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."
"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."
"You can scale the solution."
"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."
"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 solution is stable."
"The integrated security saves a lot of time, especially when it comes to setting up user-roles and security. Also, database updates work automatically. There is no need to write queries to update the database, once you make an update."
"I highly regard Mendix because of its proper support, troubleshooting options, extensive learning path, and the availability of different types of exams."
 

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."
"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."
"We are all moving away from a monolithic product model to microservices. We are building an F2DUI application to decouple the front and back end. Mendix provides an integrated approach for both."
"While the documentation is good, the development box could be better."
"Overall, integration with the enterprise ecosystem needs improvement."
"In the beginning, it is difficult to learn and work with."
"My understanding is that, if you are not using the free version, it is very expensive."
"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."
"I struggle with solutions like Mendix in terms of creating enterprise solutions."
 

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 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."
"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."
"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."
"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."

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.
