Whether you’re building multi-site enterprises or highly customised digital experiences, this analysis provides the clarity needed to make an informed decision.

What Are the Core Differences Between Umbraco and Kentico?

The main differences between Umbraco and Kentico come from their basic design philosophies: Umbraco is an open-source framework focused on developers, while Kentico is a complete enterprise platform for digital experiences.

Umbraco Features

Umbraco’s features focus on flexibility and customization. The platform provides a blank canvas where developers can build exactly what clients need without unnecessary extras. Its open-source nature grants complete access to the source code, allowing teams to modify core functionality, create custom workflows, and integrate any third-party service. The active community contributes thousands of free packages extending capabilities from SEO optimization to form builders.

Kentico Features

Kentico’s features prioritise completeness and readiness for large businesses. The platform comes with built-in tools for marketing automation, personalisation, e-commerce, analytics, and managing multiple sites. Developers can use pre-made components instead of creating them from scratch, which speeds up project timelines for organisations that need immediate functionality.

Licensing Models

The licensing models reflect these approaches distinctly:

• Umbraco: Core CMS remains free with optional paid Umbraco Cloud hosting services
• Kentico: Premium licensing based on deployment scale, features required, and support level

Extensibility

Extensibility differs significantly between the two platforms. Umbraco requires developers to integrate or build most advanced features through code, while Kentico offers configurable modules through its admin interface. This distinction directly impacts development time, technical requirements, and long-term maintenance strategies for large website projects.

How Does Each CMS Support Large Website Management?

Kentico excels at large website management through its unified dashboard that controls multiple sites from a single interface. Enterprise teams can oversee global websites, manage content across different regions, and maintain brand consistency without switching between platforms. The centralized approach streamlines workflows for organisations running dozens of sites simultaneously.

Multi-site support in Kentico includes:

• Shared content libraries across all properties
• Centralised user management and permissions
• Unified analytics and reporting dashboard
• Global template and design system management

Umbraco approaches scalability CMS requirements differently through its modular architecture. Developers build custom solutions that grow with project demands, adding functionality as needed rather than managing pre-built features. The platform handles high-traffic environments efficiently, with sites processing millions of monthly visitors without performance degradation.

Both platforms address multilingual content requirements effectively. Kentico provides built-in language management with version control for each locale, allowing content teams to publish region-specific variations simultaneously. Umbraco’s Language Variants feature enables developers to create multilingual structures with granular control over translation workflows, though implementation requires more initial configuration.

The architectural difference matters for development teams: Kentico delivers immediate multi-site capabilities suited for enterprises with established global operations, whilst Umbraco offers flexible foundations for custom-built large-scale solutions where specific requirements drive the architecture.

Which Platform Offers Better Developer Experience and Customisation?

Umbraco delivers a superior developer experience through its open-source nature and vibrant community support. Developers gain full access to the source code, enabling deep customisation without vendor restrictions. The platform’s clean, intuitive back-end interface reduces the learning curve whilst maintaining powerful extensibility through custom controllers, property editors, and content apps.

The open-source community surrounding Umbraco provides extensive documentation, forums, and ready-made packages that accelerate development. Developers can leverage thousands of community-built extensions or contribute their own solutions back to the ecosystem. This collaborative environment fosters innovation and problem-solving at scale.

Kentico offers robust customisation through its modular architecture and comprehensive API suite. The platform provides RESTful APIs, GraphQL endpoints, and .NET APIs that allow developers to build headless implementations or integrate with external systems seamlessly. Its component-based approach enables teams to extend functionality without compromising system stability.

Technical expertise requirements differ significantly between platforms:

• Umbraco demands stronger .NET development skills for implementing enterprise features, requiring developers to build or integrate third-party solutions for advanced functionality
• Kentico reduces development overhead with pre-built modules but requires understanding of its proprietary architecture and licensing constraints

When evaluating Umbraco vs Kentico: Which CMS Is Better for Developers Managing Large Websites?, the choice hinges on whether your team prioritises unlimited customisation freedom or accelerated deployment with enterprise-ready features.

How Do Umbraco and Kentico Address Security Needs for Enterprise Websites?

