In the pursuit of agility, have teams abandoned software design altogether? 🏗️ In his #dev2next keynote, @simonbrown.je explores why architectural thinking and upfront design still matter, helping teams avoid costly rework and move faster. 🔗 www.dev2next.com/speaker/8352... 🎟️ dev2next.com

@simonbrown.je and his C4 Model: *Draw context and containers, mostly leave the rest *The deeper levels go stale with every commit *What matters is getting everyone to agree what the words mean #GOTOpodcast episode with @suksr.bsky.social out now: gotopia.tech/podcast

Still relying on confusing architecture diagrams? 🏗️ Attend @simonbrown.je's hands-on workshop at #Dev2Next to learn why most diagrams fail, how to fix them, and how the C4 model can help you create clearer views of your software systems. 🔗 www.dev2next.com/schedule 🎟️ Get tickets: dev2next.com

Your architecture diagrams have unlabeled arrows, mystery boxes & 12 different shades of blue. Nobody knows what any of it means. @simonbrown.je wrote the book that helps & @suksr.bsky.social asked him everything you need to know about it. GOTO Book Club 👇 youtu.be/sfqHggWY5Ds?...

Half the industry is at level 1 of architecture diagram maturity. That means: nothing. Just vibes & boxes. @simonbrown.je — creator of the #C4Model — explains what levels 2 through 5 look like & how to get there. Spoiler: you need to stop diagramming & start modeling. youtu.be/FqTL-_tLf6I?...

The devs of today will become the ivory tower architects of tomorrow. "AI prompting + human code review" only works if the humans have technical knowledge, which will likely decline if humans are no longer writing code. Discuss. 😄

@simonbrown.je is coming to BCS Edinburgh Branch on Wednesday May 20th to talk about the latest developments in the C4 architectural diagramming system. Registration is free, but places are limited. edinburgh.bcs.org/events/2026/...

Locking your software architecture models away in proprietary tools? My original vision for Structurizr, separating workspace authoring from diagram rendering via an open JSON format, was to have an ecosystem of community tooling. ~30 tools now listed -> docs.structurizr.com/community

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/

Automated PNG/SVG exports from Structurizr -> www.patreon.com/posts/153245... (early access now available for Patreon members, free to read next week)

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...

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