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.
DhrubajyotiBiswas - PeerSpot reviewer
Helps us efficiently streamline repetitive tasks, but they could provide improved connectors to integrate with outside platforms
The OutSystems' most effective features for speeding up development cycles are the process orchestration and the drag-and-drop updating of business processes. I would recommend it to a friend or colleague, especially if they are looking for a solution that is easy to deploy and helps streamline internal processes. I rate it a six out of ten.

Quotes from Members

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

Pros

"The most valuable features of FlutterFlow are the integrations and workflows."
"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."
"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 really like the one-click publish feature in OutSystems. In other development tools/languages, it's not as easy. I also like how easily I can manage all my projects in one place."
"We have no complaints surrounding both the scalability and stability of this solution."
"The most valuable features of OutSystems are the user interface, the flexibility to quickly integrate with almost anything in the system, and the ability to connect with databases."
"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."
"The most valuable feature of OutSystems is the drag and drop and toolchains in the small AI developing environment. Additionally, the documentation is helpful."
"Once built, web/mobile components can be reused in all new developments. In addition, the OutSystems Forge is very useful. We can exchange components and even already-built applications, reducing costs to build specific solutions."
"It provides for faster development and better software releases."
"I like the mobile features the most, and there are also various features around the portal we created that I enjoy."
 

Cons

"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 is room for improvement in advanced functionality so it could cater to more complex app development needs."
"Scaling depends on project requirements."
"The integration points need to be increased. People have also started to adopt this solution for their regular needs. That means it's not only the big enterprises that are adopting this solution. There are also small and medium enterprises that are adopting it. I've read that where you have large deployments, OutSystems starts to crumble a bit. That is the idea that no customer would know at the beginning and would also not like to hit the wall there. When it is on the client, there are a lot of applications already on low-code, and then suddenly you realize that you want to do some big applications, and you face hurdles. This is the general feedback for all such platforms."
"It is hard to find the logic in OutSystems. From an improvement perspective, I want to be able to properly use logic in OutSystems."
"The integration Studio could be improved. It needs a tool in which we could develop C# code and then integrate into OutSystems. The application could have a better UI."
"When shared extensions are updated, all the applications are redeployed."
"In OutSystems, cloud management is an area of concern where improvements are required."
"The dashboards in OutSystems could improve. There are a lot of tabs in the service center that can be confusing."
"The latest version of the app generation tools could be more user-friendly."
"Since we first started using OutSystems, they switched their language support from Java and .NET to .NET only, which was a bit of a surprise. Their language support could be better in this sense, although on our resource side it is now a bit more flexible."
 

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 subscription is billed on a yearly basis."
"It is still very expensive, so small companies can’t generally afford it... Still, the time saving on development and delivery is worth the value."
"It's not cheap. It's pretty expensive."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
"OutSystems is a good solution, but it's not cheap."
"Pricing could be a concern. You have to pay yearly, even after you have completed your development."
"I would rate it five to six out of ten."
"As for licensing costs, I'm not directly involved in that aspect."
