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.

OutSystems is a robust and rapid application development platform with a less steep learning curve.

You can go huge - so it is definitely a scalable solution.

One thing I like about OutSystems is that there's no lock-in. You can keep running your applications because it's on .NET and hosted centrally. That's one of the advantages I see there in terms of not having an IT strategy that has a dependency on a particular platform.

Let's assume a project in .NET, native .NET, or Java takes around 12 months. In OutSystems, we can build that application in four to five months.

OutSystems does not provide any native reporting resources. All reports must be created with other tools or as a webpage.

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.

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

It needs improvement in the AI capability.

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.

The solution is costly.
