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

"Overall, I am a big fan of Knack."
"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 is stable."
"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."
"Mendix is an excellent tool to put the business in charge again for realizing IT projects."
"The initial setup is easy."
"On a recent project, using Mendix cut development time by about 40-50% compared to traditional coding for a workflow app."
"Most valuable is the fact that the Mendix platform provides all the tools for creating and deploying business applications in one complete package."
"There is a free version of the solution you can use."
"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."
 

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 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."
"I struggle with solutions like Mendix in terms of creating enterprise solutions."
"A constraint of Mendix is that you have to look for the required plugins which takes up development time."
"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."
"An improvement I would like to see is the ability to version manage independent modules. Their version management for software repositories must be better. It's good and you can do it, but it needs work."
"From Mendix 6 until 7, options on creating mobile apps have improved, but offline capabilities are not mature enough."
"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."
"We'd like to be able to write in C Sharp to develop code for Mendix."
"It could use a more comprehensive widget creation studio in the IDE."
 

Pricing and Cost Advice

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

What is your experience regarding pricing and costs for Mendix?
I do not have much experience with the pricing, setup cost, and licensing because the sales or business team usually handles that, and as a developer, I don't have a clear idea.
What needs improvement with Mendix?
I think Mendix can be improved by supporting automated tests more easily. For example, Mendix can add some IDs for each component to build the automation tests more easily.
What is your primary use case for Mendix?
I use Mendix to build a system about the consultation of APIs. We are using Mendix to build a system to check SAP, which is another system, and we use APIs to bring information from SAP to this pro...
