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

"Let's assume a project in .NET, native .NET, or Java takes around 12 months. In OutSystems, we can build that application in four to five months."
"One of the valuable features of OutSystems is the very small lead time for the delivery of projects."
"The OutSystems' most effective features for speeding up development cycles are the process orchestration and the drag-and-drop updating of business processes."
"Refactoring with TrueChange is very simple."
"Speed of delivery: We were able to reduce development time by 30%."
"OutSystems is a robust and rapid application development platform with a less steep learning curve."
"The most valuable feature of OutSystems is the drag and drop and toolchains in the small AI developing environment. Additionally, the documentation is helpful."
"It provides for faster development and better software releases."
"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."
"The ability to share a platform-agnostic common core, or business logic, enables a mobile developer to write code for all targeted mobile platforms, independent of the individual developer's specialization in iOS, Android, or Windows. This helps not only during development but also enables easier maintenance of deployed apps, since bug fixes or feature additions can be often made in the platform-agnostic layer."
"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."
"Xamarin Platform's best features are its single codebase, the support from Microsoft, and the free libraries."
"The initial setup is very simple."
"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 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."
"We very much like the XAML design techniques, multiple layout and pages, MVVMCross support, and portability across different platforms."
 

Cons

"The installation is a bit tedious."
"We'd like OutSystems to add stronger workflow-based automation similar to what Appian offers. It needs more workflow modeling and RPA features."
"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."
"I would like to see OutSystems improve its integration capabilities, especially with emerging technologies like AI and GPT."
"I would like to see improvements in versioning. It can be challenging to keep track of what changes should be committed, especially when many developers are working in one environment."
"The PDD framework can't be used for the behavioral-driven development way of working."
"There is room for improvement in technical support."
"The documentation needs to be more robust."
"They need to take a step towards independence from the UI platform. It takes a lot of time to adapt the native controls."
"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."
"There is limited support for UX widgets."
"The solution struggles a little bit with binding libraries."
"We'd like to have some chat support functionality."
"Xamarin Platform's performance base could be improved."
"From time to time, it is a bit harder to code some specific scenarios compared to the native approach."
"The Xamarin.Forms could improve."
 

Pricing and Cost Advice

"The price is okay. OutSystems isn't expensive. It's a mid-range solution."
"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 solution is 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."
"The solution is expensive. The platform is not suitable for all of my clients. I work with labor unions and other smaller organizations that would not be able to afford the platform's current pricing model. It would be beneficial if there were a scaled-down version or a tiered pricing option that would allow me to build an app or a web app that is more cost-effective for my clients. Currently, the platform's pricing is too high for many of my clients, who would not be able to afford something in the $50,000 to $100,000 range."
"It's not cheap. It's pretty expensive."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"I think the pricing for OutSystems is comparable with similar solutions. I would place it somewhere in the middle. We pay for the bundle and don't pay anything extra in terms of licensing and other fees."
"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."
"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. There is no license unless you go for some high-end enterprise features. Other than that, everything's free."
"There is no requirement for a license. It is available for free as an open-source product."
"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."
"This is an open-source solution, but there is a subscription charge to use the App Center of around $100."
"Xamarin is free, or comes with Visual Studio. Therefore, it is very profitable."
