OutSystems is a low-code application development platform. Developers build complete web and mobile applications by assembling screens, logic, data and integrations visually, and the platform generates, deploys and manages the underlying code. This lets businesses deliver enterprise-grade applications much faster than with traditional hand-coding, while keeping security, scalability and maintainability built in.
Key takeaways
- OutSystems is a low-code platform for building enterprise web and mobile applications visually, with professional developers still in control of logic, data and integrations.
- It suits business-critical apps that need to ship fast: customer portals, internal workflow tools, mobile field apps and legacy modernisation.
- There are two platform generations: OutSystems 11 and the cloud-native OutSystems Developer Cloud (ODC).
- Results depend on the team: certified OutSystems developers with production experience make the biggest difference to speed and quality.
How does OutSystems work?
In traditional development, programmers hand-write front-end code, back-end code, database scripts and deployment pipelines. In OutSystems, a developer works in a visual development environment and models the same things: screens are designed by drag and drop, business logic is built as visual flows, and data is defined as entities. The platform then generates standard, optimised code, handles the database and deploys the app.
It is not "no-code". Professional developers still design architecture, write expressions and validations, and can extend the platform with custom code when needed. The difference is that the repetitive plumbing is automated, so the team spends its time on what the business actually needs.
- Visual, full-stack development: user interface, logic and data in one environment.
- Reusable components: build a module once and reuse it across apps.
- One-click deployment: move apps between development, test and production environments safely.
- Built-in security and governance: authentication, role-based access and monitoring are part of the platform.
- Integrations: connect to REST and SOAP APIs, databases and enterprise systems such as ERP and CRM.
What can you build with OutSystems?
OutSystems is designed for business applications that need to be reliable, secure and delivered quickly. Typical projects include:
- Customer and partner portals for self-service, onboarding and case tracking.
- Internal workflow applications that replace spreadsheets, email approvals and paper forms.
- Mobile apps for field teams, including offline use.
- Legacy modernisation, rebuilding ageing systems on a modern platform step by step.
- AI-powered applications that add document processing, chatbots or predictions to business processes.
AWT has delivered OutSystems applications such as supply management, loan origination, resource management and education management systems for enterprise clients.
OutSystems 11 vs OutSystems Developer Cloud (ODC)
OutSystems currently has two platform generations, and it is worth knowing which one you are using before you hire a team:
| OutSystems 11 (O11) | OutSystems Developer Cloud (ODC) | |
|---|---|---|
| What it is | The established, widely used OutSystems platform | The newer, cloud-native generation of the platform |
| Architecture | Modules and applications on a shared platform server | Independent apps and libraries running on containers in the cloud |
| Best for | Existing OutSystems estates and teams | New cloud-first initiatives and teams planning ahead |
Both are actively used. Many organisations run O11 today and plan a gradual move to ODC, so developers who understand both are especially valuable.
When is OutSystems a good fit, and when is it not?
OutSystems is a strong fit when you need several business applications delivered quickly, your backlog is growing faster than your developers can handle, you are modernising legacy systems, or you need web and mobile versions of the same app.
It may not be the best fit when you are building a simple marketing website, a graphics-heavy game, or a one-off tiny tool where a platform licence would not pay off. A good partner will tell you honestly when another approach is better.
How to get started with OutSystems
- Pick a pilot: choose one valuable but contained application to prove the approach.
- Get the right team: certified OutSystems developers plus a tech lead who understands architecture.
- Plan for scale: agree architecture, reusable components and governance early.
- Train your people: build in-house OutSystems skills alongside your delivery partner.
AWT supports each step: we provide certified OutSystems contract developers and dedicated teams, add AI to your applications, and run certification-aligned OutSystems training through Anav Academy.
Frequently asked questions
Is OutSystems a no-code platform?
No. OutSystems is a low-code platform for professional developers. Most of the application is built visually, but developers still design architecture, write logic and can extend apps with custom code when needed.
Can OutSystems build mobile apps?
Yes. OutSystems builds mobile applications as well as web applications, including apps that work offline for field teams.
Do I need certified OutSystems developers?
It is strongly recommended. Certified developers with real production experience follow platform best practices, which makes applications faster to build and easier to maintain.
What is the difference between OutSystems 11 and ODC?
OutSystems 11 is the established platform used by most existing customers. OutSystems Developer Cloud (ODC) is the newer cloud-native generation, where applications run independently on containers in the cloud.
