Frequently asked questions about OutSystems
What is OutSystems?
OutSystems is a leading AI development platform built for the enterprise that empowers organizations to rapidly build custom applications and AI agents for mission-critical business functions. It combines low-code visual development with AI-powered capabilities including generative AI and agentic AI, enabling software to be built up to 10x faster than traditional development while maintaining enterprise-grade security and governance.
How does OutSystems AI Agent Workbench work?
Agent Workbench enables enterprises to design, deploy, and oversee AI agents on a unified platform. It allows organizations to transform existing business applications, workflows, and tools into intelligent agentic systems capable of reasoning, planning, and taking action. The platform supports multi-agent workflows where different AI agents collaborate on complex tasks in parallel, sequential, or hierarchical configurations, with built-in human intervention mechanisms for escalation when agent capabilities reach their limits.
Is OutSystems free to use?
Yes, OutSystems offers a free plan that includes basic features, limited storage, community support, and access for 1-5 team members. The free plan is available indefinitely with no credit card required and is generous enough for individual use. For more advanced functionality, team collaboration, and enterprise features, paid Standard and Enterprise plans are available through custom pricing by contacting sales.
What types of applications can I build with OutSystems?
OutSystems enables full-stack development of enterprise-grade mobile and web applications. You can build everything from customer-facing mobile apps and reactive web applications to mission-critical enterprise systems, internal process automation tools, customer service portals, field service applications, IT support systems, and intelligent knowledge retrieval systems. The platform supports both new applications and modernization of legacy systems.
Does OutSystems integrate with existing systems?
Yes, OutSystems easily integrates with existing systems including enterprise data sources, relational databases, data lakes, and knowledge retrieval systems like Amazon Kendra and Azure AI Search. The platform connects to diverse enterprise data through a unified data fabric approach. It also integrates with custom AI models and third-party AI providers including Azure OpenAI and AWS Bedrock, allowing organizations to maintain flexibility in their AI vendor relationships.
Is OutSystems suitable for non-technical users?
OutSystems is primarily designed for professional developers and IT teams, though its visual low-code interface does enable citizen developers to participate. However, there is a steep learning curve - low-code does not automatically let non-technical teams drag and drop to build anything useful without training. Non-technical users may need training in sound software engineering practices to avoid creating tangled messes with copy-paste patterns.
How does OutSystems handle AI governance and security?
OutSystems provides enterprise-grade governance with 91% customer satisfaction for data privacy and compliance. Agent Workbench includes agentic AI with governance and security built in, featuring real-time logging, error tracing, and built-in guardrails. The platform includes mechanisms to prevent AI hallucinations and maintain explainability - the ability to understand how AI models arrive at decisions - addressing common enterprise concerns about AI reliability.
Can I deploy OutSystems applications on-premises?
Yes, OutSystems applications can run in the cloud, on-premises, or in hybrid environments. The platform provides flexibility for deployment based on organizational requirements. For on-premises deployment specifically, add-ons are available beyond the standard OutSystems Developer Cloud plan.
What is vendor lock-in with OutSystems?
OutSystems claims standard architecture with no lock-in, stating that if you stop your subscription you can retrieve the last version of generated source code (C#, HTML, CSS, JavaScript) and application data. However, in practice, detaching applications from the OutSystems runtime is very cumbersome and requires a large project. Moving tightly coupled applications becomes complex, and in many cases it's faster and cheaper to rebuild the application on a new open platform, meaning OutSystems is very much tied to its runtime.
How much does OutSystems cost per user?
OutSystems uses a custom pricing model that avoids per-developer seat charges. The Value Metric is based on Application Objects (AOs), which include screens, database tables, and APIs. The OutSystems Developer Cloud plan starts at $36,300 annually and includes three runtimes (dev, test, prod) and 100 internal users. The Free plan costs $0, while Standard and Enterprise plans have custom pricing based on usage, application complexity, number of end-users, and hosting environment. Annual billing typically saves 15-20%.
