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."
"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."
"You can scale the solution."
"Mendix has made a great deal of effort to provide its developers a healthy, modern environment for developing. First of all, it adopts Agile methodology by creating a SCRUM-based app where you can handle your user stories. Next comes version control, which really allows multiple team members to collaborate quite easily. And last but not least, Mendix modeler, which is your IDE for developing Mendix apps."
"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."
"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."
"The solution is stable."
"Mendix code and coding logic are very visual. It looks like a flow chart rather than lines of code. Rapid development is what drew us to Mendix."
"It is low code, where the developers can still develop in Java. That to us is very appealing."
 

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 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."
"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."
"We'd like to be able to write in C Sharp to develop code for Mendix."
"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."
"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."
"Mendix is slightly less scalable than I'd like."
"The vendor should focus more on the opinion of the users and make improvements"
 

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"
"Licensing costs are similar to those for all other IT technology, but they vary by region."
"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."
"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."
"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."
"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."
"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."

What do you like most about Mendix?
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.
