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."

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

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

"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."

"It is a stable solution, and the initial setup is straightforward."

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

"It is very stable."

"It is a scalable solution...The initial setup of OutSystems is easy."

"In terms of user support and community engagement, I rate the tool a ten out of ten."

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."

"Scaling depends on project requirements."

"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."

"I would like to see improvements in versioning. It can be challenging to keep track of what changes should be committed, especially when many developers are working in one environment."

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

"I would like to see OutSystems improve its integration capabilities, especially with emerging technologies like AI and GPT."

"Mobile apps need improvement."

"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."

"It is hard to find the logic in OutSystems. From an improvement perspective, I want to be able to properly use logic in OutSystems."

"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."

"While I can't speak to the market impact, as a developer, I've seen significant reductions in development time across different versions of our applications. One area for improvement would be the UI controls in Service Studio. Sometimes, controls don't appear in the IDE, requiring us to check them in the web browser instead. Overall, our experience with OutSystems has been positive, though improvements in UI development would be welcomed."

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."

"It is too expensive for small companies."

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

"For a single application, it's too expensive."

"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."

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

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

"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
