“The Data Fabric is what finally won me over. As opposed to having to migrate data out of your CRM or other APIs or legacy databases, you simply create a virtualized representation of all of the data types you want to work with and then use SQL to query it as if the data were already merged together. Sounds too good to be true, but it generally works. Development speed — yes, it is real. The amount of boilerplate code and compile times have been removed and you simply log in and begin developing, and something functional appears quickly.”

“I appreciate OutSystems for its fast time to production, which makes it easy to create, test, and deploy applications quickly. I love that it's a full-stack solution that allows me to work within one environment to build and complete applications, as well as write mobile and reactive websites and processes. I find the drag-and-drop widgets particularly helpful because they build complexity into them, making complex tasks easy. Access to the Forge is another feature I value, as it provides almost anything needed for specialty projects.”

“One of the most noticeable improvements recently is the stronger focus on AI-powered development. Features that support automation and intelligent workflows make it easier to build smarter applications with less effort. Along with this, the mobile development experience has improved with a more modern runtime and better-performing UI components, making apps feel smoother and more native.”

“I find OutSystems' customer service amazing. They are very good to work with, being very kind, responsive, and always quickly resolving any issues. It's impressive that they waste no time getting the right people involved to solve issues quickly and develop what we need rapidly. They are extremely fast with issue resolution, and any time a problem pops up, they escalate and solve it faster than any other vendor. I also appreciate that with the support from OutSystems' professional services team, even a complex setup process went smoothly. It's great that OutSystems provides automated onboarding, which shortens the manual work required and decreases the time to onboard an account, accelerating speed to revenue.”

"What sets OutSystems apart from many low-code platforms is that it is not limited to tactical solutions. We have used it to build mission-critical, enterprise-scale applications involving complex business logic, integration with multiple backend systems and strict non-functional requirements, including large governance projects. The platform scales nicely both technically and organisationally, making it a versatile ecosystem. Recent advancements around cloud native architecture and AI assisted development via Mentor have further strengthened its position as a future ready platform."

"[OutSystems] abstracts the entire infrastructure operations layer while accelerating the full SDLC with its low-code, decade-long knowledge. At the same time, it stays HIPAA- and FedRAMP-compliant on the fly. It also works as a strong layer above the agentic frameworks on the market, thanks to its plug-and-play connectors whil allowing to easily switch to your own ai models and bringing your own keys. Their tutorials, certifications and community are a very strong driver."

Frequently asked questions

How does OutSystems solve the problem of vendor lock-in?

OutSystems uses an open, standards-based architecture that helps organizations maintain transparency, long-term control, and flexibility while reducing vendor lock-in concerns. Agentic applications are built on standard, inspectable technologies such as C#, helping teams align with existing security, integration, and DevSecOps practices rather than relying on black-box systems.

Whether deployed in the public cloud, a sovereign local cloud, or on-premises, OutSystems gives organizations the flexibility to support their infrastructure, compliance, and data sovereignty requirements while maintaining long-term control over their applications and environments.

How scalable is OutSystems?

OutSystems is built for enterprise scale. Organizations use it to power mission-critical AI, modernize complex operations, and support growing demand across regions, business units, and digital channels.

The platform is designed to scale both agentic applications and agentic systems. In OutSystems Developer Cloud (ODC), compute and data resources automatically adjust in real time to handle changing workloads without manual infrastructure tuning. A distributed architecture with built-in load balancing and optimized identity and data services helps maintain consistent performance and operational efficiency as complexity and concurrency grow.

Does OutSystems support the creation of fully customized apps?

Yes. OutSystems is built for organizations that need custom applications and AI agents—not one-size-fits-all templates. Teams can create customized, pixel-perfect user experiences, unique workflows, complex integrations, highly specific business logic, and tailored agentic experiences while accelerating delivery with visual development and reusable components. Organizations also have access to Forge, a repository of reusable open-code modules, connectors, UI components, and business solutions that can help accelerate application delivery.

That means you can build bespoke solutions with the speed benefits of modern development platforms while maintaining the flexibility often associated with traditional coding. Many enterprises use OutSystems for specialized customer experiences, internal operations, industry-specific applications, and agentic workflows.

Which is better, Mendix or OutSystems?

The right choice depends on your priorities. Organizations comparing Mendix and OutSystems often evaluate speed, governance, customization, scalability, AI readiness, and total cost of ownership. OutSystems is a strong choice for enterprises that need custom, mission-critical applications and governed AI innovation.

How does OutSystems licensing model work?

OutSystems licensing is designed to scale with your business needs. Plans align with factors such as application complexity, number of users, environments, deployment needs, compute resources, and enterprise requirements rather than charging separately for every feature or tool.

This gives organizations flexibility to start with current priorities, then expand as adoption grows. For teams evaluating options, OutSystems experts can help map the right edition and licensing structure based on your use case, scale, and goals.
