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."
"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."
"The most valuable features of the product are its ease of use and speed. My friend and I find it helpful as a team of just two developers."
"Excellent support is offered for Mendix"
"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."
"Suite allows you to easily and smoothly integrate with pretty much anything. It is also cloud-enabled. It provides a full Cloud Foundry-driven cloud environment with one-click deployment."
"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."
"Mendix isn't just an IDE or a coding language; it's a whole platform where you don't have to worry about hosting or monitoring your application, tracking project progress or user stories, as everything is essentially provided by the platform, and it has a very active community helping you out if you have any questions at all."
 

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."
"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."
"One thing I would like to improve is the support system offered by Mendix. It can sometimes take a while to get the help I need when I'm using Mendix."
"I would also like to see automatic adjustment to the Java Heap, whenever an application load becomes too much for the application. It could also use hot database replication."
"Mendix could improve by allowing the customization of different programming languages, such as Python and C++."
"It could use a more comprehensive widget creation studio in the IDE."
"Feature-wise and in terms of technical aspects, Mendix is excellent, but its pricing is steep."
"There are not enough developers who are using Mendix. The knowledge base available online and in the market is not as rich as other competitors."
"While the documentation is good, the development box could be better."
 

Pricing and Cost Advice

"This product has really good value, as it doesn't have a per-user cost, there's a flat fee."
"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."
"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."
"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."
"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."
"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."
"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 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.
