Updated on 4 Dec 2024 9 min read

The best low-code platforms offer an easy-to-use interface with intuitive controls and reusable components that help users save time and effort on app development. Platforms like OutSystems are among the top choices for enterprises and developers who want to easily build applications without compromising quality.

OutSystems offers a unified platform for low-code app design, coding, and development. The platform provides a visual development environment with drag-and-drop components, pre-built templates, and user interface elements that accelerate app development. OutSystems’ single-click deployment and guided refactoring features also decrease time to market.

Despite these benefits, OutSystems does have a few downsides, just like every other platform. For instance, non-technical users can find using some of its advanced functionalities challenging. The platform can also become slow from time to time.

While OutSystems is worth considering, users with natural reservations against some of the downsides of this platform might want to consider alternatives that might be a better fit for their app development efforts. Let’s take a look at the top OutSystems alternatives for low-code development.

"There is quite a bit of lag time on the front end, and I understand that it's doing a lot in the background, however in this day if something doesn't happen instantly it feels slow. We also use the knowledge library side, and currently you have to tag it, but it won't allow you to really search multiple words at one time, which is frustrating. So you have to tag specific words in hopes that people will search for the right word."

"ServiceNow has a steep learning curve, and I'm not sure how necessary it is. There are a lot of features sure, but finding what you need can be very difficult at times. If I know exactly what I'm looking for, it can be easy, but if I don't remember if something was an 'Incident', Request, change, or something else, it can be very difficult for me to find. I don't see an easy way to just view everything that's assigned to me, regardless of what it is."
