"Rapid Enterprise App Delivery with Scalable Architecture and Integration Power"
4/5
What do you like best about OutSystems?

What I like best about OutSystems is that it combines rapid application development with enterprise-grade capabilities. It allows me to leverage my integration and software architecture experience while delivering solutions much faster than traditional development. I especially enjoy working on integrations, designing scalable architectures, and helping organizations turn business requirements into working applications quickly and efficiently. Review collected by and hosted on G2.com.

What do you dislike about OutSystems?

One of the challenges of OutSystems is balancing the speed of low-code development with the flexibility of traditional development. While the platform accelerates delivery significantly, some advanced use cases require workarounds due to platform limitations. I also believe that successful OutSystems projects still depend heavily on good architecture, integration design, and governance, which are sometimes underestimated because of the low-code nature of the platform.

"OutSystems Makes App Building Simple and Fun—Now Even Easier with AI Help"
4/5
What do you like best about OutSystems?

The last time I've dabbled in coding was in college in early 2010's, and that was just basic C++.

With OutSystems, there's no pressure in knowing everything- they made coding simpler, easier, and more fun. With simple actions like drag and drop, you can create a web application with just about anything that you can imagine.

And they've made it easier (as if it wasn't as straightforward as before), but they've also integrated AI technology to help in development. With just a few prompts, the AI can help me create a system- point out where I got it wrong, how can I optimize it to be up to standards, and make it better.

But the best thing about OutSystems is the community. Forge components have been essential in helping further enhanced our web applications, and the community is very open and welcoming to newbies- giving insights from their experiences which is of great help to see if others have encountered the same things we have.

What do you dislike about OutSystems?

I don't think I have anything that I dislike about OutSystems so far. Review collected by and hosted on G2.com.

"Easy to Learn and Quick to Build"
3.5/5
What do you like best about OutSystems?

The ease of use and how quickly you can get a functioning product set up.

I have software development experience, and started working with OutSystems since May 1st. So far i've been surprised at how easy it is to get something up and running. Easy to learn and I think achievable enough to master Review collected by and hosted on G2.com.

What do you dislike about OutSystems?

The fact they use their own terminology for common development features (Entities for example). This is quite a minor complaint of course.

I do find the occasional bug every now and then (In O11) but nothing major or application breaking.

Sometimes you are limited to the platform of course, so when I would want to do a certain thing I have to comply by its rules or bend/break them. Review collected by and hosted on G2.com.

"Revolutionized Our Development Speed and Scalability"
5/5
What do you like best about OutSystems?

I really like the whole environment of OutSystems. The governance and infrastructure, along with the whole development pipeline, are excellent. The integration with new gen Agentic solutions is fantastic, and having governance for agents is a big plus. The speed of development is just incredible, and importantly, I never feel like I'm losing control. It's not like dealing with a black box; it integrates with whatever we need. Also, the learning curve was really easy and fast. Our architects were fully trained in OutSystems in less than three months, which is great. Review collected by and hosted on G2.com.

What do you dislike about OutSystems?

Predictability of the licensing usage is one of the main topics. The licensing is simpler compared to other technologies, but it's sometimes hard to estimate. Review collected by and hosted on G2.com.

"Strong low-code platform with a clear vision and thriving ecosystem"
4.5/5
What do you like best about OutSystems?

What stands out most about OutSystems is its ability to help organizations accelerate digital transformation while maintaining enterprise-grade quality and governance. From my perspective, the platform combines innovation, speed, and scalability in a way that appeals to both business and IT stakeholders. I am also impressed by the strength of the OutSystems community, partner ecosystem, and the company’s continuous investment in AI-driven development capabilities. Review collected by and hosted on G2.com.

What do you dislike about OutSystems?

As with many enterprise platforms, organizations need the right skills, governance, and adoption strategy to realize the full value of OutSystems. New users may face a learning curve when scaling applications across larger environments. Additionally, licensing and platform investment can be a consideration for smaller organizations, although the value proposition is often strong for companies with significant application development needs.

"Smart, Easy-to-Use App Builder with Reusable Modules and Simple REST API Integration"
4.5/5
What do you like best about OutSystems?

It’s a very smart application that feels like it’s thinking along with you, and it’s easy to use. It helps me create reusable modules, and implementing new features is very straightforward. Using REST APIs in Service Studio is also really easy, which is super nice. Especially now with Mentor, you can create screens you can show clients as a POC during sales so they can get a feel of what kind of business solution u want to make for them Review collected by and hosted on G2.com.

What do you dislike about OutSystems?

Sometimes I feel like the documentation isn’t very extensive. Searching through the community can help at times, but it’s not quite like other coding platforms. Review collected by and hosted on G2.com.

"G2 review"
5/5
What do you like best about OutSystems?

I find OutSystems to be very good in terms of developing concepts and proofs of concept in record time, which helps speed up the development and improvement of existing or new applications. It's very helpful because you don't have to worry too much about security aspects, and it allows you to quickly identify areas in the application development that need improvement or alignment with current standards. Also, the initial setup process of OutSystems was very fluid and non-intrusive, making steps from one to four very easy. Review collected by and hosted on G2.com.

What do you dislike about OutSystems?

What I see could be improved is how the application actually receives commands in terms of the type of application that you want developed. So if you give it a description in terms of the application that you want as a foundation, that part of the request-to-receiving process can be greatly improved.

"OutSystems Speeds Up Stable, Confident Testing"
4/5
What do you like best about OutSystems?

As a tester the speed of development is a aspect key for our work. If a developer is able to produce testable software quickly then we become effective. The ability of OutSystems to produce working stable software is great.

The ease of navigation, deployment and implementation allow me to perform my job faster and have great confidence in what I am testing is correct. No longer do I have to test all the edge feature that you have when testing a high code application. Review collected by and hosted on G2.com.

What do you dislike about OutSystems?

I find the design and layout of OutSystems feature can be a bit common. The developers tend use the same design and layout for all software projects. As a tester that is a little dull, but also part and parcel of the the software being quick to create.

Automation hooks and naming conventions could be easier to define to allow our automation solutions to find buttons, fields and other aspects of the page more easily. Review collected by and hosted on G2.com.

5/5
What do you like best about OutSystems?

What do you dislike about OutSystems?

The only thing that comes to mind is really the occasional workarounds needed for very specific tasks. Review collected by and hosted on G2.com.

"Fast, Beginner-Friendly Demo Building with Great Mentor and Training"
4.5/5
What do you like best about OutSystems?

Very fast and easy to build demos for our costumers. UI is easy to understand and the Mentor feature is a great help, especially for beginners. The available training and JumpStart sessions are an amazing way to enable our consultants to build knowledge fast. Review collected by and hosted on G2.com.

What do you dislike about OutSystems?

The platform and studio interfaces are only available in English. This is often a deterrent for our German-speaking customers when they want to use the platform themselves. The same issue applies to the trainings, which are also only offered in English. Review collected by and hosted on G2.com.
