Sulu CMS is an open-source, Symfony-based content management system maintained by Zoorobot GmbH in Austria. Designed specifically for enterprise and corporate platforms, it provides structured multilingual content management, a drag-and-drop block editor, a built-in digital asset manager and a developer experience native to Symfony — without the compromises of adapting a blog CMS to enterprise needs.
What makes Sulu CMS the right foundation for serious enterprise web platforms.
Sulu is a Symfony application — not a framework that uses Symfony under the hood. Its routing, security, DI container and Console commands are all native Symfony. Any Symfony developer is immediately productive, and the CMS integrates seamlessly with your existing Symfony services, listeners and bundles.
Sulu's content model is built around locales from the ground up. Every page, snippet and media item can exist in multiple languages with independent content, URLs and metadata. Managing a 10-language corporate website is as straightforward as a single-language site — there's no afterthought i18n layer.
Sulu's page builder uses a block-based structure where editors choose from predefined content blocks (text, image, video, CTA, accordion, slider…) and arrange them freely per page. Blocks are defined by developers as Symfony FormTypes — fully typed and validated, giving editors flexibility without sacrificing structure.
A complete DAM is included: multi-folder organisation, automatic image resizing with focal point selection, WebP conversion, format-specific cropping configurations and usage tracking. No separate DAM tool needed for most enterprise requirements.
Sulu exposes a JSON:API and REST API for headless delivery. Content can be fetched by a Next.js or React frontend, a mobile app or a third-party consumer. The website document structure, media URLs and template assignments are all accessible via API.
Role-based access control at page, section, locale and action level. Define exactly which editors can publish which content in which language. Workflow states (draft, review, published) add an approval layer for organisations with compliance requirements.
Organisations that need a serious CMS for multilingual corporate platforms — company websites, product information portals, investor relations and multi-division enterprise sites with strict content governance.
Agencies and in-house teams already working with Symfony who want a CMS that integrates natively with their stack — sharing the same DI container, security model and deployment pipeline without bridging layers.
Organisations managing content in 5+ languages with multiple editorial teams and approval workflows. Sulu's locale-first architecture and granular permissions are designed precisely for this use case.

FAQ
Sulu CMS is dual-licensed. For non-commercial use (personal projects, non-profits, open-source projects) it is free. For commercial use, a one-time commercial licence is required — priced to be accessible for agencies and enterprises. As an official Sulu partner, we can advise on the correct licensing and handle the purchase as part of a project engagement.
WordPress excels for content publishing, blog-style sites and SMB websites where editorial ease and time-to-market matter most. Sulu is designed for enterprise platforms that require structured multilingual content, Symfony-native architecture and strict editorial workflows. WordPress's flexibility comes from plugins and custom development on top of a blog foundation; Sulu's structure comes from its Symfony core design. For a 10+ language corporate platform with compliance requirements, Sulu is the more appropriate choice.
Yes. Sulu has a JSON:API and REST API that make it fully headless-capable. The website structure, page content, media references and template assignments are all available via the API. We build Next.js frontends that consume Sulu's API — combining Sulu's structured content management with Next.js's SSR for fast, SEO-indexed pages.
Sulu CMS 2.x is the current major version. It requires PHP 8.1+ and Symfony 5.4/6.4. We always start new projects on the latest stable Sulu 2.x release and maintain compatibility with the LTS Symfony version for long-term support.
Yes. After project delivery, we provide editorial training covering page creation and editing, block management, media library usage, multilingual content management and publishing workflow. Training is available in person or remotely, tailored to your editors' technical level.
