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."
"There are free online learning and certifications if a user would like to learn more and better understand the solution."
"The solution is stable."
"On a recent project, using Mendix cut development time by about 40-50% compared to traditional coding for a workflow app."
"The user experience is great."
"Mendix provides the ability to create solutions that fill gaps that I would otherwise be unable to address with standard software."
"The features that I have found most valuable with Mendix are its business process management and its minimal low code, both from an interface perspective and from a process perspective."
"The low-code feature has helped my team and made my work easier because there are default templates, so we don't need to create or write code."
"After implementing Mendix, they reduced by 98% the engineers' relocation, as 98% of the cases are now being done by video calls instead of in-person appointments, which says a lot, even though the company didn't provide any numbers on how much is saved."
 

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."
"One area for improvement is its integration capabilities. Creating a pluggable widget or integrating it with other systems is challenging. In terms of features, it would be great to see advancements such as AI services and the integration of third-party services. Additionally, connecting external devices to the application requires multiple steps. Improving this will make it easier for the developers."
"Needs multiple database connections so an app can directly read/write data to/from multiple databases. This would enable easy splitting of big applications that have complex entity relationships."
"It would also be a 10 if we have a faster Studio Pro, like not taking too much time to process things, especially when projects are too large; those two aspects would make it a 10 for me."
"Mendix could improve by allowing the customization of different programming languages, such as Python and C++."
"What is lacking is the support of higher level modeling features, like the modeling you do is relatively low level, yet it is still close to programming. We would like to see a more business-oriented modeling environment, like BPMN."
"There needs to be an increase in the number of the UI components."
"There should be more integration with engineering applications and tighter integration for user authentication, such as single sign-on, etc. They have some of that. It just could be stronger."
"A constraint of Mendix is that you have to look for the required plugins which takes up development time. There are a limited number of Mendix experts in the market."
 

Pricing and Cost Advice

"This product has really good value, as it doesn't have a per-user cost, there's a flat fee."
"There is a license required to use Mendix. The solution's price is high, but it is best suited for enterprise companies that have the budget. It is not for small or medium-sized businesses."
"Licensing costs are similar to those for all other IT technology, but they vary by region."
"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."
"The solution is a bit expensive compared to others"
"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."
"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 licensing cost is based on the number of apps you have on the server. At the basic level, it is free of charge, so that seems reasonable, but once you go beyond that, and when it comes to the number of users on the app, that basic structure doesn't work, and the pricing tends to get a little bit steep."
"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."

What is your experience regarding pricing and costs for Mendix?
I do not have much experience with the pricing, setup cost, and licensing because the sales or business team usually handles that, and as a developer, I don't have a clear idea.
What needs improvement with Mendix?
I think Mendix can be improved by supporting automated tests more easily. For example, Mendix can add some IDs for each component to build the automation tests more easily.
What is your primary use case for Mendix?
I use Mendix to build a system about the consultation of APIs. We are using Mendix to build a system to check SAP, which is another system, and we use APIs to bring information from SAP to this pro...
