draw.io

draw.io, also known as diagrams.net, is a free and open-source diagramming application that has become the industry standard for creating technical and business diagrams in the browser. Trusted by millions of professionals across engineering, architecture, and operations, draw.io supports an extensive library of shapes and diagram types — from simple flowcharts to complex cloud infrastructure maps — with no account, subscription, or software installation required.

Common Use Cases

Engineering teams use draw.io to document system architectures, draw sequence diagrams, and create UML models that live directly in source repositories alongside code. Operations and DevOps teams produce network topology maps, infrastructure diagrams, and runbooks to keep documentation in sync with deployments. Business analysts model workflows with BPMN diagrams and create process flowcharts that stakeholders can review without specialized software. Security and compliance teams diagram threat models, data flows, and access control matrices to support audits and certifications.

Why deploy draw.io on Hostinger VPS

Cloud-hosted diagramming tools transmit diagram content to external servers — a risk that regulated industries, government organisations, and security-conscious enterprises cannot accept. Self-hosting draw.io on a Hostinger VPS ensures all diagram data, including sensitive architecture documents and infrastructure maps, remains exclusively within your infrastructure. The single-container, stateless design means zero database management overhead, instant startup, and straightforward upgrades by swapping the image tag. With Hostinger VPS you get dedicated resources, predictable performance, and the flexibility to co-locate draw.io alongside the systems it documents.
