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.
Bireswar Das - PeerSpot reviewer
A low-code platform for the development of mobile and web enterprise applications
To illustrate a case, the customer initially had a private cloud, essentially a data center hosted within it. They needed a disaster recovery solution, which would involve using a public cloud. This situation led to some deployment challenges due to the hybrid nature of their setup. However, once we implemented the solution for them, they were extremely satisfied. The process was not only effective but also quite speedy. To be more precise, we completed it in around 100 days, even though they initially requested it to be done in four months. They were very pleased with the efficiency of the implementation.

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."
"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 like the simplicity of making panels with Flutter."
"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."
"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."
"It is easy to use."
"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."
"In terms of user support and community engagement, I rate the tool a ten out of ten."
"Refactoring with TrueChange is very simple."
"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 scratch coding is useful. The solution is easy to understand."
 

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."
"There are not enough resources on the market."
"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."
"We have performance issues while fetching bulk data."
"The documentation needs to be more robust."
"We'd like OutSystems to add stronger workflow-based automation similar to what Appian offers. It needs more workflow modeling and RPA features."
"The PDD framework can't be used for the behavioral-driven development way of working."
"It is hard to find the logic in OutSystems. From an improvement perspective, I want to be able to properly use logic in OutSystems."
"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."
"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."
"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."
"For one developer to use, the cost is around $5,000."
"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."
"Pricing could be a concern. You have to pay yearly, even after you have completed your development."
"There is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."
"OutSystems is a good solution, but it's not cheap."
