In terms of speed, it is near identical to native apps, maybe slightly slower, but imperceptible to the human eye because under the hood, your Xamarin Platform codebase gets translated to native code, so it is as good as native.

Room For Improvement

OutSystems needs to enhance performance, reduce costs, improve support, and refine integration, UI, documentation, and AI capabilities.
Xamarin Platform struggles with outdated libraries, UI issues, and developer tool limitations, requiring enhancements in performance and support.
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.
Senior Technical Lead at a pharma/biotech company with 1,001-5,000 employees
It is crucial to be aware of which module corresponds to which application in real-time projects, as there are multiple applications.
Software Developer Advisor at NTT DATA Services
I would like to see more integration between the use of artificial intelligence to speed up the process delivery time.
RPA Engineer at a computer software company with 10,001+ employees
Xamarin Platform, having been discontinued a couple of years ago, is no longer compatible with the latest libraries and SDKs offered by Google and Apple.
Technical Manager at Landmark Group
 

Setup Cost

OutSystems is costly for small businesses, but valued for its robust enterprise features compared to competitors.
Xamarin Platform is open-source and free, with additional costs for enterprise features, Apple Developer Membership, and optional services.
Subsequent users can be added at an additional cost per user; exact pricing details can be found on the OutSystems site.
Software Developer Advisor at NTT DATA Services
You still have to pay Google Play Store the subscription fees and the fees to Apple for publishing, but building apps in Xamarin Platform does not require any financial investment, as long as you have Visual Studio, which is again free.
Technical Manager at Landmark Group
 

Valuable Features

OutSystems enhances productivity with one-click publishing, visual modeling, seamless integration, and flexible cross-platform support for rapid development.
Xamarin Platform enables efficient mobile app development with a single codebase, native API access, and Visual Studio integration.
We use integration extensively in OutSystems, which allows us to connect our own internal systems to our newly created system applications.
Project Manager at Centre for Content Creation
OutSystems offers a lot of reusable components and solutions that I can simply drag and drop and use, which has a significant impact on project delivery time.
RPA Engineer at a computer software company with 10,001+ employees
It is a market, ready-to-market kind of platform tool, then very much scalable for the enterprise-grade applications.
Senior Technical Lead at a pharma/biotech company with 1,001-5,000 employees
It saves development cost, and you have a single codebase instead of maintaining two codebases, one for Android and another for iOS.

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.

Unified codebase has reduced mobile development effort but now faces SDK and support limits
You can still develop public-facing apps with Xamarin Platform, but there are restrictions on Xamarin Platform App Store and Google Play that prevent you from publishing your apps because they require you to use their latest SDKs and their latest libraries. Xamarin Platform, having been discontinued a couple of years ago, is no longer compatible with the latest libraries and SDKs offered by Google and Apple. So you have to use obsolete libraries and obsolete packages, which means that when you try to publish them, your Google Play or Apple App Store will prevent you from doing that because you have not used the latest libraries. Right now, Xamarin Platform has been discontinued. Xamarin Platform had its flaws, and there were known issues. Xamarin Platform has a big community of developers, so even though there are known issues and flaws, there are known workarounds. In terms of stability, I would rank it at 7.5, but I believe 7 would be a more accurate rating, so 7 out of 10.
