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

"OutSystems is a robust and rapid application development platform with a less steep learning curve."
"The solution is all-encompassing and very easy to use with its drag-and-drop feature."
"It is much easier to develop applications with the product’s IDE."
"OutSystems has no issues so far, the drag and drop environment is quite dynamic, and we can create our own UI on top of it."
"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."
"Scalability proved to be an exceptionally beneficial feature."
"It provides for faster development and better software releases."
"The technical support is perfect."
"Xamarin.Forms reduced the effort and time to build and market our solution, market our features, and get our solution into production."
"My favorite feature of Xamarin platform is the Xamarin.Essentials package. I also like the changes seen in Xamarin's upgrade from Xamarin.Forms to .NET MAUI, because in the older Xamarin Platform, Xamarin.Forms gave you multiple libraries of a particular level for a single platform, whereas .NET MAUI comprises a single, organized library that contains everything needed for both Android and iOS."
"It allows us to reuse our knowledge of C# and .NET Framework."
"You can create one solution in C Sharp."
"The most valuable feature of the Xamarin Platform is the deployment."
"The native features and Xamarin Essentials package are highly valuable to us."
"It significantly reduces development and test costs, and ensures that there is synergy between the platforms on product features and user experience."
"This solution is a cross-form technology, meaning that we don't have to create separate code to deploy apps across different platforms."
 

Cons

"The technical features are good, but the actual commercialization is out of reach."
"We had some lagging issues under high data loads, and the solution needed to be customized to improve this."
"It needs improvement in the AI capability."
"OutSystems could improve by being more like GitHub. It would be more helpful for us for division management and version control for our application."
"The tool needs to improve the efficiency of its widgets."
"Its ability to create and run automated tasks could be better."
"It's difficult to do the component version control. I would like them to add more studying materials."
"There is room for improvement in technical support."
"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 file size is a bit big, so you have to make certain layers."
"The debugging functionality could be improved in Xamarin Platform because sometimes it takes very long to move through the stages of setting up the application build to the final deployment on a mobile app that resides in a physical device."
"The solution does not include Hot Reload which is painful because it causes us to wait quite some time for huge builds."
"The application platform could be improved."
"Xamarin Platform is missing the code renderer."
"From time to time, it is a bit harder to code some specific scenarios compared to the native approach."
"The monitoring of the remote devices is not good as it should be extended along. It would be useful if the log is more integrated with the central console. I am not sure it can be accessed but it would be better."
 

Pricing and Cost Advice

"There is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."
"For a single application, it's too expensive."
"It is still very expensive, so small companies can’t generally afford it... Still, the time saving on development and delivery is worth the value."
"OutSystems is an expensive product. My company has to make monthly payments towards the licensing costs attached to the solution."
"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."
"It is very high price."
"It is too expensive for small companies."
"The subscription is billed on a yearly basis."
"Xamarin Platform is a free open-source solution."
"This is a free product, so there is zero investment on licenses and IDE."
"There's no licensing cost for Xamarin."
"My company provided all the licenses that we need to support our use of Xamarin Platform."
"Xamarin Platform is open-source, but there are fees for deployment, the API Store and Play Store, and using third-party libraries."
"Xamarin Platform is open-source, so it is free to use."
"I think the solution is free."
"There is no requirement for a license. It is available for free as an open-source product."
