I am advocating the use of this solution in my organization. I use it personally for my purposes and for the company, I use it for internal data science with very good results.
Test Engineer at ProData Consult
An impressive open-source product that is stable and easy to use
Pros and Cons
- "What I like the most is that it works almost out of the box with Random Forest and other Forest nodes."
- "The documentation is lacking and it could be better."
What is our primary use case?
What is most valuable?
What I like the most is that it works almost out of the box with Random Forest and other Forest nodes.
What needs improvement?
It is difficult to say at this time, as I am not using the latest version. I have noticed that I don't have the latest modules that were added, such as ML.
In my opinion, there's one thing lacking. As far as algorithm notes go, it would be handy if category algorithms of C4 or C4.5 could be set with a checkbox or something like that.
Once you go to the forum or the documentation, to see how to implement a C4.5, you mark the checkbox, and only then it would be content for C4 or C4.5.
The documentation is lacking and it could be better. It's a community-driven product but there are a few crucial models missing such as ANOVA and MANOVA.
For how long have I used the solution?
I have been using KNIME since December 2019.

What is most valuable?
It can handle an unlimited amount of data, which is the advantage of using Knime.
It already has algorithms included.
What needs improvement?
I haven't had a lot of time to explore Knime in detail, but when you compare it with Orange, I would like it to be able to find data and collect it from another source. Also, to collect data for Knime from Twitter, Instagram, or Facebook for example, and to add widgets to Knime.
It could input more data acquisitions from other sources and it is difficult to combine with Python. It can be done with special requirements.

BI Solutions Developer at a tech services company with 201-500 employees
Open source with good analytic capabilities and very stable
Pros and Cons
- "The product is open-source and therefore free to use."
- "They should look at other vendors like Alteryx that are more user friendly and modern."
What is most valuable?
The data analytics capabilities in KNIME are excellent. It's not just a statistical ETL tool. We can go deeper and do various types of tasks beyond straight analytics.
The product is open-source and therefore free to use.
The solution offers lots of different options.
What needs improvement?
The user interface could be a bit better. It's currently very dated.
They should look at other vendors like Alteryx that are more user friendly and modern.
From a systems point of view, the tool is not completely user friendly.
Users tell us they would like to do their own analytics and find it difficult to accomplish without the help of a technical service.
You need to be a bit more knowledgeable in order to handle the solution. It's not difficult, it's just more technical than other options.
For how long have I used the solution?
I've been dealing with the solution for four years.
What do I think about the stability of the solution?
The solution is very stable. There aren't issues surrounding bugs or glitches. It doesn't crash or freeze. It's quite reliable.
What do I think about the scalability of the solution?
It depends on the requirements you have, however it is scalable, at least for the next two years.
We typically work with enterprise-level organizations. The companies aren't that small.
How are customer service and technical support?
The technical support is okay. I'd give them three out of five stars.
I don't find any of their online tutorials help anyone at all. I am comparing KNIME with Alteryx mainly due to the fact that those two are the main ETL tools which most of my clients use. The technical support and documentation that are available for Alteryx are quite good. We don't get that level of documentation or videos from KNIME's support. It's very limited.
Which solution did I use previously and why did I switch?
We also use Alteryx. We use both solutions, depending on the client. I tend to recommend Alteryx. For someone who has good technical knowledge, they can go with KNIME. However, if they're not a techy person, I would recommend Alteryx for them.
How was the initial setup?
The initial setup is not complex. It is pretty easy. However, you have to know what to do. If you have software demo documents or if you have tutorials to support you, then it is easy. I wouldn't say that it's a complex tool at all. It's pretty easy.
What's my experience with pricing, setup cost, and licensing?
The solution is open-source and therefore cheap to use. Anyone can access it. They can just download it off the internet and start. Alteryx is way too expensive. In terms of pricing, it's always better to go with KNIME.
What other advice do I have?
I am both consultant and a vendor right now. We do a bit of consultant work for some of our clients and we give the tutorials to them. We typically get in touch with them, and they send what they need and we do the distribution for them.
I'd recommend new users have their requirements sorted out first so that they know what they need out of the tool. If that is clear, they can install the custom content required in KNIME to get their analytics done correctly. If that is there, then it's a piece of cake.
Overall, I'd rate the solution eight out of ten. If the user interface was better and it offered better technical support, I would rate it higher.

