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.

Cloud-based, helps fill gaps and that seamlessly integrates with existing systems
Mendix provides the ability to create solutions that fill gaps that I would otherwise be unable to address with standard software. It integrates seamlessly with my existing ERP systems, enabling me to build attractive and user-specific solutions. Its cloud-based platform supports agile methods and enhances my development speed. These features enable me to better meet my organizational needs.

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."
"Excellent support is offered for Mendix"
"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."
"I think that the workflow and automation features are quite good."
"The solution is stable."
"The domain model of Mendix is highly valuable as it allows quick setup and public deployment."
"You can scale the solution."
"Enables us to rapidly create a complex application. We are also able to customize features that stakeholders in the corporation want to see, something that could not be done with other software. Our workflows and processes have evolved and improved. The fast iterations allow us to be nimble, get feedback from users, and do rapid updates."
"It is a development platform which assists in accelerating your developmental lifecycle. This is one of its most valuable features. This solution also offers a good set of components that are readily available."
 

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 needs to provide an overview of model versioning control for the sake of the review process; better SCRUM board; an overview of model changes from the repository through Sprintr (SCRUM board). Also, a choice between versioning control system would be nice."
"There's no direct tech support."
"There needs to be an increase in the number of the UI components."
"We'd like to be able to write in C Sharp to develop code for Mendix."
"While the community is great, they need to work on making their direct technical support services better."
"It could use a more comprehensive widget creation studio in the IDE."
"I would like to see more documentation as well as how-to documents."
"In the beginning, it is difficult to learn and work with."
 

Pricing and Cost Advice

"This product has really good value, as it doesn't have a per-user cost, there's a flat fee."
"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 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."
"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."
"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."
"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."
"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."
"Pricing used to be complex, but Mendix has improved that quite a bit."

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.
