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

"It allows you to create fragments that look good and work on both mobile and web environments."
"I like the simplicity of making panels with Flutter."
"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."
"The product is mostly stable."
"Setup is easy, the solution is also easy to learn and there is a lot of community support on forums to help."
"The scalability of OutSystems is very good, it scales automatically very useful for us."
"OutSystems is a low-code solution. Most features are like drag-and-drop, so it's pretty easy to work. Thus it helps the organization by saving time for developers."
"The solution is all-encompassing and very easy to use with its drag-and-drop feature."
"Their drag-and-drop functionality is amazing."
"The OutSystems' most effective features for speeding up development cycles are the process orchestration and the drag-and-drop updating of business processes."
"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."
 

Cons

"I am trying to see how it can be integrated with the backend. That said, I haven't gotten there yet."
"There is room for improvement in advanced functionality so it could cater to more complex app development needs."
"Scaling depends on project requirements."
"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."
"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."
"Technical support would get a three out of five, as there is some wait time involved and some solutions were not adequate."
"The latest version of the app generation tools could be more user-friendly."
"We haven't yet reached the level that we need to seriously consider scaling, but from my experience it isn't so easy to scale any kind of closed platform where you start without the source."
"I would like to see OutSystems improve its integration capabilities, especially with emerging technologies like AI and GPT."
"One of the biggest areas for improvement is that every time an existing data element is modified, it creates a new data element. It doesn't really modify that particular data element. So, a user has to follow an extra step of removing the existing data element and bringing in the new and modified data element that is being added, which sort of goes into negative productivity."
"The cost of the product is very high and would price out smaller organizations."
"I have difficulty in using several new features. Some of the product's features are tricky to use as well."
 

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."
"I believe they have two pricing options. One is approximately $4000 USD a year and the other is approximately $10,000 USD a year."
"OutSystems is a good solution, but it's not cheap."
"OutSystems is expensive, and they changed the pricing model in the last couple of years. It's changing too much and it's becoming unstable. They are constantly shifting their prices based on users, courses, and other factors."
"The product is expensive and I would rate its pricing a seven out of ten. You need to pay a yearly subscription to use the product."
"As for licensing costs, I'm not directly involved in that aspect."
"For one developer to use, the cost is around $5,000."
"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."