Business Analyst at a retailer with 501-1,000 employees
Allows me to integrate several data sets quickly and easily, to support analytics
Pros and Cons
- "We are able to automate several functions which were done manually. I can integrate several data sets quickly and easily, to support analytics."
- "Valuable features include visual workflow creation, workflow variables (parameterisation), automatic caching of all intermediate data sets in the workflow, scheduling with the server."
- "The overall user experience feels unpolished. In particular: Data field type conversion is a real hassle, and date fields are a hassle; documentation is pretty poor; user community is average at best."
What is our primary use case?
All analytics individuals use KNIME to integrate multiple sources of data (SQL, excel, etc.) and prep the data for static reporting.
How has it helped my organization?
We are able to automate several functions which were done manually. I can integrate several data sets quickly and easily, to support analytics.
What is most valuable?
- Visual workflow creation
- Workflow variables (parameterisation)
- Automatic caching of all intermediate data sets in the workflow
- Scheduling with the server
What needs improvement?
The overall user experience feels unpolished.
- Data field type conversion is a real hassle, and date fields are a hassle.
- Documentation is pretty poor.
- User community is average at best.
For how long have I used the solution?
Less than one year.
What do I think about the stability of the solution?
It is pretty stable.
What do I think about the scalability of the solution?
Partially, only with very large datasets (10M+ records or so); its reliance on RAM is a bit high for normal PCs. Servers should be fine.
How are customer service and technical support?
Not applicable (not local in South Africa).
Which solution did I use previously and why did I switch?
Alteryx. KNIME is much cheaper. The KNIME desktop client is free. KNIME handles 95% of our requirements.
How was the initial setup?
Straightforward.
What's my experience with pricing, setup cost, and licensing?
KNIME desktop is free, which is great for analytics teams. Server is well priced, depending on how much support is required.
Which other solutions did I evaluate?
Alteryx.
What other advice do I have?
I rate it a seven out of 10. It's very useful but needs polish and improved UX and UI in several areas.
For quick adoption, either get KNIME to provide training, or have a local knowledge expert on hand who is well versed with data workflow tools, and databases if necessary.

Business Intelligence Manager at Telecoms
It has allowed us to easily implement advanced analytics into various processes
Pros and Cons
- "It has allowed us to easily implement advanced analytics into various processes."
- "Data visualization needs improvement."
What is our primary use case?
Primarily used for advanced analytics, include designing and running predictive models, and conducting segmentation analysis. With KNIME, I connect to different data sources but usually need to conduct some data transformations before the main task is carried out. My results are usually written to a database, then I use a different tool for data visualization
How has it helped my organization?
It has allowed us to easily implement advanced analytics into various processes.
What is most valuable?
Easy to use nodes for ETL processes. This is because, in many cases, I usually transform the data before the main task even when the data is from a structured database.
What needs improvement?
Data visualization.
For how long have I used the solution?
One to three years.

