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."
"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."
"I like the mobile features the most, and there are also various features around the portal we created that I enjoy."
"There is literally a ton of stuff it can do. It's very flexible."
"The scratch coding is useful. The solution is easy to understand."
"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."
"It is a stable solution."
"It is easy to use."
"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."
"We can do the validation before calling the API."
 

Cons

"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."
"Scaling depends on project requirements."
"There is room for improvement in advanced functionality so it could cater to more complex app development needs."
"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."
"In my opinion, the support and the pricing could be better."
"Its ability to create and run automated tasks could be better."
"I would like to see more integration between the use of artificial intelligence to speed up the process delivery time."
"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 new version could be improved."
"While I can't speak to the market impact, as a developer, I've seen significant reductions in development time across different versions of our applications. One area for improvement would be the UI controls in Service Studio. Sometimes, controls don't appear in the IDE, requiring us to check them in the web browser instead. Overall, our experience with OutSystems has been positive, though improvements in UI development would be welcomed."
"The PDD framework can't be used for the behavioral-driven development way of working."
 

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 price is okay. OutSystems isn't expensive. It's a mid-range solution."
"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
"It's not cheap. It's pretty expensive."
"OutSystems is a good solution, but it's not cheap."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"OutSystems was open to a deal that worked for both sides."
"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."
"Pricing could be a concern. You have to pay yearly, even after you have completed your development."
