapter 9 in the article ("Clogged"), and it looked like Pipes failed because it didn't have a large enough team or a well-defined mission.

I believe Node-RED (https://nodered.org/) the way to go. It's just an NPM package to install and you can run it how ever you wish (even on Windows).

Does anyone know if their are plans to implement something like this (or if there are already custom nodes out there). I'd like to experiment with things like looping and incrementing values (like a for loop) for a Ksampler for example. It's only an example though, so I am not looking for a ksampler specific solution; just a generic way to have a variable (e.g. Seed value), run some nodes that use that value,...

I've been playing around with Node-RED[1] for a while and thought I would recreate this using Node-RED (also being a big fan of Node-RED). The flow[2], i.e. code, is online to have a look at (editable but not deployable) and the feed[3] is cached and updated every hour or so. It's only a small Heroku server so it might well be down or about to crash, I make no promises! Thanks to the OP for the inspiration, I did... - Source: Hacker News / about 2 years ago

Node-RED has garnered significant attention and generally positive public opinion for its role in the realms of DevOps, automation, and Internet of Things (IoT). Launched by IBM, this open-source tool offers a flow-based programming model that simplifies the integration of hardware devices, APIs, and online services. It is particularly celebrated for its visual flow editor, which enables users—even those with less programming expertise—to construct complex workflows with ease.
Strengths and Features:
One of Node-RED's key advantages is its low-code platform, which facilitates the development of event-driven applications. By providing a visual interface for connecting various components, it significantly lowers the barrier to entry for building integrations. Users often express appreciation for the intuitive nature of the tool, especially in IoT and automation projects. The ability to create, save, and share JavaScript functions graphically stands out as a favorite feature.
Moreover, Node-RED's open-source nature has bolstered a vibrant community, which plays a crucial role in its continued development and support. The community's active involvement, including the acceptance of external pull requests on platforms like GitHub, ensures that Node-RED remains relevant and up-to-date with user needs. This collaborative spirit is underscored by frequent updates and new features, such as the recent requirement for Node 18.x, which reflect the project's commitment to integrating the latest technological advancements.
Applications and Industry Use:
Node-RED finds extensive application in home automation, as cited in numerous personal projects involving Raspberry Pi, ESP8266, and Arduino. The tool's flexibility and efficacy in managing MQTT protocols and other IoT standards make it highly suitable for dynamic device configuration and environmental monitoring tasks. Its use in industry settings, for instance, by PLC manufacturers like Siemens, attests to its robustness and reliability in real-world applications.
The tool has proven invaluable in scenarios demanding rapid prototyping and deployment of automated workflows, which is why many enthusiasts recommend it for projects requiring seamless integration of disparate technologies. Reports of using Node-RED in conjunction with other software like InfluxDB, Grafana, and AWS further demonstrate its adaptability and effectiveness in diverse ecosystems.
Challenges and Competition:
Despite the positive sentiment, Node-RED faces stiff competition from other workflow automation and integration platforms such as n8n.io, Zapier, and Microsoft Power Automate. While some users believe n8n.io offers a more straightforward, off-the-shelf experience, Node-RED's flexibility and powerful community support often outweigh such alternatives.
Conclusion:
Overall, Node-RED receives strong support and satisfaction from its user base, primarily due to its ease of use, extensive community backing, and suitability for both personal and professional projects. Its role as a versatile tool for wiring together varied technologies ensures its continued relevance in the fast-evolving tech landscape. As with any tool, potential users should weigh its characteristics against their specific needs and the features offered by competitive solutions.