Kentico delivers enterprise-grade CMS security straight out of the box with minimal configuration required. The platform includes multi-factor authentication, role-based access control, and maintains ISO 27001 compliance alongside GDPR compliance features built directly into the system. Developers managing large enterprise websites benefit from pre-configured security protocols that meet international standards without additional development work.

Kentico’s built-in security features include:

• Multi-factor authentication for enhanced user verification
• Granular role-based access control for content and administrative functions
• Automated security updates and patches
• GDPR-compliant data management tools
• SSL certificate management
• Audit trails for compliance tracking

Umbraco takes a different approach to CMS security by providing a flexible foundation that developers can customize according to specific requirements. The core platform includes basic security features like user authentication and permission management, yet achieving enterprise-level security often requires integrating third-party tools or building custom solutions. This customizable security model gives developers complete control but demands more technical expertise and development time.

The security readiness gap becomes apparent when comparing deployment timelines. Kentico’s comprehensive security infrastructure allows developers to launch secure enterprise websites faster, whilst Umbraco projects require additional security hardening through custom development or third-party integrations. For organizations with strict compliance requirements, Kentico’s pre-certified security framework reduces audit complexity and accelerates compliance verification processes.

What Marketing and E-commerce Features Do They Provide Out-of-the-Box?

Kentico delivers comprehensive marketing automation and e-commerce integration as native components of its platform. The system includes built-in tools for email campaigns, A/B testing, contact management, and lead scoring without requiring external services. Its personalization features allow developers to create dynamic content based on visitor behaviour, demographics, and interaction history. The integrated e-commerce module handles product catalogues, shopping carts, payment processing, and order management through a single interface.

Umbraco takes a different approach by relying entirely on third-party integrations for marketing and commerce functionality. Developers must connect external platforms like HubSpot or Mailchimp for marketing automation, whilst e-commerce requires implementing solutions such as Ucommerce or Vendr. This modular strategy offers flexibility in choosing best-of-breed tools but demands additional configuration work.

The development workload differs significantly between platforms. Kentico’s unified approach means developers can implement marketing campaigns and online stores using familiar interfaces and documentation. Umbraco projects require:

• Evaluating and selecting appropriate third-party services
• Configuring API connections and data synchronization
• Maintaining multiple vendor relationships
• Managing updates across separate systems

Teams with limited resources benefit from Kentico’s ready-made solutions, whilst those seeking specific marketing tools or custom commerce workflows may prefer Umbraco’s integration flexibility.

How Should Developers Decide Which CMS Is Better for Their Large Website Projects?

Choosing the right CMS (Content Management System) for large website projects is crucial for successful development and long-term maintenance. Here are some key factors that developers should consider when making this decision:

1. Project Scope and Complexity

The scope and complexity of your project will greatly influence which CMS platform is best suited for your needs. If you’re managing multiple global sites with integrated e-commerce, marketing automation, and strict compliance requirements, Kentico’s unified ecosystem may be the ideal choice. On the other hand, if your project requires unique workflows, custom integrations, or specialized functionality, Umbraco’s open-source adaptability could be more beneficial.

2. Team Expertise Level

The level of expertise within your team also plays a significant role in selecting a CMS platform. Kentico’s user-friendly interface and built-in features make it easier for marketers and content editors to navigate without extensive technical knowledge. However, developers still have access to powerful APIs for customization when needed. In contrast, Umbraco requires strong .NET development skills to implement enterprise-grade features but offers greater flexibility through its developer-friendly architecture.

3. Budget Constraints

Budget limitations are another critical factor that can impact your decision between Kentico and Umbraco. Umbraco’s free core CMS reduces initial investment costs, making it an attractive option for organizations with skilled development teams who can build specific functionalities as required. On the other hand, Kentico has licensing fees associated with its comprehensive feature set which may lead to potential savings in development time and ongoing maintenance expenses due to pre-built solutions.

4. Built-in Versus Extensible Features

Finally, consider the balance between built-in features provided by each platform versus extensibility options available through custom development work. Teams who prefer immediate functionality without much additional coding effort may find themselves gravitating towards Kentico’s out-of-the-box capabilities while those valuing architectural control and long-term flexibility might lean towards Umbraco’s modular approach allowing them to tailor their system according to evolving business needs over time.
