Luis Gerardo Meneses Hernandez - PeerSpot reviewer
Software developer at Apps2Go TECH
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.

Rapid delivery has transformed complex enterprise apps and supports faster cross-domain projects
Every platform or low-code platform tool is quite good in its own area, but there is always space to groom or enhance or improve. The same is with OutSystems as well. A couple of things from the integration point of view can be enhanced. If your application or the enterprise organization is tackling a huge data application where you have bulk amounts of data, it becomes a challenge for all the technologies and the same with OutSystems. You have to design your architecture in a very magnificent and decent way so that how you process your data so that load can be easily balanced. Data handling and huge data handling is a kind of challenge you may need to face. Then we have some vendor lock-in. If you are trying to migrate your application from OutSystems, then you probably get into this vendor lock-in system. Some organization may face challenges if some organization is on a small scale size. The small scale businesses may find OutSystems costly because of its high cost and pricing due to the licensing cost. Apart from that, OutSystems really plays well, and it needs a learning curve. If a traditional application or programming is there which your developers are skilled into and they are directly deployed into OutSystems, it may take some significant amount of time for them to get comfortable with OutSystems. There is a learning curve. OutSystems community is already in place, but it can more be enhanced regarding some aspects. They did organize lots of bootcamps and other user groups as well, but those can also be improved from the documentation point of view and having some integration guidebook as well. A couple of things which can be improved into OutSystems include the licensing cost, the vendor lock-in side, the learning curve, couple of integration aspects and customizations.

Quotes from Members

Pros

"It allows you to create fragments that look good and work on both mobile and web environments."
"The most valuable features of FlutterFlow are the integrations and workflows."
"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."
"The most valuable feature of OutSystems is the drag and drop and toolchains in the small AI developing environment. Additionally, the documentation is helpful."
"You can go huge - so it is definitely a scalable solution."
"It is a stable solution, and the initial setup is straightforward."
"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 allows you to do things really quickly; this product requires very little maintenance, and it is easy to do as compared to traditional programming solutions."
"OutSystems is a hybrid framework and supports my mobile and web application development needs. This means I don't have to write separate code for mobile applications. It adapts the UI and functionality, whether I'm developing for web or mobile interfaces. All I need to do is provide the layout during development."
"The technical support is perfect."
"The most important features of this tool are its visual modeling capabilities and drag and drop functionality. You can see what you are coding which makes it easy to understand and maintain. They have also created a big revolution in digital transformation by introducing native mobile app development under the same IDE."
 

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."
"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 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."
"The PDD framework can't be used for the behavioral-driven development way of working."
"When shared extensions are updated, all the applications are redeployed."
"In the future with OutSystems, improvements could be made on the costing side rather than the feature side."
"The dashboards in OutSystems could improve. There are a lot of tabs in the service center that can be confusing."
"The product could be improved if there was a shortcut, or predefined, predictable templates provided."
"I'd like to see AI features integrated into the solution."
"The cons involve delays in project timelines primarily due to the time taken in requirements refinement and challenges faced when adding new features, making it somewhat complex to manage and maintain applications as they grow in scale."
 

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."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"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."
"It's not cheap. It's pretty expensive."
"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
"OutSystems is a good solution, but it's not cheap."
"The price is okay. OutSystems isn't expensive. It's a mid-range solution."
