OutSystems facilitates rapid application development and effective project management
What I find valuable about OutSystems is that it has a very good learning curve for developers. Within two weeks, we can gain knowledge in OutSystems, and it is very easy to learn. With my background being .NET, OutSystems is straightforward to learn, which is beneficial. Developing applications in OutSystems is good, and the flexibility allowed by OutSystems for application development is excellent compared to my experiences with other low-code technologies, where I've faced some challenges. The clean separation of concerns in the architecture provided by OutSystems is a key benefit compared to other platforms. OutSystems integrates with our existing tech infrastructure and provides flexible integration. If we want to integrate with third-party services, OutSystems has SOAP and RESTful services that allow us to consume external services, integrate with external databases such as SQL or Oracle, and includes integration studio for writing custom .NET code. After developing a .NET component, we can reference it in service studio, creating a reference file that makes integration easy. OutSystems officially supports various integrations and also includes an API discovery tool for consuming and exposing services, providing a lot of information about incoming URLs, similar to how we use Postman.

Facilitates UI development with XAML, enabling shared UI code across platforms and reducing platform-specific work
I like its simplicity. As someone who didn't start my career as a dedicated developer, I was used to building websites or Windows applications. Transitioning to mobile app development meant learning new languages like Swift or Java. With C# and Xamarin, though, I could leverage my existing skillset. Xamarin, and specifically Xamarin.Forms, let me write my code once and deploy it natively to both Android and iOS. Xamarin.Forms are very useful. Essentially, it's a framework that allows me to create the UI mostly in XAML. This XAML code is then translated into the native UI elements for each respective platform. The advantage is that roughly 90% of my UI code can be shared. This significantly reduces the amount of platform-specific UI work compared to having to write separate UIs for each platform. For the most part, Xamarin's integration with Visual Studio improved the workflow, whether I'm on Windows or Mac. Since I'm familiar with Visual Studio, it provides a comfortable development environment. Additionally, features like Hot Reload and the integration of tools like Copilot help streamline the development process. Overall, it offers a positive development experience.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The flow editor is the most valuable feature. It is simple and intuitive, and it can guide you step-by-step."
"We used almost all of the features, themes, styling guide, and approach components. They are useful in our applications."
"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."
"The most important features of this tool are its visual modeling capabilities and drag and drop functionality. You can see what you are coding which makes it easy to understand and maintain. They have also created a big revolution in digital transformation by introducing native mobile app development under the same IDE."
"OutSystems' low-cost approach has positively impacted our productivity, because we were able to develop faster with OutSystems, enabling us to implement many changes during our sprint."
"OutSystems is easy to use."
"Refactoring with TrueChange is very simple."
"It provides for faster development and better software releases."
"The most valuable feature of the Xamarin Platform is the deployment."
"It has significantly reduced the skill barrier for development and testers."
"The platform is easy to learn as many tutorials are available on YouTube."
"We very much like the XAML design techniques, multiple layout and pages, MVVMCross support, and portability across different platforms."
"The initial setup is very simple."
"This solution is a cross-form technology, meaning that we don't have to create separate code to deploy apps across different platforms."
"The most valuable feature of the Xamarin Platform is that both the UI are the same in Android and iOS, in one project and Android and iOS, are applications for developing PCL projects. Additionally, the dashboard is good."
"The technical support is very good and it's close to native."
 

Cons

"We had some lagging issues under high data loads, and the solution needed to be customized to improve this."
"There are many tutorials available but they are very basic and good for learning the platform. To develop an enterprise-grade application, advanced tutorials need to be developed to help IT professionals design/develop high-quality/performance applications."
"It is hard to find the logic in OutSystems. From an improvement perspective, I want to be able to properly use logic in OutSystems."
"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."
"The dashboards in OutSystems could improve. There are a lot of tabs in the service center that can be confusing."
"We have performance issues while fetching bulk data."
"The tutorials for the solution should be updated."
"While I can't speak to the market impact, as a developer, I've seen significant reductions in development time across different versions of our applications. One area for improvement would be the UI controls in Service Studio. Sometimes, controls don't appear in the IDE, requiring us to check them in the web browser instead. Overall, our experience with OutSystems has been positive, though improvements in UI development would be welcomed."
"The android application compilation time needs to be reduced."
"We need to think about partnering with IBM because there is a need for a big data partner; someone who has machine learning and can help us connect the app to big data."
"From time to time, it is a bit harder to code some specific scenarios compared to the native approach."
"There are compatibility issues between versions of various Xamarin components."
"Xamarin's profiling tools are only available for the highest tier of MSDN subscription and compatibility with platform-native profiling tools is rather lacking. This causes friction when working on performance-related issues."
"It would be better if they offered more certifications. They offer a number of certifications for Azure but none for Xamarin. This is something that could be provided for developers to show off their competency. Technical support could be better."
"The application platform could be improved."
"For those who use only XAML to design the UI, it would be better if there was a better XAML previewer or designer."
 

Pricing and Cost Advice

"OutSystems is expensive, and they changed the pricing model in the last couple of years. It's changing too much and it's becoming unstable. They are constantly shifting their prices based on users, courses, and other factors."
"There is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"It is too expensive for small companies."
"Pricing could be a concern. You have to pay yearly, even after you have completed your development."
"I believe they have two pricing options. One is approximately $4000 USD a year and the other is approximately $10,000 USD a year."
"OutSystems is an expensive product. My company has to make monthly payments towards the licensing costs attached to the solution."
"The tool’s licensing is based on the user’s usage."
"You can build in Xamarin without paying any money."
"There is no requirement for a license. It is available for free as an open-source product."
"I think the solution is free."
"There is no license fee because the solution is open-source."
"Xamarin is available under several licensing arrangements. Each developer needs one license at least. All features, especially the Profiler, unlock only with the highest tier."
"Xamarin Platform is open-source, so it is free to use."
"Xamarin is free. There is no license unless you go for some high-end enterprise features. Other than that, everything's free."
"Xamarin is free, or comes with Visual Studio. Therefore, it is very profitable."
