Build custom apps faster with the right custom app builder

OutSystems is what happens when low-code meets real-world enterprise needs for building secure, scalable applications with your data, your users, and your workflows—all moving fast, without the mess.

• Full-stack capabilities with room for custom code when needed
• Enterprise-grade governance and compliance baked in
• Integrations that connect your existing systems, not replace them

For IT leaders: Build with confidence and control

You’re not just managing tech, you’re also managing expectations. From budget constraints to stakeholder demands, IT leaders are asked to be strategic, operational, and fast. OutSystems helps you balance it all.

This platform fits into your broader IT architecture with the tools, oversight, and extensibility your team needs. It supports real collaboration across IT and the business while keeping governance and security front and center.

• Define granular user roles and app access permissions
• Manage lifecycles with version control, rollback, and policy enforcement
• Ensure compliance with SOC 2, ISO, GDPR, and more
• Integrate with ERP, CRM, and legacy systems through APIs and prebuilt connectors
• Enable scalability with autoscaling, multi-experience delivery, and microservices support

You’ll reduce the total cost of ownership, move projects through your backlog faster, and support citizen developers safely, without losing sight of security or performance.

For business leaders: Get to "yes" faster

Sometimes, the hardest part isn’t building the solution, but getting it greenlit. Business users often feel stuck waiting on IT to prioritize their needs or constrained by SaaS tools that can’t flex to fit their workflows.

OutSystems empowers your team to move faster, without going rogue. It bridges the gap between business goals and technical execution.

• Launch prototypes quickly with intuitive visual tools and prebuilt templates
• Iterate based on feedback without derailing roadmaps
• Replace spreadsheets and manual workarounds with real apps
• Collaborate with IT through a shared platform that keeps data secure
• Own your data: OutSystems makes access, storage, and governance visible and controllable

You can solve real problems in your department faster, cheaper, and in a way that scales with your business.

For tech evaluators: Control without compromise

If you're vetting platforms, you’ve probably seen several tools that look great until the moment you need to customize something. OutSystems doesn’t hit that wall. It supports rapid delivery and deep extensibility.

• Architect reusable components and shared design systems
• Extend apps with custom code where necessary
• Monitor performance and logs in real time
• Integrate with your observability stack

You get the oversight and openness you’d expect from traditional dev platforms, plus the agility of low-code.

For developers: Less repetition, more creation

This is about freeing up developers rather than replacing them. No one wants to spend another sprint building a login screen or hand-coding CRUD interfaces. With OutSystems, developers can focus on solving real problems instead of the daily repetitive tasks.

• Visual IDE with full-stack extensibility
• CI/CD tools and DevOps pipelines baked in
• Component libraries to speed up delivery
• Room to inject your preferred libraries, logic, and data services

Developers stay in flow while the platform takes care of the foundation.

Conclusion: Build custom apps smarter, not slower

Custom doesn’t have to mean complex. Many platforms overpromise and underdeliver when real demands surface. But OutSystems holds up, allowing you to build custom apps that matter—securely, collaboratively, and at the speed your business needs.
