Helps us efficiently streamline repetitive tasks, but they could provide improved connectors to integrate with outside platforms
The OutSystems' most effective features for speeding up development cycles are the process orchestration and the drag-and-drop updating of business processes. I would recommend it to a friend or colleague, especially if they are looking for a solution that is easy to deploy and helps streamline internal processes. I rate it a six out of ten.
Prince Tiwari - PeerSpot reviewer
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

"We used almost all of the features, themes, styling guide, and approach components. They are useful in our 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."
"The most valuable feature of the solution is that it allows users to easily build applications."
"I like the mobile features the most, and there are also various features around the portal we created that I enjoy."
"The product is mostly stable."
"For me, the most valuable feature is the flexibility the tools give us to change any customer requirements on the fly, when we are in a meeting. I also like how easy it is to deploy the code between environments and how easy it is to integrate OutSystems with other systems."
"The tool makes the development process easier."
"One of the valuable features of OutSystems is the very small lead time for the delivery of projects."
"The most important impact is the reduction in product lifecycle costs."
"The native features and Xamarin Essentials package are highly valuable to us."
"Cross-platform development saves time and provides consistencies."
"Test Cloud, Calabash, SpecFlow, and Xamarin.UITest are the features which can’t be ignored because just writing code doesn’t mean your app will run flawlessly. You need to test your app on each possible device and configuration, which you can do easily."
"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."
"Xamarin.Forms exposes a complete cross-platform UI toolkit for .NET developers. The advantage is that a single team can target multiple platforms (Android, iOS, and Windows) on a shared C# codebase."
"The solution's most valuable asset is its shared code base in C# that is better for large apps."
"This solution is a cross-form technology, meaning that we don't have to create separate code to deploy apps across different platforms."
 

Cons

"In my opinion, the support and the pricing could be better."
"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."
"The tool needs to improve the efficiency of its widgets."
"The product could benefit from improved connectors to integrate with outside platforms."
"The integration Studio could be improved. It needs a tool in which we could develop C# code and then integrate into OutSystems. The application could have a better UI."
"The customer service and support are maintaining a two-day SLA for everything. 48 hours is very high."
"The resource availability needs to be increased."
"I would like to see more integration between the use of artificial intelligence to speed up the process delivery time."
"The solution struggles a little bit with binding libraries."
"The performance needs improvement, especially the dev tools, and also the ultimate output of the mobile applications."
"The worst build issue concerns are the caching process MSBuild uses to reduce the build time."
"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."
"Xamarin Platform's performance base could be improved."
"Regarding improvements, there are still some limitations with Xamarin, particularly regarding access to core functionality in Android and iOS."
"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."
 

Pricing and Cost Advice

"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
"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 was open to a deal that worked for both sides."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"There is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."
"As for licensing costs, I'm not directly involved in that aspect."
"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."
"There's no licensing cost for Xamarin."
"It saved a lot of time and resources needed to develop a cross platform mobile app."
"There is no requirement for a license. It is available for free as an open-source product."
"Xamarin is free. There is no license unless you go for some high-end enterprise features. Other than that, everything's free."
"Xamarin Platform is open-source, but there are fees for deployment, the API Store and Play Store, and using third-party libraries."
"For personal use, the Community Edition is free."
"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."
