8 Structurizr alternatives for architecture documentation
Structurizr's cloud service is at end of life and the tooling has consolidated into one binary. If that changes your plans, the questions are how much structure you want, where readers arrive, and what connects the model to reality.
Also searched as alternatives to Structurizr, Structurizr competitors, and Structurizr replacement.
What to look for when leaving Structurizr
How much structure you want
A model enforces one notation and rewards the teams who keep it. A canvas lets each diagram take the shape its subject needs.
Where readers arrive
Most readers want the overview, then one box. Check that the detail opens from the diagram rather than from a separate page.
Connecting the model to reality
A model describes intent. Look for a way to check it against the running estate, or it becomes a second thing to keep in sync.
The shortlist
Blueprintr
Diagram-first documentationA blueprint is a document that opens on a diagram. Every shape carries its own detail, and the blueprint publishes to one live URL. On Team, Continuum Cloud draws AWS and Azure from a read-only role. On Enterprise, Continuum Link attaches dated snapshots from monitoring and ITSM tools, and Continuum Local sweeps your on-premise network from inside it so Blueprintr can draw it.
- Draw it the way the subject needs. A C4 model renders boxes and lines. Vellum draws a network fabric, a data flow or a release pipeline with vendor icons, and a stratum on a container can hold the component diagram.
- Depth behind the shape. Structurizr attaches documentation to the workspace, a system or a container. A Blueprintr stratum sits on any shape and holds markdown, tables, code, files and tabs.
- Connected to what is running. Continuum Cloud scans AWS and Azure read-only on Team, and shows drift from Terraform state on AWS. Structurizr's model is maintained by hand or by code.
Free forever for unlimited blueprints. Premium is $10 a month, Team is $29 a seat a month, Enterprise is quoted.

How Blueprintr compares with Structurizr
Read from Structurizr’s own pages on 7 September 2026 and from Blueprintr’s pricing table. The plan label is the Blueprintr tier the capability lands on.
| Capability | Structurizr | Blueprintr |
|---|---|---|
| Diagrams and the detail behind them | ||
| Documentation behind every shapeCan a shape hold real content: markdown, tables, code, files? | Partly: Markdown or AsciiDoc documentation and decision records attach to the workspace, a software system or a container, not to every element. | Yes: A stratum on any shape: markdown, tables, code, files, links, tabs, even another diagram.Free |
| Hand-drawn diagrams with vendor iconsCan you draw freely, with real AWS, Azure, GCP and Kubernetes icons? | No: No drag-and-drop authoring. The browser editor changes layout only; content comes from the DSL. | Yes: Vellum, with vendor icon packs and your own SVGs. draw.io and Excalidraw are engines too.Free |
| Diagrams from textCan a diagram be written as code and kept in version control? | Yes: The Structurizr DSL, with a model rendered into many views and exported to PlantUML and Mermaid. | Partly: Mermaid tabs render from text and sit beside drawn tabs. Vellum diagrams are drawn, not coded.Free |
| A documentation siteLong-form docs with a nav tree, search and your own domain? | Partly: A static HTML site export of the workspace. | Yes: Folium: nested pages, search, your subdomain or custom domain, with live blueprints in the pages.Team and up |
| Present from the diagramCan the diagram itself be the slide deck? | No: Not offered. | Yes: Podium frames regions of a live canvas as slides and presents them in the browser.Premium and up |
| AI draftingCan AI draw a first draft, or convert a document you already wrote? | Partly: A free MCP server validates and inspects DSL and works with a server. No generation features. | Yes: Draft from a description or a document, and explain a shape. Every change is proposed, then confirmed by you.Free allowance, credits on paid plans |
| Keeping the diagram true | ||
| Draw AWS or Azure from a live accountWill it diagram what is actually running, read-only? | No: Not offered. Themes and icons for AWS, Azure and GCP. | Yes: Continuum Cloud takes a read-only role or a Reader app registration and scans the accounts or subscriptions and regions you choose, narrowed to a VPC, subnet or resource group.Team and up |
| Terraform drift on the diagramDoes it compare what you declared with what is running? | No: Not offered. | Yes: Point an AWS connection at your Terraform remote state. Drift from the declared infrastructure shows on the diagram.Team and up |
| Operational data on shapesCan a shape show the on-call, the open incidents or the uptime from the tools that report them? | No: Not offered. | Yes: Continuum Link attaches 39 connectors (PagerDuty, Datadog, ServiceNow, CloudWatch and more) as tabs on a stratum, each a timestamped snapshot an editor refreshes. On-premise systems such as SolarWinds, Zabbix and NetBox answer through Continuum Local, an agent inside your network that also sweeps it for Blueprintr to draw.Enterprise |
| Version history and diffsCan you see what changed since the last review, and restore? | Partly: The server keeps previous workspace versions, 30 by default, with revert. Diffs and merges are left to git. | Yes: Every publish is a snapshot. History diffs against any earlier version and restores it.Team and up |
| AI agents and an APICan Claude Code, Cursor or a script read and write your documentation? | Yes: A workspace API and an open-source MCP server. | Yes: A personal MCP server and a REST API, with scoped keys you mint yourself. |

Moving work from Structurizr
Export the views you want to keep as PNG or SVG and the documentation as the Markdown it already is. The Markdown pastes into strata and, on Team, into a folium. Redraw the views in Vellum, with a context diagram, container diagram and deployment view as tabs of one blueprint, and let a container's stratum open onto the diagram of its components. Decision records become pages in the folium.
Frequently asked
Why leave Structurizr?
Usually the end of the cloud service, the cost and effort of running the server, and the wish for diagrams with vendor icons and documentation behind every shape.
Which alternative is closest to Structurizr?
IcePanel, a C4 modelling tool that exports the Structurizr format. Blueprintr for a document with the detail behind each shape.
Can I keep the DSL?
Yes, and keep rendering it with the free commands. Export PNG or SVG for the tools on this list.
