Frequently asked questions
What is DiagramDeck?
DiagramDeck is a cloud-based diagramming platform that provides hosted draw.io diagrams with real-time collaboration features. It allows teams to create flowcharts, cloud architecture diagrams (AWS, GCP, Azure), UML diagrams, ER diagrams, network diagrams, and org charts in a shared workspace. DiagramDeck is fully compatible with draw.io files, meaning you can import and export .drawio files seamlessly. It is designed as a modern alternative to Lucidchart, Microsoft Visio, and self-hosted draw.io, combining the open draw.io ecosystem with enterprise-grade team collaboration, managed hosting, and security features like SOC 2 and GDPR compliance.
How is DiagramDeck different from Lucidchart?
DiagramDeck differentiates itself from Lucidchart in three key ways. First, it offers full draw.io file compatibility — you can import, edit, and export .drawio files, which Lucidchart does not support. Second, DiagramDeck provides managed draw.io hosting, giving teams the familiar draw.io editor experience without self-hosting infrastructure. Third, DiagramDeck offers a generous free plan with no trial limitations, while Lucidchart requires a paid subscription after a short trial period. Both platforms offer real-time collaboration, cloud architecture shapes, and enterprise security, but DiagramDeck bridges the gap between draw.io's open ecosystem and Lucidchart's polished collaboration features.
Is DiagramDeck free?
Yes, DiagramDeck offers a free plan that lets you create diagrams, collaborate in real-time, and export to PNG, SVG, and PDF. The free plan includes access to all diagram types including flowcharts, cloud architecture diagrams, UML, and ER diagrams. For teams that need advanced features, DiagramDeck offers a Pro plan at €15 per month and an Enterprise plan at €55 per month with SSO, admin controls, and dedicated support. No credit card is required to start.
Does DiagramDeck support draw.io files?
Yes, DiagramDeck is fully compatible with draw.io files. You can import existing .drawio files directly into DiagramDeck and continue editing them with all shapes, styles, and connections preserved. You can also export diagrams back to .drawio format at any time. This makes DiagramDeck the ideal choice for teams currently using self-hosted draw.io who want to upgrade to managed cloud hosting with real-time collaboration features — without losing any existing work or changing their workflow.
What types of diagrams can I create with DiagramDeck?
DiagramDeck supports a wide range of diagram types for technical and business teams. You can create cloud architecture diagrams for AWS, GCP, and Azure with official provider shapes, flowcharts and process flow diagrams, UML class and sequence diagrams, entity-relationship (ER) diagrams for database design, network topology diagrams, organizational charts, wireframes, and mind maps. The drag-and-drop editor includes thousands of shapes across categories, and you can customize every aspect of your diagrams with advanced styling options including custom themes, gradients, and rich text formatting.
