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

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."

"I like the simplicity of making panels with Flutter."

"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."

"The most valuable feature is Agile development. I love that you save a lot of time on development and can focus on logic and business requirements."

"The flow editor is the most valuable feature. It is simple and intuitive, and it can guide you step-by-step."

"The architecture of OutSystems is quite simple, and the features are similar to Mendix's. OutSystems has connectors for different enterprise apps and solid reporting capabilities. You can also integrate with any content management platform like SharePoint or Adobe Enterprise Manager, or something like that. You can also create and integrate workflows."

"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."

"Fast for server-side development."

"Speed of delivery: We were able to reduce development time by 30%."

"OutSystems is a really good platform to work upon."

"There is literally a ton of stuff it can do. It's very flexible."

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."

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

"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."

"It needs improvement in the AI capability."

"The dashboards in OutSystems could improve. There are a lot of tabs in the service center that can be confusing."

"The product could benefit from improved connectors to integrate with outside platforms."

"Writing custom code still needs to be done via Integration Studio. This might have been added to the IDE."

"The dashboards in OutSystems could improve. There are a lot of tabs in the service center that can be confusing."

"OutSystems could improve by being more like GitHub. It would be more helpful for us for division management and version control for our application."

"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 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."

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 tool’s licensing is based on the user’s usage."

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

"OutSystems is a very expensive solution, and it has to be cheaper."

"There is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."

"It's not cheap. It's pretty expensive."

"The price is okay. OutSystems isn't expensive. It's a mid-range solution."

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

"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."
