"A good way to program apps without code"

3/5

What do you like best about Node-RED?

I love to use Node-RED frequently to make POC in a straightforward way because you don't need to code anything, its so easy to implement with other services, the simply graphical drag and drop feature allows to connect blocks of functions without write one line of code, so you can make an entire workflow in few steps and few minutes. Review collected by and hosted on G2.com.

What do you dislike about Node-RED?

The graphical approach will limits the option to add code, in certain blocks you can add javascript scripts but you always became limited by the blocks itself, so you need to be careful to maintain the Node-Red architecture once you try to export the design to its code equivalent. Review collected by and hosted on G2.com.

What problems is Node-RED solving and how is that benefiting you?

I can make an entire solution using preprogrammed blocks, I can modify my workflow only changing the links connections between blocks so it's nice to debug or experiment with many ways to solve your problem focusing on the usage of your application and not in the code. I can recreate a complete API with 3 blocks and 0 lines written, so you can test filters, functions, payloads, so on without the need to have many instances running and paying for each of those.

"Flexibility and adaptability"

4.5/5

What do you like best about Node-RED?

Simple and effective business process software. You can check the process at any time. I can't imagine another system to implement the connection of two systems and exchange of data between them. Node-RED has a great, large and helpful developer environment. You can contact them on the forum and get advice, hints or help. Review collected by and hosted on G2.com.

What do you dislike about Node-RED?

I recently did a B2B system integration with a logistics provider.

I, for one, can't point to things that annoy me. Review collected by and hosted on G2.com.

"Best solution for automation and integrating any devices available"

5/5

What do you like best about Node-RED?

Node-RED is the best solution for automation and integrating any devices available, be it Zigbee, MQTT, Wifi, a wide range of cloud devices and services and a lot of messengers and notification solutions. Review collected by and hosted on G2.com.

What do you dislike about Node-RED?

The library of Node-RED is huge, there is a lot of packages to look at and to try before there is a perfect match. And the memory footprint seems somewhat high. Review collected by and hosted on G2.com.

"Best flow programming environment for IoT"

5/5

What do you like best about Node-RED?

The Node-RED main strength is its simplicity. With a visual paradigm, managing IoT protocols, automation, and technological barriers is a piece of cake for almost everybody. Review collected by and hosted on G2.com.

What do you dislike about Node-RED?

Sometimes the number of nodes tends to be high, increasing the complexity and making interpretation difficult. Luckily, grouping and "sub-flow" mechanisms mitigate this frequent problem. Review collected by and hosted on G2.com.

"A good tool based on nodejs for complex workflows"

4.5/5

What do you like best about Node-RED?

"Easiest automation and IoT development"

5/5

What do you like best about Node-RED?

Node-RED has a list of pre-developed libraries for almost all famous sensors. So, you need not to worry about writing long codes for each and every other sensor on your project. UI will help you to map out whole automation process and sensors. Review collected by and hosted on G2.com.

What do you dislike about Node-RED?

Node-RED comes with a bundle of internal dependent files and information which consume a lot of memory. So, if you're running low on memory then Node-RED isn't a good choice according to me. Review collected by and hosted on G2.com.

"Node-Red and HiveMQ"

5/5

What do you like best about Node-RED?

Node-Red is a really simple to use "language" and HiveMQ simply works (seamlessly) with it Review collected by and hosted on G2.com.

What do you dislike about Node-RED?

Nothing to disike about HiveMQ - with the web front end and ability to access the broker via node-red I have apps up and running within minutes (ok, maybe 30 minutes) Review collected by and hosted on G2.com.
