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

"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."
"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."
"The most valuable features of FlutterFlow are the integrations and workflows."
"Their drag-and-drop functionality is amazing."
"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."
"The integration capabilities have benefited my customers by providing many connectors out of the box, allowing for the integration of external applications or business applications."
"We find in OutSystems a great platform that enables extraction of data from multiple sources, and working with business logic to access essential information and produce process-automation at the highest level."
"It is easy to use."
"We used almost all of the features, themes, styling guide, and approach components. They are useful in our applications."
"The product is mostly stable."
"You can use this solution to build applications very rapidly."
 

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."
"We'd like OutSystems to add stronger workflow-based automation similar to what Appian offers. It needs more workflow modeling and RPA features."
"I've read that where you have large deployments, OutSystems starts to crumble a bit."
"The initial setup of OutSystems is not easy. It is a very heavy application that requires a lot of hardware and software resources."
"There are many tutorials available but they are very basic and good for learning the platform. To develop an enterprise-grade application, advanced tutorials need to be developed to help IT professionals design/develop high-quality/performance applications."
"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."
"In the future with OutSystems, improvements could be made on the costing side rather than the feature side."
"There's no exit strategy in OutSystems. If you want to leave it or want to go to another technology, you're kind of stuck, and it will cost you a huge investment to get rid of that."
"We had some lagging issues under high data loads, and the solution needed to be customized to improve this."
 

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 would rate it five to six out of ten."
"OutSystems is an expensive product. My company has to make monthly payments towards the licensing costs attached to the solution."
"I believe they have two pricing options. One is approximately $4000 USD a year and the other is approximately $10,000 USD a year."
"It's not cheap. It's pretty expensive."
"The tool’s licensing is based on the user’s usage."
"As for licensing costs, I'm not directly involved in that aspect."
"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."
"The subscription is billed on a yearly basis."