Solutions Architect at a retailer with 10,001+ employees
Should have better connectivity, although the solution is stable and allows for easy dragging and dropping of basic algorithms
Pros and Cons
- "I was able to apply basic algorithms through just dragging and dropping."
- "I would prefer to have more connectivity."
What is most valuable?
The solution allows one to do many things, including data preparation. I was able to apply basic algorithms through just dragging and dropping. This in contrast to Python and other solutions, which involve much coding.
What needs improvement?
I would prefer to have more connectivity. The user documentation is insufficient. I would like to see more enterprise level application. There are high end features which should appear, the MLOps platform being one. This feature is key.
There should be better connectivity to such platforms as AWS and SageMaker, as we rely heavily on AWS in RL. For certain South Asian markets, we plan to go with Azure, so it is important to have connectivity to both of the major clouds. There should be AI machine learning based algorithms. Such features should be available out of the box with good precision.
For how long have I used the solution?
I have worked with KNIME for a couple of months.
What do I think about the stability of the solution?
The solution is stable.
What's my experience with pricing, setup cost, and licensing?
KNIME assets are stand alone, as the solution is open source. I have not looked into their enterprise level application costs. While cost is a parameter, I would definitely consider other options which provide value for one's money.
What other advice do I have?
The solution is good for small scale implementation. Other solutions should be considered for enterprise level implementation.
I rate KNIME as a five or six out of ten.

Professor at Mines Rabat
A stable teaching tool
Pros and Cons
- "The solution is good for teaching, since there is no need to code."
- "Both RapidMiner and KNIME should be made easier to use in the field of deep learning."
What is most valuable?
The solution is good for teaching, since there is no need to code. When teaching, the work flow, the process, is easy to explain to students. They understand that there are four steps in data mining on the machine learning project. Data must be injected and cleaned, after which engineering features must be made. Finally, the model must be created and deployed. Both KNIME and RapidMiner have these capabilities.
What needs improvement?
An improvement which can universally be made to products is to make them more simple. Code-less products are simplified. Both RapidMiner and KNIME should be made easier to use in the field of deep learning.
While KNIME has all the requisite features, there is a shift from coding to programming with virtual language. It is only a process of making one's solution easier to use.
For how long have I used the solution?
I have been using KNIME for more than 14 years.
What do I think about the stability of the solution?
The solution is good and they have made improvements over the last version. The same holds true for RapidMiner. Both products are very good.
What other advice do I have?
The best way to use the solution is to dive in, get practice and use it more.
I rate KNIME as a nine out of ten.

VP, Software and IT Service at ITZone LLC
Easy to use and reasonably priced, but more training material needs to be made available
Pros and Cons
- "This solution is easy to use and it can be used to create any kind of model."
- "KNIME needs to provide more documentation and training materials, including webinars or online seminars."
What is our primary use case?
We are a solution provider and KNIME is a product that we are working on reselling to our customers. We sell BI tools such as Tableau and many of our customers that are using these tools need to have an AI solution. They have lots of use cases for AI including, for example, those from the financial sector would like to use AI for credit scoring. We also have government clients who will have their own specific use cases.
We have not yet sold it to any of our customers because they are still using the free tools and we are promoting it based on that.
What is most valuable?
The nicest part of KNIME is that the designer tool is free.
This solution is easy to use and it can be used to create any kind of model.
What needs improvement?
We are worried about the performance when it comes to using a lot of data that has many rows and columns. On the server-side, we are not sure whether KNIME can manage or handle large amounts of data without issue. It looks like it will easily work for small datasets but we are concerned about performance as the volume increases.
KNIME needs to provide more documentation and training materials, including webinars or online seminars. At this time, it is not sufficient when compared to some other vendors.
The user interface needs to be improved because it looks quite messy and I am not very comfortable using it.
For how long have I used the solution?
I have been familiar with KNIME for two or three years but we have been actively interested in it for less than a year.
How was the initial setup?
We have not deployed the entire solution for a customer yet. However, we have been working with the design tool, which does not require deployment. You just have to download it and then it can be used for testing demonstration data.
What's my experience with pricing, setup cost, and licensing?
The price of KNIME is quite reasonable and the designer tool can be used free of charge.
What other advice do I have?
Many of our customers have streaming data and want to use an AI model. We do not yet know whether KNIME will handle live-streaming and it is something that we intend to test.
I would rate this solution a seven out of ten.
Disclosure: My company has a business relationship with this vendor other than being a customer: reseller
