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

"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 features of FlutterFlow are the integrations and workflows."
"I like the simplicity of making panels with Flutter."
"We have no complaints surrounding both the scalability and stability of this solution."
"One thing I like about OutSystems is that there's no lock-in. You can keep running your applications because it's on .NET and hosted centrally. That's one of the advantages I see there in terms of not having an IT strategy that has a dependency on a particular platform."
"We've used features like batch processing timers, components, and integrations with other systems like SAP, which have accelerated our development process.In terms of productivity, we've seen a 30 percent reduction in screen design time and an additional 10 percent improvement when implementing client requirements. OutSystems' integration capabilities have significantly enhanced our app's functionality, making it quicker and easier to connect with other systems."
"We can quickly develop an application using the tool."
"OutSystems is easy to use."
"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."
"It is much easier to develop applications with the product’s IDE."
"It is a stable solution, and the initial setup is straightforward."
 

Cons

"There is room for improvement in advanced functionality so it could cater to more complex app development needs."
"Scaling depends on project requirements."
"I am trying to see how it can be integrated with the backend. That said, I haven't gotten there yet."
"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."
"The installation is a bit tedious."
"The solution is costly."
"The latest version of the app generation tools could be more user-friendly."
"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."
"I would like to see improvements in versioning. It can be challenging to keep track of what changes should be committed, especially when many developers are working in one environment."
"Writing custom code still needs to be done via Integration Studio. This might have been added to the IDE."
"We have performance issues while fetching bulk data."
"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."
 

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 think the pricing for OutSystems is comparable with similar solutions. I would place it somewhere in the middle. We pay for the bundle and don't pay anything extra in terms of licensing and other fees."
"The solution is expensive."
"The tool’s licensing is based on the user’s usage."
"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."
"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."
"There are no additional costs with the standard license."
"It's not cheap. It's pretty expensive."
"The subscription is billed on a yearly basis."
