Ilograph creates interactive, zoomable system architecture diagrams as code. Free plan available; paid plans start at $11.99/month.
Ilograph is a diagrams-as-code tool purpose-built for documenting system architecture. Rather than manually dragging boxes and arrows, users define diagrams in a lightweight model, and Ilograph automatically generates a formatted, interactive layout.
Its signature feature is the ability to zoom between levels of abstraction within a single diagram — starting from a broad system overview and drilling into specific services, components, or sequence flows without needing separate, disconnected diagrams for each level of detail.
Ilograph diagrams are interactive and zoomable, letting viewers navigate a distributed system from a high-level view down to individual components and back. Sequence diagrams layered on top can highlight data, business, or security flows through the same architecture model.
Because diagrams are defined as code, changes update automatically with autocomplete support, avoiding the manual rearrangement common in drag-and-drop diagramming tools. Ilograph is available as a web app, a downloadable desktop application for offline use, and a Confluence Cloud plugin for embedding diagrams directly in documentation.
Ilograph offers a free plan with unlimited public and private diagrams in a personal cloud workspace and no diagram size limits, making it usable for individual architects without any cost.
Paid options include a Desktop plan at $11.99/month for offline access, a Team plan at $20 per user/month for shared team workspaces, and a Team+ plan at $30 per user/month with additional collaboration capabilities.
