Ilograph review
A focused YAML-based tool for interactive architecture and cloud diagrams.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Ilograph is a model-based diagramming and system-documentation tool for technology professionals, engineers, and organizations. Its YAML source supports relation and sequence diagrams, automatic layouts, interactive zoom, focus controls, multiple perspectives, and guided walkthroughs. The product is available through a browser, desktop applications for macOS, Windows, and Linux, an API, and a Confluence Cloud app. It is most suitable for teams documenting system architecture, cloud environments, and technical relationships rather than creating a broad range of general-purpose diagram types.
The free plan includes unlimited public and private diagrams, unlimited diagram size, built-in AWS, Azure, GCP, and networking icons, and 14 days of diagram history. Pro costs $18 per user per month when billed annually or $22 per month when billed monthly, adding custom icons, unlimited diagram history, private viewers, shareable private links, and HTML export. Team costs $25 per editor per month when billed annually and adds team collaboration, a workspace dashboard, and unlimited viewers. Desktop costs $11.99 per user per month annually or $14.99 monthly, with offline editing, local files, custom icons, HTML export, and no internet access required.
Ilograph’s main distinction is the connection between structured YAML modeling and interactive presentation. Relation and sequence perspectives, cloud icon libraries, walkthroughs, password-protected sharing links, and self-contained HTML exports support architecture documentation that can be explored from different views. The free plan is practical for individual documentation and public or private diagrams, while paid options suit users who need custom visuals, longer history, private sharing, collaboration, or offline work. Choose Ilograph for architecture-focused diagrams-as-code and cloud views; choose another diagramming tool if you need a wider selection of diagram types.
