Bireswar Das - PeerSpot reviewer
A low-code platform for the development of mobile and web enterprise applications
To illustrate a case, the customer initially had a private cloud, essentially a data center hosted within it. They needed a disaster recovery solution, which would involve using a public cloud. This situation led to some deployment challenges due to the hybrid nature of their setup. However, once we implemented the solution for them, they were extremely satisfied. The process was not only effective but also quite speedy. To be more precise, we completed it in around 100 days, even though they initially requested it to be done in four months. They were very pleased with the efficiency of the implementation.
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

"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."
"Refactoring with TrueChange is very simple."
"There is literally a ton of stuff it can do. It's very flexible."
"The most valuable feature of the solution is that it allows users to easily build applications."
"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."
"We can quickly develop an application using the tool."
"You can go huge - so it is definitely a scalable solution."
"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 solution's most valuable asset is its shared code base in C# that is better for large apps."
"The solution is easy to understand and has banking integrated. The shorter development time, the bugging and as well as availability of a lot of documentation on the web. Also the native integration is easy."
"Plugins like MvvmCross make a developer’s life easy."
"The platform is easy to learn as many tutorials are available on YouTube."
"Being able to use the .NET framework and platform have me creating applications better than anyone who develops on Windows."
"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 most valuable feature of the Xamarin Platform is the deployment."
"We were able to optimize the service organization for one of our clients."
 

Cons

"The tutorials for the solution should be updated."
"The latest version of the app generation tools could be more user-friendly."
"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."
"OutSystems could improve by being more like GitHub. It would be more helpful for us for division management and version control for our application."
"I like the OutSystems platform. I am working on integrating it with another platform using APIs, however, it has proven to be difficult. The main issue I am facing is obtaining authorization tokens as well as access and refresh tokens. It may be due to my lack of knowledge of APIs as it is new to me."
"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 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."
"Mobile apps should have been fully native."
"There are compatibility issues between versions of various Xamarin components."
"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 lacks in app size."
"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."
"We'd like to have some chat support functionality."
"The Xamarin.Forms could improve."
"The recent move to .NET MAUI is a big change that's affecting a lot of the good features."
 

Pricing and Cost Advice

"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."
"OutSystems was open to a deal that worked for both sides."
"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."
"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."
"There are no additional costs with the standard license."
"It is too expensive for small companies."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
"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 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."
"Xamarin Platform is a free open-source solution."
"It saved a lot of time and resources needed to develop a cross platform mobile app."
"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."
"There is no license fee because the solution is open-source."
"For personal use, the Community Edition is free."
"My company provided all the licenses that we need to support our use of Xamarin Platform."
"Xamarin is free. There is no license unless you go for some high-end enterprise features. Other than that, everything's free."
