Mendix and OutSystems are prominent low-code development platforms that simplify application building through visual interfaces and minimal coding. Mendix emphasizes ease of use, rich visual customization, and a cloud-native architecture that supports diverse deployment scenarios. OutSystems, on the other hand, focuses on enhancing developer productivity and offers robust features for enterprise deployment, including cloud and on-premise options.
The summary above is based on 45 interviews we conducted recently with Mendix and OutSystems users. To access the review's full transcripts, download our report.
"We find it intuitive and easy to use."
"I find the fast development speed and low cost to be very valuable features of Mendix. It's a smart solution for busy developers when we need to apply new changes or fixes quickly. Mendix helps to save time and meet project deadlines faster."
"They are leading in the smart manufacturing, and connectivity space."
"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."
"You can scale the solution."
"It is a brilliant solution."
"What I found most valuable in Mendix is that it's very much suitable for mobile apps such as native Android or IOS supported mobile apps. The multiple features of the platform are very, very attractive and very popular. Mendix has technical features such as microflows and nanoflows. You can also access data models in the platform. These are the features that are very, very strong in Mendix. I got my hands dirty on other low-code platforms, but I have not seen such strong features in them compared to the microflows, nanoflows, and data model access that are in Mendix, including creating and integration. The platform has out-of-the-box adapters or out-of-the-box-connectors that you can integrate with different interface applications such as SAP, Salesforce, Oracle EBS, etc."
"We also use Mendix Enterprise Integration for complex business logic. It's a low-code platform, so we run Mendix in the Mendix Cloud."
"Their out-of-the-box UI is quite good."
"One thing I like about OutSystems is that there's no lock-in. You can keep running your applications because it's on .NET and hosted centrally. That's one of the advantages I see there in terms of not having an IT strategy that has a dependency on a particular platform."
"It is very stable."
"For me, the most valuable feature is the flexibility the tools give us to change any customer requirements on the fly, when we are in a meeting. I also like how easy it is to deploy the code between environments and how easy it is to integrate OutSystems with other systems."
"The technical support is perfect."
"OutSystems is a low-code solution. Most features are like drag-and-drop, so it's pretty easy to work. Thus it helps the organization by saving time for developers."
"We have no complaints surrounding both the scalability and stability of this solution."
"It is a stable solution."
"The code refactoring tools could be better, especially for applications running for years. It's not bad, but it could be smoother. Also, writing new widgets can be trickier than it should be for some people, but not if you're familiar with 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 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."
"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."
"We'd like to be able to write in C Sharp to develop code for Mendix."
"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."
"It could use a more comprehensive widget creation studio in the IDE."
"What is lacking is the support of higher level modeling features, like the modeling you do is relatively low level, yet it is still close to programming. We would like to see a more business-oriented modeling environment, like BPMN."
"The documentation needs to be more robust."
"The new version could be improved."
"Since we first started using OutSystems, they switched their language support from Java and .NET to .NET only, which was a bit of a surprise. Their language support could be better in this sense, although on our resource side it is now a bit more flexible."
"I like the OutSystems platform. I am working on integrating it with another platform using APIs, however, it has proven to be difficult. The main issue I am facing is obtaining authorization tokens as well as access and refresh tokens. It may be due to my lack of knowledge of APIs as it is new to me."
"Currently, in mobile applications, we don't have push notifications."
"The solution's testing framework needs to be improved, and the workflow should be slightly more mature."
"One of the biggest areas for improvement is that every time an existing data element is modified, it creates a new data element. It doesn't really modify that particular data element. So, a user has to follow an extra step of removing the existing data element and bringing in the new and modified data element that is being added, which sort of goes into negative productivity."
"The tutorials for the solution should be updated."
