Software developer at Apps2Go TECH
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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I like the simplicity of making panels with Flutter."
"The most valuable features of FlutterFlow are the integrations and workflows."
"It allows you to create fragments that look good and work on both mobile and web environments."
"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 feature of OutSystems with discipline and the development processes. Instead of each developer doing tasks on their own with their own approach, et cetera, the solution would help bring some organization to the development process."
"It provides for faster development and better software releases."
"Our previous solution had other overheads such as release management, version management, code management, monitoring, etc., all of which are built-in with OutSystems."
"The most valuable feature is Agile development. I love that you save a lot of time on development and can focus on logic and business requirements."
"It is very stable."
"We can do the validation before calling the API."
"It is a scalable solution...The initial setup of OutSystems is easy."
"The OutSystems' most effective features for speeding up development cycles are the process orchestration and the drag-and-drop updating of business processes."
 

Cons

"Scaling depends on project requirements."
"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."
"There are not enough resources on the market."
"It needs improvement in the AI capability."
"It is hard to find the logic in OutSystems. From an improvement perspective, I want to be able to properly use logic in OutSystems."
"There is room for improvement in technical support."
"Mobile apps should have been fully native."
"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."
"It's difficult to do the component version control. I would like them to add more studying materials."
"The largest obstacle currently associated with OutSystems is its high cost and limited availability of skilled personnel. Despite being a rapid application development platform, having a highly skilled individual familiar with the platform can be much more beneficial than an inexperienced individual. Because there is a shortage of people with the necessary OutSystems skills, utilizing the platform can become expensive. This makes little sense, considering that a rapid application development platform should be accessible to the average person. However, having a highly skilled individual can greatly increase productivity, making the cost worthwhile."
 

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."
"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."
"OutSystems is a good solution, but it's not cheap."
"The solution is expensive."
"There is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."
"The tool’s licensing is based on the user’s usage."
"The price is okay. OutSystems isn't expensive. It's a mid-range solution."
"OutSystems was open to a deal that worked for both sides."
