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 is low code, where the developers can still develop in Java. That to us is very appealing."
"We also use Mendix Enterprise Integration for complex business logic. It's a low-code platform, so we run Mendix in the Mendix Cloud."
"The software is mainly designed and built by business engineers instead of software engineers, which leads to an immediate fit between delivered software and what the users really want."
"You could actually build an application as someone from the business side is explaining what the solution requires."
"The solution is stable."
"The pricing is very clear, with no hidden fees."
"For a legacy application that typically takes a year, we can now complete it in just one or two months."
"There is a free version of the solution you can use."
 

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."
"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."
"ROIs at this stage is not good because of the high license fees."
"Mendix could improve by allowing the customization of different programming languages, such as Python and C++."
"There's no direct tech support."
"The code refactoring tools could be better, especially for applications running for years. It's not bad, but it could be smoother. Also, writing new widgets can be trickier than it should be for some people, but not if you're familiar with Mendix."
"I struggle with solutions like Mendix in terms of creating enterprise solutions."
"There is always a layer of custom code required."
"In the next version I would like the Rest Service Module to be incorporated into Mendix, similar to the way web services work."
"The initial setup is more complex. I've also noticed that people that have a first-time interaction with it find it more difficult to grasp."
 

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."
"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."
"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."
"Pricing used to be complex, but Mendix has improved that quite a bit."
"Licensing costs are similar to those for all other IT technology, but they vary by region."
"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."
"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."
"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."

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...
