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

"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."
"We have no complaints surrounding both the scalability and stability of this solution."
"The technical support is perfect."
"The most valuable features of OutSystems are the user interface, the flexibility to quickly integrate with almost anything in the system, and the ability to connect with databases."
"The most valuable feature of OutSystems is the drag and drop and toolchains in the small AI developing environment. Additionally, the documentation is helpful."
"Reduces the manual labor in compiling and deploying applications and generating procedural code (by reducing development bureaucracy/processes, resulting in real gains). The LifeTime Server approach, requiring just a few steps to publish applications in production environments, is fantastic."
"You can go huge - so it is definitely a scalable solution."
"One thing I like about OutSystems is that there's no lock-in. You can keep running your applications because it's on .NET and hosted centrally. That's one of the advantages I see there in terms of not having an IT strategy that has a dependency on a particular platform."
"Cross-platform development saves time and provides consistencies."
"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."
"Because of the C# programming language, we can train our .NET developers to learn Xamarin and develop mobile apps easily."
"Xamarin.Forms reduced the effort and time to build and market our solution, market our features, and get our solution into production."
"You can create one solution in C Sharp."
"You can just write one XM channel core and it'll be used for both iOS and Android."
"It brings about good code sharing strategies, which bring down cost and maintenance efforts."
"This solution is a cross-form technology, meaning that we don't have to create separate code to deploy apps across different platforms."
 

Cons

"I would like to see OutSystems improve its integration capabilities, especially with emerging technologies like AI and GPT."
"The asynchronous processing and multithreading tasks for which the current resources of the platform are very generic and not built for the end-user. Any asynchronous jobs have to be constructed with an end-user dashboard to allow inspection of the status of the activities."
"In the future with OutSystems, improvements could be made on the costing side rather than the feature side."
"The product could benefit from improved connectors to integrate with outside platforms."
"The resource availability needs to be increased."
"When shared extensions are updated, all the applications are redeployed."
"There is room for improvement in technical support."
"The installation is a bit tedious."
"The file size is a bit big, so you have to make certain layers."
"We'd like to have some chat support functionality."
"We need to think about partnering with IBM because there is a need for a big data partner; someone who has machine learning and can help us connect the app to big data."
"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."
"The major I see with Xamarin right now is that there is no visual editor"
"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."
"All Xamarin library issues need to be taken care of as a top priority."
"The architecture in the Xamarin Platform has to improve, there are some features missing."
 

Pricing and Cost Advice

"It is not an expensive product, especially if you have access to more features and deal with more projects."
"The tool’s licensing is based on the user’s usage."
"OutSystems is a good solution, but it's not cheap."
"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."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"I would rate it five to six out of ten."
"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."
"OutSystems is a very expensive solution, and it has to be cheaper."
"The product is inexpensive."
"Xamarin is free, or comes with Visual Studio. Therefore, it is very profitable."
"My company provided all the licenses that we need to support our use of Xamarin Platform."
"There's no licensing cost for Xamarin."
"This is an open-source solution, but there is a subscription charge to use the App Center of around $100."
"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 open-source, but there are fees for deployment, the API Store and Play Store, and using third-party libraries."
"Xamarin is free. There is no license unless you go for some high-end enterprise features. Other than that, everything's free."
