draw.io vs Ilograph

draw.io is a free, open-source diagramming tool for creating visual layouts, from flow charts and mind maps to network, architecture, UML, BPMN and floor-plan diagrams. It supports real-time collaboration, and files can be opened and edited across platforms. Users can choose their own storage or save locally with the desktop app; draw.io says it cannot access users' data. No sign-up or credit card is required to start diagramming, and the desktop app is free forever. Diagrams can remain editable or be exported to SVG, PNG or PDF. Supported imports include draw.io, XML, Gliffy, VSDX, Lucidchart, PNG, SVG and JPEG. Integrations include Google, Microsoft, Atlassian, GitHub, VS Code, Notion and Chrome. Interactive diagrams can be embedded in documents, wikis or applications. The listed platforms are web, Windows, macOS, Linux, iOS and Android. Support is available through GitHub Discussions and Stack Overflow. The site says there is no Enterprise tier for SSO.

Ilograph creates interactive visual documentation for systems and the ways their components interact. Users can zoom between detailed and broad views, switch perspectives, and use sequence perspectives to show data, business and security flows. Its model-based diagrams-as-code approach adds structure and supports consistency and reuse. Diagrams can be navigated by keyboard and are designed for screen readers; environments include AWS, Azure, GCP and networking icons. Ilograph Desktop runs on Mac, Windows and Linux, and works with local files without internet access for offline or high-security environments. The Export API runs in an on-premises Docker container without external internet access and produces standalone HTML files. Its Confluence Cloud app stores diagrams in the Confluence instance and does not require an Ilograph account. The free plan includes unlimited public and private diagrams, unlimited diagram size and 14 days of history. Listed paid options include Pro at $18.00 per month billed yearly, Team at $30.00 per month billed monthly, and Desktop at $14.99 per month billed monthly.
