Managing Director at ITdirector.ie
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."
"Overall, I am a big fan of Knack."
"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."
"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."
"The initial setup is easy."
"The software is mainly designed and built by business engineers instead of software engineers, which leads to an immediate fit between delivered software and what the users really want."
"Its graphic interface, which allows you to develop rapidly and in a structured way, and the fact that it is an all-in-one solution, producing a system that is ready to run immediately."
"Mendix is an excellent tool to put the business in charge again for realizing IT projects."
"The ability to deploy functionality daily, weekly, or monthly has greatly increased our competitive advantage in the market."
"I enjoy the low-code nature of the product; it's user-friendly, very easy to handle, and the product was easy to set up."
 

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."
"Mendix could improve in customization and UI, UX flexibility, native mobile development, and agile tooling for developers."
"Lastly, the licensing model does not scale well with many users. This is a huge problem as apps that have many users become very expensive and can kill the business case."
"For small companies the pricing can be a bit steep."
"The cost model could be better. It is expensive."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"This product has really good value, as it doesn't have a per-user cost, there's a flat fee."
"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."
"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."
"Pricing used to be complex, but Mendix has improved that quite a bit."
"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."
"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."
"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."
