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.

OutSystems facilitates rapid application development and effective project management

What I find valuable about OutSystems is that it has a very good learning curve for developers. Within two weeks, we can gain knowledge in OutSystems, and it is very easy to learn. With my background being .NET, OutSystems is straightforward to learn, which is beneficial. Developing applications in OutSystems is good, and the flexibility allowed by OutSystems for application development is excellent compared to my experiences with other low-code technologies, where I've faced some challenges. The clean separation of concerns in the architecture provided by OutSystems is a key benefit compared to other platforms. OutSystems integrates with our existing tech infrastructure and provides flexible integration. If we want to integrate with third-party services, OutSystems has SOAP and RESTful services that allow us to consume external services, integrate with external databases such as SQL or Oracle, and includes integration studio for writing custom .NET code. After developing a .NET component, we can reference it in service studio, creating a reference file that makes integration easy. OutSystems officially supports various integrations and also includes an API discovery tool for consuming and exposing services, providing a lot of information about incoming URLs, similar to how we use Postman.

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."

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

"It allows you to create fragments that look good and work on both mobile and web environments."

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

"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."

"I really like the one-click publish feature in OutSystems. In other development tools/languages, it's not as easy. I also like how easily I can manage all my projects in one place."

"Refactoring with TrueChange is very simple."

"Reduces the manual labor in compiling and deploying applications and generating procedural code (by reducing development bureaucracy/processes, resulting in real gains). The LifeTime Server approach, requiring just a few steps to publish applications in production environments, is fantastic."

"It is very stable."

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

"Scalability proved to be an exceptionally beneficial feature."

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."

"The integration points need to be increased. People have also started to adopt this solution for their regular needs. That means it's not only the big enterprises that are adopting this solution. There are also small and medium enterprises that are adopting it. I've read that where you have large deployments, OutSystems starts to crumble a bit. That is the idea that no customer would know at the beginning and would also not like to hit the wall there. When it is on the client, there are a lot of applications already on low-code, and then suddenly you realize that you want to do some big applications, and you face hurdles. This is the general feedback for all such platforms."

"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."

"Currently, in mobile applications, we don't have push notifications."

"I think OutSystems needs to improve in many areas. First, sometimes Service Studio becomes really slow and even hangs for long periods. Also, if I have not published my module in some time, and some kind of Service Studio exception occurs, I lose my work."

"We have performance issues while fetching bulk data."

"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."

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

"The PDD framework can't be used for the behavioral-driven development way of working."

More OutSystems cons

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."

"As for licensing costs, I'm not directly involved in that aspect."

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

"For one developer to use, the cost is around $5,000."

"The product is expensive and I would rate its pricing a seven out of ten. You need to pay a yearly subscription to use the product."

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

"There are no additional costs with the standard license."

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

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