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

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."

"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."

"The most valuable features of FlutterFlow are the integrations and workflows."

"The solution is stable and doesn't require many server resources, so I don't think there are stability issues."

"It is very stable."

"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."

"The most valuable feature of the solution is that it allows users to easily build applications."

"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 drag-and-drop feature is very valuable."

"It is much easier to develop applications with the product’s IDE."

"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."

More OutSystems pros

Cons

"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."

"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."

"There is room for improvement in advanced functionality so it could cater to more complex app development needs."

"The tool's weakness is its focus on the solution only. Other than that, it's pretty easy to use for both technical and non-technical people. However, the tool lags in automation. For instance, we've used Python for scraping and other automated tasks. So, I believe automation is an area where it could improve."

"The solution is costly."

"When shared extensions are updated, all the applications are redeployed."

"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."

"One of the things that they could do a little better is the performance speed of the UI refresh; it sometimes seems a little choppy, and I would have to reload the same page a couple of times to get the reflection of the right information."

"The initial setup of OutSystems is not easy. It is a very heavy application that requires a lot of hardware and software resources."

"In OutSystems, cloud management is an area of concern where improvements are required."

"There's no exit strategy in OutSystems. If you want to leave it or want to go to another technology, you're kind of stuck, and it will cost you a huge investment to get rid of that."

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."

"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."

"The subscription is billed on a yearly basis."

"I believe they have two pricing options. One is approximately $4000 USD a year and the other is approximately $10,000 USD a year."

"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."

"It is very high price."

"It is not an expensive product, especially if you have access to more features and deal with more projects."

"The solution is expensive."

"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
