How much does Structurizr cost?

Structurizr offers a freemium model. Structurizr Lite is free and self-hosted. The hosted cloud service requires a paid subscription, with pricing based on workspace count and users.

Does Structurizr have a free plan?

Yes, Structurizr Lite is free and runs locally via Docker or CLI. It includes most features but lacks cloud storage, collaboration, and advanced security. The cloud service is paid.

What are the best alternatives to Structurizr?

Alternatives include IcePanel (drag-and-drop), Archi (ArchiMate), and PlantUML (diagrams as code). Unlike Structurizr, these may not be C4-specific or support ADRs.

Who is Structurizr best for?

Software architects, DevOps teams, and developers who want to model architecture as code using the C4 model. It’s ideal for version-controlled documentation and CI/CD integration.

Who should avoid Structurizr?

Teams wanting drag-and-drop UI diagramming, quick whiteboard sketches, or real-time collaboration should avoid it. Non-technical stakeholders may find the DSL steep.

Does Structurizr support PlantUML or Mermaid?

Yes, Structurizr has plugins for PlantUML, Mermaid, and WebSequenceDiagrams, allowing export to these formats via scripting.

Is Structurizr easy to set up?

Setup varies: Structurizr Lite is simple via Docker or CLI. The DIY approach requires learning the DSL and C4 model, which has a learning curve for new users.

Can I use Structurizr with AWS or Azure?

Yes, Structurizr includes prebuilt themes for AWS, Azure, and GCP to style diagrams. It integrates with CI/CD pipelines and version control systems.

What are the key limitations of Structurizr?

It requires committing to the C4 model and DSL. No real-time collaborative editing. The cloud service is paid; free self-hosted Lite lacks collaboration and security features.

Is Structurizr good for teams documenting microservices?

Yes, Structurizr is excellent for microservices architectures as it supports container and component diagrams, versioning, and ADRs to track design decisions.

Can I export diagrams from Structurizr to PNG or SVG?

Yes, Structurizr can export diagrams to PNG, SVG, and static site formats. The cloud service also supports interactive diagram viewing.

Does Structurizr support Architecture Decision Records?

Yes, Structurizr has built-in support for Architecture Decision Records (ADRs), allowing you to document and link decisions to your architecture model.

Structurizr is the definitive tool for teams committed to the C4 model and treating architecture as code. Its DSL is powerful but has a learning curve, and the lack of a drag-and-drop UI may frustrate casual users. The open-source local tooling is a strong foundation, but advanced features require self-hosting or the paid cloud service.

About Structurizr

FreemiumIntermediateAPI availableWeb · Desktop · CLI · API · Plugin

Structurizr is a "models as code" tool designed for the C4 model, enabling you to create multiple software architecture diagrams from a single textual model written in Structurizr DSL. It is intended for software architects and developers who want to version-control their architecture and keep it in sync with code. Structurizr provides a rich interactive diagram viewer and editor, supports automatic layout, and can export diagrams to various formats including PlantUML, Mermaid, WebSequenceDiagrams, and static site generators. It also offers features like architecture decision records (ADRs), scripting, and plugins. The tool comes in several forms: a local command-line interface (CLI), a lightweight server (Structurizr Lite), an on-premises server, and a hosted cloud service. It integrates with CI/CD pipelines via API and supports workspaces, versioning, branches, and role-based access control. What sets Structurizr apart is its focus on the C4 model (context, containers, components, code) and the "diagrams as code" paradigm, allowing teams to treat architecture as a first-class artifact in their software development lifecycle. As the reference implementation created by the C4 model author, it offers the best compliance with the standard.

Behind the Verdict

Structurizr is not for everyone, but if you're sold on the C4 model, it's hard to beat. The DSL is precise and version-control friendly, making architecture reviewable in pull requests. The recent v2026.05.22 release keeps the binaries up to date, but no groundbreaking changes were announced. We'd reach for this when the team already uses C4 or is willing to adopt it. The local CLI and Structurizr Lite are free, while the cloud service adds collaboration features like workspace branches and review workflows for a fee. Where it bites: the learning curve for DSL can slow initial adoption. Non-technical stakeholders may struggle without a diagramming UI. Also, real-time collaborative editing isn't supported, and the cloud service is paid. Compared to alternatives like PlantUML or Mermaid, Structurizr offers deeper C4 model compliance and richer interactive diagrams. But if you just need quick sketches, drag-and-drop tools like draw.io are faster. In practice, Structurizr shines in regulated environments where architecture documentation must be auditable and versioned. If that's your use case, it's a strong choice.
