Featured Reviews

Luis Gerardo Meneses Hernandez - PeerSpot reviewer
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.
Sukrut Joshi - PeerSpot reviewer
Enables users to develop applications quickly and has a responsive and helpful technical support team
The time to market is quite good. We can quickly develop an application using the tool. OutSystems is developed using .NET and Java. We can easily find technical resources who have worked on .NET and Java and leverage their previous knowledge to develop OutSystems applications. It can also be used for application development. If an end-user does not want to use the solution after two to three years, OutSystems sends the source code and the applications to the end-user. There is no dependency. It’s one of the major factors I found quite good in OutSystems.

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."
"The most valuable features of FlutterFlow are the integrations and workflows."
"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."
"The most valuable features of OutSystems are the user-friendly platform. The drag-and-drop feature is great. I have used other rapid application development tools before, but they were not as advanced as OutSystems. With the previous tools, I had to manually build certain features, but OutSystems does it automatically."
"The most important features of this tool are its visual modeling capabilities and drag and drop functionality. You can see what you are coding which makes it easy to understand and maintain. They have also created a big revolution in digital transformation by introducing native mobile app development under the same IDE."
"In terms of user support and community engagement, I rate the tool a ten out of ten."
"It is a stable solution, and the initial setup is straightforward."
"One of the valuable features of OutSystems is the very small lead time for the delivery of projects."
"It is very stable."
"The visual program of OutSystems is one of the major advantages of this solution."
"We have no complaints surrounding both the scalability and stability of this solution."
 

Cons

"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 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."
"There is room for improvement in advanced functionality so it could cater to more complex app development needs."
"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 tool needs to improve the efficiency of its widgets."
"The customer service and support are maintaining a two-day SLA for everything. 48 hours is very high."
"OutSystems does not provide any native reporting resources. All reports must be created with other tools or as a webpage."
"The solution's testing framework needs to be improved, and the workflow should be slightly more mature."
"There are not enough resources on the market."
"The cons involve delays in project timelines primarily due to the time taken in requirements refinement and challenges faced when adding new features, making it somewhat complex to manage and maintain applications as they grow in scale."
"The prices should be lower. It is a little bit too high for a small market."
 

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 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."
"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."
"It is very high price."
"Pricing could be a concern. You have to pay yearly, even after you have completed your development."
"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
"As for licensing costs, I'm not directly involved in that aspect."
"OutSystems is an expensive product. My company has to make monthly payments towards the licensing costs attached to the solution."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
