Congrats! 👏

Introducing the "C4 model and Structurizr DSL pattern catalog"! 📢

This pattern catalog presents a number of minimal examples of how to use the C4 model and the Structurizr DSL to model common patterns found in software architecture.

It worked well!

Define your software architecture model using the Structurizr DSL and be alerted when architecture drift is detected -> erode.dev/docs/models/...

(usual caveats apply: I haven't tried it, links/reposts from me are not recommendations, etc)

This morning's Structurizr + AI experiment ... you have a Structurizr server running, each team is pushing a workspace representing their view of the world. Use AI to generate a combined system landscape.

Tried this with Claude over the weekend - it worked first time, out of the box. 🚀

See docs.structurizr.com/ai/dsl-gener... for more details.

The new Structurizr MCP server (www.patreon.com/posts/152045...) makes it even easier for AI to generate valid Structurizr DSL now! 🚀

A free to read three part series of posts about why most AI generated architecture diagrams are terrible and how to fix them -> www.patreon.com/collection/2...

UI-driven vs "as code" | Structurizr Get more from Structurizr on Patreon

Following the Structurizr vNext announcement, I've had a few questions asking if the software architecture model can be modified via the UI, and if I have any plans to support a UI-driven approach to creating Structurizr workspaces.

See www.patreon.com/posts/151073... for the answer.

A Structurizr MCP server is available on GitHub! It provides an easy way to load workspaces from the local file system (JSON or DSL) and to load JSON workspaces from a self-hosted Structurizr server.

YOW! 2025 Software Architecture Speakers: Simon Brown with "The C4 Model - Beyond the Basics" and Andrew Harmel-Law with "Facilitating Software Architecture: Empowering Teams to Make Architectural Decisions"

🏗️ Let’s talk #SoftwareArchitecture!

@simonbrown.je & @andrewhl.bsky.social join #YOW25 to challenge how you think abt structure, scale, & collaboration in modern software systems.

📅 MEL 4-5 | BNE 8-9 | SYD 11-12 Dec

I'm doing a Reddit AMA in a couple of weeks ... more details at www.reddit.com/r/softwarear...

Thank you! 🙏

The new shapes are available in the next release, but you can build from source to use them now -> docs.structurizr.com/lite/building

C4 is notation independent, so they is no "new look" ... you can use whatever colours and shapes you like.

Those diagrams were created with Structurizr. 🙂

(source will released soon)

Thanks! Yes, there's a lot more content than the original book ... plus it has the new C4 model example diagrams.

Dive deep into what matters to you & your team in our 1-day #YOW25 masterclasses led by globally recognised tech experts, including @kevindubois.com @philippederyck.bsky.social @frankel.ch & @simonbrown.je

YOW! 2025 speaker Simon Brown The C4 Model: Beyond the Basics A smiling bespectacled man with slicked back grey hair

The #C4 model is a go-to for visualising software architecture, but how do you go beyond the basics?

@simonbrown.je will answer the most common C4 questions, from modelling shared code & microservices to tackling message-driven architectures.

#YOW25 MEL 4-5 | BNE 8-9 | SYD 11-12 Dec yowcon.com

Join @simonbrown.je in a 1-day hands-on #YOW25 masterclass on the #C4Model. Learn how to create meaningful diagrams that improve team communication and decision-making.
