Managing Director at ITdirector.ie
Flexible and granular security options, good filtering, and the pricing model is cost-effective
The vendor does a really poor job of marketing this software because it should be more popular. This is something that I have pointed out to them. It's a super piece of software, but very few people are aware of it. I am an EX-IT director and I've worked in big systems, and I'm amazed this solution isn't more popular. The "native" integration with other products could be improved. The user interface for the systems that you build can use some improvement because as it is now, you may have to use HTML and CSS to make it look more modern or to match a clients existing look. The documentation is amazing, although they don't do videos and their YouTube channel is very poor. They could create some training videos.
Mitchel Mol BGS - PeerSpot reviewer
CTO at Blue Green Solutions
Has improved development quality and speed but has introduced persistent IDE slowdowns
In recent years, the IDE has been more buggy and slower, and although there have been more features added, I would like to see more stability, as some areas that used to work for a fairly long time are now slower in my development, which feels like a step back. I choose a seven mainly due to the issues we've faced with slowdowns and bugs during development, while runtime has been very stable, and the overall output on Mendix platform is still good; there is definitely some room for improvement, and I would probably have given it an eight or even a nine if those issues weren't hurting my developer output for the past few years. Overall, Mendix platform is stable, but the IDE could be better.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The security is the most valuable feature, in particular, the way I can give different access to different areas to different people, so you can really fine-tune access for different users."
"Overall, I am a big fan of Knack."
"It gave the organizations I worked for the ability to create far more complex applications with a smaller team and in a shorter time frame."
"In short, Mendix has improved our ability to delight our customers."
"I have been using this solution for customer authentication, as well as scientific applications, and it has performed brilliantly so far."
"I think that the workflow and automation features are quite good."
"For a legacy application that typically takes a year, we can now complete it in just one or two months."
"The solution is stable."
"Mostly, the students are very excited about the product due to the fact that they can make applications without coding."
"Mendix as a tool is very, very suitable for a single developer, for business users who have very little knowledge of programming language, so a single developer can create a quick app out of Mendix."
 

Cons

"The user interface for the systems that you build can use some improvement because as it is now, you have to do a lot of HTML and CSS to make it look modern."
"It could use a more comprehensive widget creation studio in the IDE."
"Mendix could improve by allowing the customization of different programming languages, such as Python and C++."
"The vendor should focus more on the opinion of the users and make improvements"
"Mendix is not cheap. License fees go sky high when using it as a business to consumer platform."
"Mendix is quite expensive, and its pricing model makes it inaccessible for startups. The app license costs between $13,000 to $14,000, which is prohibitive for startups."
"I would also like to see automatic adjustment to the Java Heap, whenever an application load becomes too much for the application. It could also use hot database replication."
"Reporting isn't Mendix' strong suite."
"I struggle with solutions like Mendix in terms of creating enterprise solutions."
 

Pricing and Cost Advice

"This product has really good value, as it doesn't have a per-user cost, there's a flat fee."
"Mendix is not open source, but its license cost is cheap, particularly when compared to the Appian license. The license model would depend on how many users you have and how many applications you are creating. If you are creating a single app, you just need to have a single app license, so it's free. If you want a multiple app license to cover two thousand or three thousand users, for example, internal users or external users, then you need to pay for the license. There's also a license model for above three thousand or four thousand, or five thousand internal and external users."
"Initially, we started with a year for approximately $25,000, and if we need to expand the number of seats then we will increase it."
"Pricing used to be complex, but Mendix has improved that quite a bit."
"From a commercial point of view, we would like them to change that they currently sell it as a platform, but as a customer you have to decide upfront the usage of the platform. We would like to have Mendix sell it as a pay as you go model: You pay for what you use, and you don't pay for what you don't use."
"Licensing costs are similar to those for all other IT technology, but they vary by region."
"Its cost is higher than competitors. The cost mostly includes licensing. It is charged per user. The cost model could be better. When you have a big company, what does per user mean? If I have a company where I have 40,000 people who will go to access it but only 200 do, how do you license it and who do you pay for? If they hit it once, do you pay for it? The licensing is complex for a big company. It is easy for us to buy all we can eat, get an enterprise license agreement, and call it good."
"Mendix seems a bit expensive. But in terms of wanting to have less developers and higher velocity, the total cost of ownership is fine. It's not cheap, though."
"I would not recommend the solution to small and medium-sized businesses because it’s expensive. It’s great for big organizations. I rate the pricing as a three out of ten."
