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. Link: docs.structurizr.com/dsl/patterns/

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 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. Link: github.com/structurizr/...

Sneak peek! Join the C4 model Patreon if you want to be the first to hear about it... 🤔 www.patreon.com/c/c4model

Farewell "blue and grey boxes" ... the new example diagrams are now live on the C4 model website -> c4model.com

New C4 model examples are on the way! See patreon.com/posts/132584... for details.

I've updated the Structurizr DSL microservices example to take advantage of the new archetypes feature introduced a few weeks ago, which provides a richer and more concise DSL definition. The source can be found at github.com/structurizr/... if you're interested in taking a look.

Simon Brown @simonbrown.je · 05/04/2025

A timely post on Reddit to illustrate the point too... 😂

Simon Brown @simonbrown.je · 29/03/2025

Structurizr DSL archetypes are now available in the latest release of Lite, on-premises, CLI, and cloud -> docs.structurizr.com/dsl/archetypes

Show me an AI generated software architecture diagram and I'll tell you why it's bad. 😀 Seriously though ... if most humans are unable to adequately critique diagrams to determine whether they are good or bad, AI has no chance!

Simon Brown @simonbrown.je · 05/03/2025

Java and Spring fans ... join me shortly at @devnexus.bsky.social for my unique take on how to generate meaningful component diagrams from Java apps -> devnexus.com/presentation...

Simon Brown @simonbrown.je · 20/02/2025

The upcoming Structurizr DSL v4.0.0 release will now also support relationship archetypes. 🚀 Read more at www.patreon.com/posts/122686...

This week on the Structurizr Patreon ... "Enterprise usage - part 1" (free, signup required) describes what I see as a typical adoption pattern of the Structurizr tooling across an enterprise, and outlines some of the problems this can introduce. Link: www.patreon.com/posts/enterp...

Simon Brown @simonbrown.je · 18/02/2025

More work on Structurizr DSL archetypes today ... relationship archetypes are now supported too.

Simon Brown @simonbrown.je · 11/02/2025

Missed my software architecture workshop in Stockholm last week? I have a few more public workshops planned for the coming months in: - Malaga, Spain (J On The Beach) - Amsterdam, Netherlands (Trifork Academy) - Antwerp, Belgium (DDD Europe) Links on my website: simonbrown.je

Simon Brown @simonbrown.je · 10/02/2025

Join me at DubJUG in Dublin on Feb 27th for some insights into software architecture diagramming, and how to reverse-engineer useful diagrams from your Java apps. Register via ti.to/dublin-java-...

Simon Brown @simonbrown.je · 06/02/2025

#jfokus continues … for me anyway! 😀

Simon Brown @simonbrown.je · 05/02/2025

Really looking forward to presenting my new session this morning at #jfokus titled "Reverse-engineering architecture diagrams from your Java app" ... it's a summary of the work I did during the latter half of 2024 to make reverse-engineering component diagrams from Java apps more accessible.

Simon Brown @simonbrown.je · 08/01/2025

Happy new year! The first half of 2025 is shaping up nicely. Here's a list of the public events I'll be speaking at -> simonbrown.je#2025 (more TBC)

Early start to the week … heading to Belfast for a C4 model workshop tomorrow.

Simon Brown @simonbrown.je · 30/11/2024

Just queued up on the Structurizr Patreon for publication next week ... how to model a product where the implementation can vary based upon the customer's environment.

Simon Brown @simonbrown.je · 28/11/2024

Porto Tech Hub conference was a lot of fun - thanks for having me! The slides from my talk can be found at static.simonbrown.je/pth2024-c4.pdf

A big thanks to the fabulous team at Trifork Amsterdam for a very fun couple of days … a sold out software architecture workshop and a lovely “Trifork and friends” dinner. 🙏😊

Simon Brown @simonbrown.je · 20/11/2024

This (just added to the C4 website/book) needs to go into my "C4 misconceptions" talk...

Things that are not usually software systems in the C4 model include product domains, bounded contexts, business capabilities, feature teams, tribes, or squads.

Simon Brown @simonbrown.je · 19/11/2024

An early (and very windy) start for JER-LHR-AMS. Not a private jet, just first onboard. 😀

Simon Brown @simonbrown.je · 16/11/2024

The lovely folks at Gearset in Belfast are running a free event next month ... see gearset.com/dev-connect-... for details.
