What Ilograph does
Ilograph is a privately held, bootstrapped software company founded in 2016 by Billy Pilger and headquartered in Richmond, Virginia. It develops an interactive system architecture diagramming platform that uses a proprietary declarative language called IDL (Ilograph Diagram Language) to define resources, perspectives, relations, sequences, walkthroughs, and contexts as code with autocomplete and instant visual updates. The product differentiates through multi-perspective diagrams in which the same resources can be viewed through different lenses (security, deployment, data flow), zoomable interactive exploration, automatic layouts, and integrations with AWS Resource Explorer, GitHub, and Atlassian Confluence Cloud.
Ilograph distributes the platform through three deployment surfaces: a cloud-based web application (app.ilograph.com), a desktop application for offline or air-gapped use, and a standalone app on the Atlassian Confluence Cloud Marketplace. Revenue is generated via subscription: a free tier, Ilograph Pro at $18/month (annual) or $22/month (monthly) for individuals, and Team Workspaces / Team+ tiers for collaborative use, with Team+ adding SSO and API access. The company is privately funded, operates with 1-10 employees, and serves individual software engineers, cloud architects, and engineering teams at organizations that need to document complex distributed systems.
The go-to-market motion is product-led growth combined with content marketing: a public Architecture Center of reference diagrams, an active technical blog (multiple posts through 2025-2026), GitHub community discussions, and self-serve free-tier onboarding. Selected customers referenced on the website include KBRW and several anonymized enterprise users, with quoted end-users identifying as Principal Engineers, Cloud Architects, and Senior Software Engineers documenting distributed systems.

Ilograph product offering
Product offeringCore offering
Ilograph provides an interactive, multi-perspective system architecture diagramming platform that lets engineers and teams document complex distributed systems through diagrams-as-code. The platform is powered by its proprietary Ilograph Diagram Language (IDL), supports multi-perspective views (security, deployment, data flow), interactive zoom/focus, automatic layouts, guided walkthroughs, and sequence diagrams, and is delivered as a web app, an offline desktop application, and a Confluence Cloud integration.
Product overview
Ilograph is an interactive, multi-perspective system architecture diagramming platform. The product family consists of three core deployment options — Ilograph for Web (cloud browser-based), Ilograph for Desktop (offline desktop app), and Ilograph for Confluence Cloud (Atlassian Confluence integration) — all powered by the Ilograph Diagramming Language (IDL), a declarative YAML-based language for defining resources, perspectives, and relationships. The platform is available in tiers: a free individual tier, Ilograph Pro (adding custom icons, enhanced sharing, and diagram history at $18–22/month), and Ilograph Team Workspaces / Team+ (collaborative workspaces with SSO and API access). Ilograph also publishes the Ilograph Architecture Center, a library of reference architecture diagrams built with its own tool.

Products and services
- Ilograph for Web Ilograph for Web is the primary cloud-based offering, accessed in the browser at app.ilograph.com. It enables individual engineers and teams to create, edit, and share interactive multi-perspective system architecture diagrams using the IDL diagrams-as-code language with autocomplete, automatic layouts, zoom, walkthroughs, and context switching.
- Ilograph Desktop Ilograph Desktop is an offline desktop application for Windows, macOS, and Linux that delivers the full Ilograph diagramming experience in a local environment, for organizations and individuals who require total control of their diagrams or want to use Ilograph without internet access or behind firewalls.
- Ilograph for Confluence Cloud Ilograph for Confluence Cloud is a standalone Atlassian Confluence Cloud app that enables organizations to store, share, and collaborate on Ilograph diagrams entirely within a Confluence Cloud instance; it is distributed via the Atlassian Marketplace.
- Ilograph Team Workspaces Ilograph Team Workspaces is a collaborative cloud workspace platform for engineering teams to centrally store, share, and co-author interactive system architecture diagrams, with unlimited diagrams and viewers, custom icons, diagram history, password-protected links, and HTML export; offered in Team and Team+ tiers with SSO and full API access.

Ilograph competitors and assessment
Company assessmentDirect peers
- Mermaid: Mermaid is an open-source diagrams-as-code syntax natively rendered in GitHub, GitLab, and many documentation tools. It competes directly with Ilograph's diagrams-as-code value proposition for developers who prefer free, text-based authoring.
- PlantUML: PlantUML is a long-standing open-source tool for authoring UML and architecture diagrams from text definitions. It is a direct free alternative to Ilograph's IDL approach and is widely used in enterprise documentation workflows.
- Lucidchart: Lucidchart is the dominant SaaS diagramming platform serving enterprise teams for system architecture, flowcharts, and technical diagrams. It competes directly with Ilograph for the same software engineer and architect persona with overlapping feature sets.
- draw.io (diagrams.net): draw.io is a free, widely-used diagramming tool with deep integrations (Confluence, Jira, Google Drive). It is a direct substitute for Ilograph at lower price points and competes head-to-head on Ilograph's Confluence marketplace turf.
- Miro: Miro is a collaborative whiteboard platform widely used by engineering teams for architecture diagramming and system design sessions. It competes with Ilograph for the same technical buyer, though with a broader horizontal scope.
- Cloudcraft (by Datadog): Cloudcraft specializes in AWS and cloud architecture diagrams, including live infrastructure import. It directly competes with Ilograph's AWS Resource Explorer integration and AWS-focused use cases.
Broad incumbents
- Microsoft Visio: Microsoft Visio is the established enterprise diagramming incumbent bundled with Microsoft 365 E3/E5 plans. It competes broadly for the same architecture-documentation budget, though it lacks modern diagrams-as-code and interactive features.
Emerging players
- AWS Application Composer: AWS Application Composer is a free AWS-native tool for visually composing and documenting serverless applications. As a first-party hyperscaler tool with native infrastructure import, it competes directly with Ilograph's AWS workflow and is bundled at no incremental cost.
- Eraser: Eraser is a newer diagrams-as-code tool targeting engineering teams with AI-assisted diagram generation and version control integration. It overlaps with Ilograph's developer-focused positioning and is gaining traction in the same persona.
- Structurizr: Structurizr implements the C4 model for architecture-as-code with a DSL and visualization tooling. It overlaps with Ilograph's declarative IDL approach and is adopted by software architecture teams seeking lightweight documentation tooling.
