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

"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."
"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."
"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."
"The solution helps to build mobile and web applications on SOAP and REST. You can integrate it with backend systems by submitting a code."
"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."
"For me, the most valuable feature is the flexibility the tools give us to change any customer requirements on the fly, when we are in a meeting. I also like how easy it is to deploy the code between environments and how easy it is to integrate OutSystems with other systems."
"Their out-of-the-box UI is quite good."
"Speed of delivery: We were able to reduce development time by 30%."
"The drag-and-drop feature is very valuable."
"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."
 

Cons

"I am trying to see how it can be integrated with the backend. That said, I haven't gotten there yet."
"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 is room for improvement in advanced functionality so it could cater to more complex app development needs."
"I have difficulty in using several new features. Some of the product's features are tricky to use as well."
"The solution is costly."
"There are not enough resources on the market."
"OutSystems does not provide any native reporting resources. All reports must be created with other tools or as a webpage."
"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."
"The dashboards in OutSystems could improve. There are a lot of tabs in the service center that can be confusing."
"The tool needs to improve the efficiency of its widgets."
"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."
"OutSystems is a very expensive solution, and it has to be cheaper."
"The price is okay. OutSystems isn't expensive. It's a mid-range solution."
"As for licensing costs, I'm not directly involved in that aspect."
"OutSystems is expensive, and they changed the pricing model in the last couple of years. It's changing too much and it's becoming unstable. They are constantly shifting their prices based on users, courses, and other factors."
"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."
"OutSystems was open to a deal that worked for both sides."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"It's not cheap. It's pretty expensive."
