Simplifies integrations, accelerates development timelines, and offers a good MVP
We integrate FlutterFlow into our app development process by first developing the code using the enterprise ID. Once the code is ready, we preview it and then download it. We have built a CI process where the code, once pushed to the gate, is processed by CI actions to generate the appropriate output, whether it is an IPA or APK file. While FlutterFlow currently focuses on website development, we write the code in a way that allows us to adapt it for mobile apps as well. We maintain a unified codebase for all three platforms, ensuring consistency and efficiency in our development workflow. FlutterFlow accelerated my development timeline on a project where I needed a simple website with basic navigation and form submissions. While it lacks advanced design pattern options and some features are still maturing, it simplifies integration and speeds up development. FlutterFlow's UI design capabilities have significantly impacted my app development by allowing me to communicate marketing concepts more effectively through visual flow. Every feature in FlutterFlow, from screen design to integrations, has been valuable for my development efforts. However, having better support for multiple design patterns and ensuring compatibility with custom changes would greatly improve the development experience. Overall, I would rate FlutterFlow as an eight out of ten.

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."
"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."
"The most valuable feature of OutSystems with discipline and the development processes. Instead of each developer doing tasks on their own with their own approach, et cetera, the solution would help bring some organization to the development process."
"Our previous solution had other overheads such as release management, version management, code management, monitoring, etc., all of which are built-in with OutSystems."
"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 OutSystems' most effective features for speeding up development cycles are the process orchestration and the drag-and-drop updating of business processes."
"Their out-of-the-box UI is quite good."
"The integration capabilities have benefited my customers by providing many connectors out of the box, allowing for the integration of external applications or business applications."
"One of the valuable features of OutSystems is the very small lead time for the delivery of projects."
"The most valuable features of OutSystems are the user-friendly platform. The drag-and-drop feature is great. I have used other rapid application development tools before, but they were not as advanced as OutSystems. With the previous tools, I had to manually build certain features, but OutSystems does it automatically."
 

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."
"The tool needs to improve the efficiency of its widgets."
"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."
"We'd like OutSystems to add stronger workflow-based automation similar to what Appian offers. It needs more workflow modeling and RPA features."
"Its ability to create and run automated tasks could be better."
"The PDD framework can't be used for the behavioral-driven development way of working."
"I would like to see OutSystems improve its integration capabilities, especially with emerging technologies like AI and GPT."
"Writing custom code still needs to be done via Integration Studio. This might have been added to the IDE."
"Currently, in mobile applications, we don't have push notifications."
 

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 was open to a deal that worked for both sides."
"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."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
"Pricing could be a concern. You have to pay yearly, even after you have completed your development."
"It's not cheap. It's pretty expensive."
"OutSystems is a very expensive solution, and it has to be cheaper."
"For a single application, it's too expensive."
