Rapid delivery has transformed complex enterprise apps and supports faster cross-domain projects
Every platform or low-code platform tool is quite good in its own area, but there is always space to groom or enhance or improve. The same is with OutSystems as well. A couple of things from the integration point of view can be enhanced. If your application or the enterprise organization is tackling a huge data application where you have bulk amounts of data, it becomes a challenge for all the technologies and the same with OutSystems. You have to design your architecture in a very magnificent and decent way so that how you process your data so that load can be easily balanced. Data handling and huge data handling is a kind of challenge you may need to face. Then we have some vendor lock-in. If you are trying to migrate your application from OutSystems, then you probably get into this vendor lock-in system. Some organization may face challenges if some organization is on a small scale size. The small scale businesses may find OutSystems costly because of its high cost and pricing due to the licensing cost. Apart from that, OutSystems really plays well, and it needs a learning curve. If a traditional application or programming is there which your developers are skilled into and they are directly deployed into OutSystems, it may take some significant amount of time for them to get comfortable with OutSystems. There is a learning curve. OutSystems community is already in place, but it can more be enhanced regarding some aspects. They did organize lots of bootcamps and other user groups as well, but those can also be improved from the documentation point of view and having some integration guidebook as well. A couple of things which can be improved into OutSystems include the licensing cost, the vendor lock-in side, the learning curve, couple of integration aspects and customizations.

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 really good platform to work upon."
"It is very stable."
"The OutSystems' most effective features for speeding up development cycles are the process orchestration and the drag-and-drop updating of business processes."
"We've used features like batch processing timers, components, and integrations with other systems like SAP, which have accelerated our development process.In terms of productivity, we've seen a 30 percent reduction in screen design time and an additional 10 percent improvement when implementing client requirements. OutSystems' integration capabilities have significantly enhanced our app's functionality, making it quicker and easier to connect with other systems."
"The flow editor is the most valuable feature. It is simple and intuitive, and it can guide you step-by-step."
"One of the valuable features of OutSystems is the very small lead time for the delivery of projects."
"Integrations with external systems with SOAP and REST are easy to implement off-the-shelf, but a developer can always implement specific libraries for other integrations."
"It is much easier to develop applications with the product’s IDE."
"The cross platform ability is a great asset."
"Their leadership is exceptional at both listening to the customer base and delivering innovative, best-in-class products."
"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."
"The technical support is very good and it's close to native."
"The initial setup is very simple."
"The native features and Xamarin Essentials package are highly valuable to us."
"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."
"It significantly reduces development and test costs, and ensures that there is synergy between the platforms on product features and user experience."
 

Cons

"The product could benefit from improved connectors to integrate with outside platforms."
"I would like to see more integration between the use of artificial intelligence to speed up the process delivery time."
"The initial setup of OutSystems is not easy. It is a very heavy application that requires a lot of hardware and software resources."
"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 small-scale businesses may find OutSystems costly because of its high cost and pricing due to the licensing cost."
"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."
"There are not enough resources on the market."
"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."
"I feel that the Android AppCompat library creates a lot of issues. A lot of development time is often wasted solving these issues."
"There is room for increasing the scale a little bit further with the designer in the Visual Studio, more specifically, Xamarin.Android Designer in Visual Studio."
"They need to improve performance, especially for the Android platform. Also, some controls are missing in the Xamarin framework when compared to native controls; for example, the checkbox control."
"The file size is a bit big, so you have to make certain layers."
"Xamarin Platform's performance base could be improved."
"The architecture in the Xamarin Platform has to improve, there are some features missing."
"There are compatibility issues between versions of various Xamarin components."
"For beginners, the entire setup can be overwhelming because it involves setting up development environments for iOS, Android, and Windows at the same time if you want to target all three."
 

Pricing and Cost Advice

"It's not cheap. It's pretty expensive."
"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."
"For a single application, it's too expensive."
"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
"Pricing could be a concern. You have to pay yearly, even after you have completed your development."
"OutSystems was open to a deal that worked for both sides."
"It is very high price."
"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."
"Xamarin is free, or comes with Visual Studio. Therefore, it is very profitable."
"I think the solution is free."
"There is no license fee because the solution is open-source."
"The product is inexpensive."
"There's no licensing cost for Xamarin."
"It saved a lot of time and resources needed to develop a cross platform mobile app."
"Xamarin Platform is a free open-source solution."
"In most cases, it is sufficient to have free/community license. But if you plan to seriously develop production-level, highly polished apps, you need to use Xamarin.Profiler and the professional or enterprise license."
