Enables users to develop applications quickly and has a responsive and helpful technical support team
The time to market is quite good. We can quickly develop an application using the tool. OutSystems is developed using .NET and Java. We can easily find technical resources who have worked on .NET and Java and leverage their previous knowledge to develop OutSystems applications. It can also be used for application development. If an end-user does not want to use the solution after two to three years, OutSystems sends the source code and the applications to the end-user. There is no dependency. It’s one of the major factors I found quite good in OutSystems.

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 scratch coding is useful. The solution is easy to understand."
"We can quickly develop an application using the tool."
"It is a stable solution, and the initial setup is straightforward."
"OutSystems' best feature is that you can build tests with the flow, so even the tests are made in the PDD framework in a low-code way."
"The most valuable feature of the solution is that it allows users to easily build applications."
"The architecture of OutSystems is quite simple, and the features are similar to Mendix's. OutSystems has connectors for different enterprise apps and solid reporting capabilities. You can also integrate with any content management platform like SharePoint or Adobe Enterprise Manager, or something like that. You can also create and integrate workflows."
"It is a stable solution."
"You can go huge - so it is definitely a scalable solution."
"For me, developing apps for iOS and Android is a dream came true, without migrating to Objective-C or Java. Xamarin enables me to do so."
"Plugins like MvvmCross make a developer’s life 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."
"The cross platform ability is a great asset."
"It is a true native solution, and we can use the cross-platform framework."
"Xamarin Platform enables you to use a single code language. This is beneficial for Android, iOS, and Windows platforms, so they can be developed over application or built over application."
"The platform is easy to learn as many tutorials are available on YouTube."
"The Xamarin platform can reduce overhead significantly through code-share and reuse. The typical team size for a Xamarin project is significantly reduced compared to purely native projects."
 

Cons

"The new version could be improved."
"The integration points need to be increased. People have also started to adopt this solution for their regular needs. That means it's not only the big enterprises that are adopting this solution. There are also small and medium enterprises that are adopting it. I've read that where you have large deployments, OutSystems starts to crumble a bit. That is the idea that no customer would know at the beginning and would also not like to hit the wall there. When it is on the client, there are a lot of applications already on low-code, and then suddenly you realize that you want to do some big applications, and you face hurdles. This is the general feedback for all such platforms."
"In my opinion, the support and the pricing could be better."
"There are not enough resources on the market."
"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."
"I think OutSystems needs to improve in many areas. First, sometimes Service Studio becomes really slow and even hangs for long periods. Also, if I have not published my module in some time, and some kind of Service Studio exception occurs, I lose my work."
"The product could benefit from improved connectors to integrate with outside platforms."
"I would like to see OutSystems improve its integration capabilities, especially with emerging technologies like AI and GPT."
"The solution always has room for improvement with price, integration, stability, and documentation."
"The major I see with Xamarin right now is that there is no visual editor"
"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 problem that I faced was that the communication, the roles, and the responsibilities, weren't defined between Microsoft and Xamarin."
"The application platform could be improved."
"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."
"All Xamarin library issues need to be taken care of as a top priority."
"The performance needs improvement, especially the dev tools, and also the ultimate output of the mobile applications."
 

Pricing and Cost Advice

"It is too expensive for small companies."
"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
"For a single application, it's too expensive."
"The solution is expensive."
"There is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."
"I would rate it five to six out of ten."
"The subscription is billed on a yearly basis."
"There are no additional costs with the standard license."
"Xamarin Platform is open-source, but there are fees for deployment, the API Store and Play Store, and using third-party libraries."
"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 a free open-source solution."
"This is a free product, so there is zero investment on licenses and IDE."
"The price of the Xamarin Platform is not expensive. However, the price of the solution depends on the application that is made. For example, if you have small applications, it's different from large or enterprise applications."
"You can build in Xamarin without paying any money."
"For personal use, the Community Edition is free."
"My company provided all the licenses that we need to support our use of Xamarin Platform."
