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."
"It allows you to create fragments that look good and work on both mobile and web environments."
"I like the simplicity of making panels with Flutter."
"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."
"It is easy to use."
"We can quickly develop an application using the tool."
"OutSystems is easy to use."
"It is a stable solution, and the initial setup is straightforward."
"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."
"Integrations with external systems with SOAP and REST are easy to implement off-the-shelf, but a developer can always implement specific libraries for other integrations."
"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 flow editor is the most valuable feature. It is simple and intuitive, and it can guide you step-by-step."
 

Cons

"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."
"There is room for improvement in advanced functionality so it could cater to more complex app development needs."
"The product could be improved if there was a shortcut, or predefined, predictable templates provided."
"It's difficult to do the component version control. I would like them to add more studying materials."
"The asynchronous processing and multithreading tasks for which the current resources of the platform are very generic and not built for the end-user. Any asynchronous jobs have to be constructed with an end-user dashboard to allow inspection of the status of the activities."
"OutSystems could improve by being more like GitHub. It would be more helpful for us for division management and version control for our application."
"I'd like to see AI features integrated into the solution."
"The technical features are good, but the actual commercialization is out of reach."
"We had some lagging issues under high data loads, and the solution needed to be customized to improve this."
"The product could benefit from improved connectors to integrate with outside platforms."
 

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."
"For a single application, it's too expensive."
"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
"I would rate it five to six out of ten."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"The tool’s licensing is based on the user’s usage."
"The solution is expensive."
"OutSystems is a good solution, but it's not cheap."
"It is very high price."
