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.

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."
"On a recent project, using Mendix cut development time by about 40-50% compared to traditional coding for a workflow app."
"The development environment is model-driven. We can use the information from this for our business engineers to make the information models, and they can also execute the model."
"I think that the workflow and automation features are quite good."
"I find the fast development speed and low cost to be very valuable features of Mendix. It's a smart solution for busy developers when we need to apply new changes or fixes quickly. Mendix helps to save time and meet project deadlines faster."
"It's amazing that you can build web apps and mobile (hybrid) apps with one code base in a few clicks. It's a full continuous integration environment."
"They are leading in the smart manufacturing, and connectivity space."
"What I like best about Mendix is that it's leading the way for low-code, no-code platforms compared to other solutions in the market."
"The user experience is great."
 

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."
"Mendix needs to think about itself offering machine learning and artificial intelligence."
"Mendix is great for internal applications but not so great for a public-facing interface. It lacks a proper directory structure for public use. The URL will not change from page to page unless a deep link is created for each page. That makes it difficult to bookmark pages in the browser to view later on."
"I struggle with solutions like Mendix in terms of creating enterprise solutions."
"Customization is limited compared to traditional coding, and UI adjustments can feel restrictive."
"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."
"An improvement I would like to see is the ability to version manage independent modules. Their version management for software repositories must be better. It's good and you can do it, but it needs work."
"While the community is great, they need to work on making their direct technical support services better."
"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."
 

Pricing and Cost Advice

"This product has really good value, as it doesn't have a per-user cost, there's a flat fee."
"The solution is a bit expensive compared to others"
"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."
"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."
"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."
"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."
"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."
"Licensing costs are similar to those for all other IT technology, but they vary by region."
"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."

We also use Mendix Enterprise Integration for complex business logic. It's a low-code platform, so we run Mendix in the Mendix Cloud.
What is your experience regarding pricing and costs for Mendix?
I have some idea about the licensing part, and it depends on the person and the number of applications.
What needs improvement with Mendix?
Currently, I do not see any improvements needed in Mendix. However, I have not used Mendix for the last few months, so I lack insight into any new features that might have been added.
