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.
Mitchel Mol BGS - PeerSpot reviewer
CTO at Blue Green Solutions
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."
"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."
"We also use Mendix Enterprise Integration for complex business logic. It's a low-code platform, so we run Mendix in the Mendix Cloud."
"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 most valuable features of Mendix are the drag and drop functions, the data entities, domain models, and all the related features."
"The initial setup is easy."
"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."
"Mendix provides the ability to create solutions that fill gaps that I would otherwise be unable to address with standard software."
"Excellent support is offered for Mendix"
 

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."
"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."
"In the beginning, it is difficult to learn and work with."
"Mendix is slightly less scalable than I'd like."
"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."
"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."
"Since it's low-code, I would like Mendix to be web-based, so we shouldn't need to install Mendix to create an app."
"The platform still has many areas for improvement. If I compare apples to apples, the PWA features of Mendix could be improved, for example, I wouldn't recommend creating a B2C or B2B marketplace or web portals on Mendix, but there's a tendency for people to still do it through the systems provided by my company, particularly implement B2B or B2C marketplace, versus using eBay or Shopify. On the web portal front, Mendix still needs to improve."
"Integration with external databases can be slow, and it burdens queries when trying to pull large datasets, thus slowing down page execution."
 

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"
"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."
"Licensing costs are similar to those for all other IT technology, but they vary by region."
"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."
"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."
"Pricing used to be complex, but Mendix has improved that quite a bit."
