Modern cloud-native infrastructure

OutSystems leverages Kubernetes, containers, and microservices, all on the foundation of Amazon Web Services (AWS).

Watch for low-code platforms that lock you into legacy cloud application platforms like Cloud Foundry.

Real code, not interpreted code

OutSystems generates real code–100% C#, JavaScript, and SQL–that runs and scales at native speed.

Watch out for application models that are interpreted at runtime and require more compute resources.

Unpredictable workloads? Let’s go!

OutSystems automatically scales vertically and horizontally to meet even the wildest workloads.

Look out for platforms that require manual scaling and pre-purchase of compute resources to manage unpredictable demands.

Optimized compute resources

Deploy your applications to our optimized environment without the headache of managing individual computing resources.

Review the compute requirements of other platforms to ensure they don’t need separate resources for each stage of the SDLC.

Why developers love OutSystems

"I know React, Angular and much more, but I've never implemented scripts for CI/CD, I've never developed back-end solutions or databases. Thanks to OutSystems, I am now a full-stack developer. I will never look back."

Senior Developer

Bart N. Enterprise user review on G2

"The OutSystems Community offers a lot of support. Reactions are fast and fellow developers often create little pieces of sample software in order to help. That's a very big advantage. Not only the community members but also OutSystems customer support reacts fast and is very willing to help."
