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

"There is literally a ton of stuff it can do. It's very flexible."
"The solution is all-encompassing and very easy to use with its drag-and-drop feature."
"The integration capabilities have benefited my customers by providing many connectors out of the box, allowing for the integration of external applications or business applications."
"The most valuable feature of OutSystems with discipline and the development processes. Instead of each developer doing tasks on their own with their own approach, et cetera, the solution would help bring some organization to the development process."
"The OutSystems' most effective features for speeding up development cycles are the process orchestration and the drag-and-drop updating of business processes."
"The most valuable feature is Agile development. I love that you save a lot of time on development and can focus on logic and business requirements."
"It provides for faster development and better software releases."
"It is a scalable solution...The initial setup of OutSystems is easy."
"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."
"It usually saves time for application development. We write once and the code works everywhere."
"The most valuable features of the Xamarin Platform are that it has cross-platform development, one code base serves a purpose on both, and the grid layout is a lifesaver."
"Xamarin Platform's best features are its single codebase, the support from Microsoft, and the free libraries."
"The best part while using the Xamarin Platform is a cross-platform application. We could execute iOS and Android while writing a single line of code."
"This solution is a cross-form technology, meaning that we don't have to create separate code to deploy apps across different platforms."
"Being able to use the .NET framework and platform have me creating applications better than anyone who develops on Windows."
"Cross-platform development saves time and provides consistencies."
 

Cons

"The largest obstacle currently associated with OutSystems is its high cost and limited availability of skilled personnel. Despite being a rapid application development platform, having a highly skilled individual familiar with the platform can be much more beneficial than an inexperienced individual. Because there is a shortage of people with the necessary OutSystems skills, utilizing the platform can become expensive. This makes little sense, considering that a rapid application development platform should be accessible to the average person. However, having a highly skilled individual can greatly increase productivity, making the cost worthwhile."
"OutSystems does not provide any native reporting resources. All reports must be created with other tools or as a webpage."
"The cons involve delays in project timelines primarily due to the time taken in requirements refinement and challenges faced when adding new features, making it somewhat complex to manage and maintain applications as they grow in scale."
"The installation is a bit tedious."
"The product's high price is an area of concern, where improvements are required."
"Currently, in mobile applications, we don't have push notifications."
"It needs improvement in the AI capability."
"The customer service and support are maintaining a two-day SLA for everything. 48 hours is very high."
"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."
"The recent move to .NET MAUI is a big change that's affecting a lot of the good features."
"The file size is a bit big, so you have to make certain layers."
"It needs offline sync capabilities to store data on devices persistently."
"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."
"Xamarin Platform can improve if there was a virtual test environment so we did not have to have a Mac system for the iOS testing. At this time You must have a Mac to deploy or generate IBA profiles."
"We have noticed that there have been stability-based performance issues with this product, which need to be improved."
"There are compatibility issues between versions of various Xamarin components."
 

Pricing and Cost Advice

"I would rate it five to six out of ten."
"OutSystems was open to a deal that worked for both sides."
"Pricing could be a concern. You have to pay yearly, even after you have completed your development."
"The product is expensive and I would rate its pricing a seven out of ten. You need to pay a yearly subscription to use the product."
"The tool’s licensing is based on the user’s usage."
"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 a very expensive solution, and it has to be cheaper."
"For a single application, it's too expensive."
"This is a free product, so there is zero investment on licenses and IDE."
"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 is free, or comes with Visual Studio. Therefore, it is very profitable."
"Xamarin Platform is open-source, so it is free to use."
"It saved a lot of time and resources needed to develop a cross platform mobile app."
"There's no licensing cost for Xamarin."
"Xamarin Platform is open-source, but there are fees for deployment, the API Store and Play Store, and using third-party libraries."
"Xamarin is free. There is no license unless you go for some high-end enterprise features. Other than that, everything's free."
