Creates versatile applications seamlessly across platforms
I like the simplicity of making panels with Flutter. It is easy to use when you understand the code, know how to use Docs, and understand the components of Flutter. It allows you to create fragments that look good and work on both mobile and web environments. Additionally, it works for both PC and iOS devices.

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.

Pros

"FlutterFlow offers a lot, but one feature that really helps me is the debugging features that allow me to test everything on the spot. This is really helpful."
"The most valuable features of FlutterFlow are the integrations and workflows."
"I like the simplicity of making panels with Flutter."
"It allows you to create fragments that look good and work on both mobile and web environments."
"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."
"The scratch coding is useful. The solution is easy to understand."
"In terms of user support and community engagement, I rate the tool a ten out of ten."
"It is a scalable solution...The initial setup of OutSystems is easy."
"OutSystems is scalable, and we have easily managed minor escalations and added redundancy to our app server, which was simple to set up."
"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."
"Comparatively, as a low-code kind of platform, OutSystems is the most intuitive to use, but if you have an experienced programmer in Java and .NET like myself, then the other platform is probably a bit more flexible."
"Once built, web/mobile components can be reused in all new developments. In addition, the OutSystems Forge is very useful. We can exchange components and even already-built applications, reducing costs to build specific solutions."
 

Cons

"There is room for improvement in advanced functionality so it could cater to more complex app development needs."
"Scaling depends on project requirements."
"I am trying to see how it can be integrated with the backend. That said, I haven't gotten there yet."
"The UI components could be more standardized. Sometimes, for certain properties, I have to search more than I do with other platforms. With other platforms, once you know one, you know all. But with FlutterFlow, sometimes you have to look around for what you need."
"The integration Studio could be improved. It needs a tool in which we could develop C# code and then integrate into OutSystems."
"The dashboards in OutSystems could improve. There are a lot of tabs in the service center that can be confusing."
"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."
"Mobile apps need improvement."
"We had some lagging issues under high data loads, and the solution needed to be customized to improve this."
"I think OutSystems needs to improve in many areas. First, sometimes Service Studio becomes really slow and even hangs for long periods."
"Currently, in mobile applications, we don't have push notifications."
"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."
 

Pricing and Cost Advice

"I would rate the licensing costs a three out of ten, with ten being expensive and one being cheap. Currently, I use the free version."
"OutSystems is an expensive product. My company has to make monthly payments towards the licensing costs attached to the solution."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"For a single application, it's too expensive."
"OutSystems was open to a deal that worked for both sides."
"It is very high price."
"It is too expensive for small companies."
"The solution is expensive."
"Pricing could be a concern. You have to pay yearly, even after you have completed your development."
