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.

"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."

Cons

"There is room for improvement in advanced functionality so it could cater to more complex app development needs."
"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."
"I am trying to see how it can be integrated with the backend. That said, I haven't gotten there yet."
"Scaling depends on project requirements."
"The PDD framework can't be used for the behavioral-driven development way of working."
"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."
"We have performance issues while fetching bulk data."
"The documentation needs to be more robust."
"The resource availability needs to be increased."
"I think OutSystems needs to improve in many areas. First, sometimes Service Studio becomes really slow and even hangs for long periods."
"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."
"The initial setup of OutSystems is not easy. It is a very heavy application that requires a lot of hardware and software resources."
 

Pricing and Cost Advice

"As for licensing costs, I'm not directly involved in that aspect."
"There are no additional costs with the standard license."
"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
"It is very high price."
"OutSystems was open to a deal that worked for both sides."
"It's not cheap. It's pretty expensive."
"There is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."
"For a single application, it's too expensive."
