Great user acceptance and reliability, multiple teams not required, with prompt customer service
As a developer, I would say one of the improvements is more plugins. More plugins give you the ability to do more interactions with the framework over the library. As a user, I would say more flexibility in terms of look and feel. So far Ionic is very fluid. You might not really know, it is web-based technology. I know recently it has gone through a lot of updates, but it can also be improved and become stronger. Ionic allows you to get the best customization ever, but there is nothing like having more. The more customization you get, the easier it is for you to be able to build more quality apps.

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

"It's very flexible for UI development."
"What I like the most about Ionic is live reloading, which enables us to develop new features without having to build the application again and re-check the functionality."
"With the Capacitor feature, you have access to the native attributes of your phone such as your camera. This makes work a lot easier."
"The solution can support many languages."
"The most valuable feature is the one code deployed to all solutions, which means you do not need to have multiple teams."
"Because it's a hybrid mobile app framework, it is easy for us to develop iOS as well as Android apps for our customers with the same resource skills. We didn't have to have separate iOS teams and Android teams to build the apps. We still have to use the Apple Xcode for iOS, but the main development happens with JavaScript, HTML, and CSS. We don't have to write separate code bases in scripts for iOS and Android. We create apps using web-based technology."
"Being able to have one set of code is valuable. I don't have to recode for different platforms. I don't have to recode for Xcode, Angular, or Android. So, the biggest feature for me is that it's a hybrid system, and I can have one set of code, and then the tool sets that are in there convert my code for Xcode or Play Store. It makes work a lot easier."
"Ionic's best feature is that it's not necessary to write your own custom codes as all the hybrid is provided by Angular."
"OutSystems' low-cost approach has positively impacted our productivity, because we were able to develop faster with OutSystems, enabling us to implement many changes during our sprint."
"Our previous solution had other overheads such as release management, version management, code management, monitoring, etc., all of which are built-in with OutSystems."
"OutSystems is easy to use."
"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."
"OutSystems is a hybrid framework and supports my mobile and web application development needs. This means I don't have to write separate code for mobile applications. It adapts the UI and functionality, whether I'm developing for web or mobile interfaces. All I need to do is provide the layout during development."
"The scratch coding is useful. The solution is easy to understand."
"The tool makes the development process easier."
"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."
"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 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."
"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."
"The initial setup is very simple."
"For me, developing apps for iOS and Android is a dream came true, without migrating to Objective-C or Java. Xamarin enables me to do so."
"You can just write one XM channel core and it'll be used for both iOS and Android."
"You can create one solution in C Sharp."
"The technical support is very good and it's close to native."
 

Cons

"In a future release, we would like to have a little more support for the desktop environment. Currently it is still focused on mobile devices."
"It would be better if it had a speed niche system. There are a lot of things we need that weren't in the latest version. But I think they will be adding something."
"The documentation could be improved."
"There is a lack of a community environment."
"There could be better support for augmented reality and other things. Geolocation and background app activity are some of the things that are a little more clumsy at the moment and could be improved."
"Ionic would be improved with dynamic design features."
"Ionic's UI component doesn't always look like the native mobile app."
"As a developer, I would say one of the improvements is more plugins."
"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."
"It's difficult to do the component version control. I would like them to add more studying materials."
"While I can't speak to the market impact, as a developer, I've seen significant reductions in development time across different versions of our applications. One area for improvement would be the UI controls in Service Studio. Sometimes, controls don't appear in the IDE, requiring us to check them in the web browser instead. Overall, our experience with OutSystems has been positive, though improvements in UI development would be welcomed."
"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."
"In the future with OutSystems, improvements could be made on the costing side rather than the feature side."
"The cons involve delays in project timelines primarily due to the time taken in requirements refinement and challenges faced when adding new features, making it somewhat complex to manage and maintain applications as they grow in scale."
"It is hard to find the logic in OutSystems. From an improvement perspective, I want to be able to properly use logic in OutSystems."
"The dashboards in OutSystems could improve. There are a lot of tabs in the service center that can be confusing."
"The android application compilation time needs to be reduced."
"There are compatibility issues between versions of various Xamarin components."
"I would like to see hot reload, similar to what Flutter has out-of-the-box. There is "Live Reload" but it’s still in preview and was only recently announced."
"The worst build issue concerns are the caching process MSBuild uses to reduce the build time."
"Needs to improve the customization of its screens."
"The file size is a bit big, so you have to make certain layers."
"Xamarin Platform lacks in app size."
"The problem that I faced was that the communication, the roles, and the responsibilities, weren't defined between Microsoft and Xamarin."
 

Pricing and Cost Advice

"Ionic is an open source solution, and there are no hidden fees."
"You can use the free version, but if you still want to buy it, the price starts from $499/month."
"We pay 50,000 dinars per month."
"The solution's open source option is free with no licensing fees."
"You don't have to pay anything except for certain projects. For example, Appflow has some costs related to it but you don't have to use it. You can also pay for extra support."
"I think most of the plugins for Ionic are open source, and you can do a lot with many of the basic features. However, if you need to use a premium plugin for something like extra scroll list functionality, Ionic will ask for a certain sum of money."
"The starting cost for the enterprise option is around one hundred dollars per month."
"Ionic is an open-source solution, it is free."
"OutSystems is an expensive product. My company has to make monthly payments towards the licensing costs attached to the solution."
