The best thing about Outsystems is its ability to create enterprise-level applications without writing any code. We’ve built applications—even complex ones—without writing a single line of code. And if something seems impossible to achieve without code, it still gives us the option to create an extension using .NET. Review collected by and hosted on G2.com.

There is no such thing to dislike about outsystems as it simplifies things to the extent where you can ignore any drawbacks, if any Review collected by and hosted on G2.com.

OutSystems has introduced Agentic AI (Agents) with ODC. This is a new feature that gives power to developers to create AI agents for their clients to give real-time response and feedback with any service. Review collected by and hosted on G2.com.

The licensing cost is still high as small businesses can't afford to build their system using OutSystems. They should reduce the cost of licensing. Review collected by and hosted on G2.com.

What I like most about OutSystems is how it accelerates application development while still allowing the flexibility needed for complex enterprise solutions. The visual development environment significantly reduces development time, making it easier to deliver features quickly without sacrificing quality. I never imagined myself working on IT until I came a cross outsystems, because it allows you too focus on pure business Logic. Review collected by and hosted on G2.com.

One area for improvement is the merge process, which can become complex when multiple developers work on the same components, making conflict resolution more difficult than in traditional development environments, branching would be good Review collected by and hosted on G2.com.

Transforming our internal LOB applications to OutSystems has, so far, been a great move. The ability to design, build, and deploy solutions for the business with strong CX and UI is invaluable. Re-platforming many of our LOB apps into OutSystems means we can now give our employees the functionality and security they’ve always wanted, which we weren’t able to deliver with our incumbent systems.

The only downside experienced so far is that the capabilities of OS are so far reaching that some simple solutions can seem like they require more lengthy dev time. This is far outweighted however by the ability to provide more functionality than ever before to our users Review collected by and hosted on G2.com.

OutSystems enables quick application development and comes as an all-in-one bundle for deployment, with CI/CD and internal security built in. It’s easy to use and easy to get used to. I have 4 years of professional experience with it, and it’s something I naturally think about when I’m coding. Implementing logic feels straightforward, and REST integrations are simple to set up and pick up. I’ve also had quick replies from OutSystems itself when I needed support. I use OutSystems daily in my life. Review collected by and hosted on G2.com.

Sometimes an infinite loop can slip by unnoticed, and it can take a while to track down and fix. Also, the market itself is still fairly niche and not very widespread (yet), which can be a concern in this day of AI. Review collected by and hosted on G2.com.

I like that OutSystems makes it easier to create appealing UIs without complex coding, especially compared to plain ASP.NET or React. The deployment through a DTAP process with Lifetime is extremely easy and useful. I also appreciate the ability to retrieve data easily through aggregates and use advanced SQL when needed. The capability to create extensions to integrate with external environments is very beneficial. My experience with technical support is positive, with fast responses and quick solutions or workarounds. Integration with the outside environment, especially using REST services and connecting to Workday via SOAP, is well supported, with perfect help from support to convert WSDL files for Service Studio import. The initial setup was very easy, taking just a couple of days. Review collected by and hosted on G2.com.

What I miss is conditional breakpoints which are standard in Microsoft Visual Studio for over 20 years. Review collected by and hosted on G2.com.

What I like best about OutSystems is its ability to accelerate application development through a visual low-code approach while still allowing developers to add custom code when needed. It significantly reduces development time, simplifies maintenance, and enables faster delivery of business solutions. I also appreciate its strong integration capabilities, built-in deployment tools, and enterprise-grade scalability, which make it suitable for developing complex applications efficiently. Additionally, the platform’s AI-powered features and reusable components help improve productivity and collaboration between business and technical teams. Review collected by and hosted on G2.com.

One aspect of OutSystems that I find challenging is that highly customized or very complex requirements can sometimes be more difficult to implement compared to traditional coding approaches. While the platform provides great flexibility, developers may occasionally need to work around platform constraints or use custom extensions. Additionally, licensing and infrastructure costs can be a consideration for some organizations. However, these trade-offs are often outweighed by the speed of development, ease of maintenance, and overall productivity gains that OutSystems provides. Review collected by and hosted on G2.com.

What I value most about OutSystems is how quickly it can take you from concept to a production-grade application without sacrificing architectural control. In real delivery projects, the visual development model compresses what would normally be weeks of boilerplate—data models, CRUD logic, and screen scaffolding—into hours, which frees the team to focus on the business logic and the edge cases that actually matter.

The platform’s push into agentic and AI-assisted development is where it becomes genuinely compelling. Being able to delegate scaffolding, pattern generation, and repetitive integration work to AI agents inside the IDE meaningfully shortens the development lifecycle. Just as importantly, those agents operate within the guardrails of governed platform components, rather than generating free-form code that you then have to audit line by line. That balance of autonomy with enforced consistency is difficult to achieve with a traditional coding stack.

Finally, the built-in lifecycle management—environments, dependency tracking, and one-click deployment—helps those speed gains hold up at scale, instead of turning into technical debt once a project grows beyond the prototype stage. Review collected by and hosted on G2.com.

The proprietary model does imply a degree of platform commitment—reusing logic outside OutSystems isn’t always straightforward. In practice, though, this is manageable if you keep core business logic in clearly defined service layers and expose functionality through APIs. That approach keeps the architecture portable and makes the dependency a deliberate choice rather than an accident.

Licensing can also become a meaningful line item as you scale. The best way I’ve found to handle this is to be intentional about which applications truly belong on the platform—high-change, high-value apps—and to govern environment and user allocation so you’re paying for what genuinely benefits from low-code speed.

At times, highly customized requirements can stretch the visual paradigm. The platform’s extensibility (custom code, external libraries, forge components) addresses most of these cases well, and treating those extension points as a standard part of the toolkit—not merely a fallback—removes much of the friction.

On the agentic and AI tooling side, the direction looks promising and it’s improving quickly. It’s currently strongest for scaffolding and repetitive work; pairing it with clear human review for architecturally sensitive tasks lets you capture productivity gains now while the autonomy continues to mature.

I use OutSystems as a developer to create web applications for our clients, and I really appreciate how straightforward it is. The platform makes it easy to develop quickly and efficiently, allowing us to produce good-looking front ends with solid workflow logic that we can promptly ship to our clients. I like that OutSystems doesn't require much boilerplate setup since it provides default code and themes that can be overridden when needed, which means you're never forced into one set standard. Additionally, the ease of setup was impressive. Review collected by and hosted on G2.com.

The one major thing I would like is a form of branching. The one click publish is good, however, when working with bigger teams this can get clunky. Having a bit more granularity of version control would help in this regard. Maybe an option to create your own version or branch of the application which you can merge to a main branch once the code is complete. Review collected by and hosted on G2.com.

I like how it enables me to be both creative and build whole new solutions while still remaining "one toe deep" into the business side of things. For me the low code platform merges a BA role with a developer role in a way that challenges me technically while still remaining part of the analysis pipeline as well. I would not want to only write code but also refine processes, something I went to college for. This tool allows for the perfect equilibrium.

Moreover what I love is the ease of integrating different programs/third party apps and how easy it is to do. Stuff like API integrations become a cakewalk with OutSystems and it really helps that API REST is currently the most used way to integrate external data into applications Review collected by and hosted on G2.com.

Sometimes it feels like when something isn't natively supported, it need custom code and that can be quite clunky. Especially when there is not a third party tool with API integration some solutions can feel very unrefined but you have no other choice because there is no native support for it.
