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

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."

"The best feature is that you can create applications real fast."

"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."

"In our biggest project to date, we replicated with somebody else, it took three years to do uncompleted, and we replicated it in about six months to build an end-to-end application for customer use."

"Micro flows, because of the ease of use for complex development structures Wide variety of in app store Widgets such as Deep Link, Active Directory integration, graphs (bar/spider charts), and geo location functionality Ability to customize the style sheets Mobile development framework Java integration with Mendix Remote debugging The ease of use for complex development structures SAP integration"

"The built-in security makes security-by-design from the start possible."

"Dashboards are valuable; it is easier to visualize data, and it is low code where the developers can still develop in Java, which to us is very appealing."

"Mendix allows for faster development while saving on fewer FTWs (full-time workers), a win-win in most cases."

"We are able to service our customers in a way that differentiates us, making us more competitive and enabling us to expand our business."

More Mendix pros

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."

"My understanding is that, if you are not using the free version, it is very expensive."

"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."

"Generally, the customer support takes around two weeks to respond to support tickets, but everything gets resolved."

"The cost model could be better. It is expensive."

"Improvements for Mendix include that sometimes it gets hung while loading."

"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."

"Mendix could improve in customization and UI, UX flexibility, native mobile development, and agile tooling for developers."

"ROIs at this stage is not good because of the high license fees."

More Mendix cons

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 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."

"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."

"The solution is a bit expensive compared to others"

"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."

"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."
