Hello folks,

My name is Dave Boyne, I'm on a mission to help bring discoverability to event-driven architectures through open source.

If you love event-driven, distributed, serverless, then let's connect ❤️

Recently I have a few thoughts about EventStorming. Can we get more value from it's output?

I always loved the idea of taking an image of a EventStorm and generating an EventCatalog....

Here is what I found, with a working example, if anyone is interested

Can you get more value from your EventStorming workshops? I think you can....

So you finished an EventStorming session, you have 100s of post-it notes. What's next? In this blog post I explore an experiment of turning EventStorming into EventCatalog using MCP.

Thanks Andrew!

Just some thoughts on event-driven architecture, and why you should stop and think before you publish your first event....

Kicking off Monday with a new plugin for EventCatalog.

This will take your @graphql.org
schemas and turn them into documentation for your architecture, visualize it, assign owners and much more...

Hope it helps, anyone interested ❤️

My next project with EventCatalog is now live ❤️

Introducing EventCatalog Studio.

A design tool that focuses on architecture primitives, rather than boxes and lines.

It's early days, and I can't to learn from folks and make the project better for everyone.

Do we need another diagram tool? Maybe not… But I think we can do better

My thoughts on the pitfalls of diagram tools today, the value lost, and why we can do better.

Thanks Richard 👍

I'm considering a new talk next year.

Focused on my journey and lessons learnt building sustainable open source project.

Thoughts? Useful? Missing anything?

Love your feedback

Many folks building event-driven architectures, end up in some level of chaos.

I wrote up some quick thoughts here, and some resources and actions you can do today to help you.

Hope it can help!

I've been reflecting on event-driven architecture, problems in the eco-system and what needs to change.

Tldr; It's a mess, but we can do better 🚀

August brought a welcome change of pace as many took well-deserved summer breaks ❤️

While things were quieter overall, I stayed focused on two key areas: advancing EventCatalog Studio and strengthening the core platform.

Last summer break done👍

Time to refocus, and nail Q4 this year.

Plans

⭐️ Launch EventCatalog Studio
⭐️ Talks in conferences
⭐️ Reach 10k MMR through FOSS
⭐️ More integrations for EventCatalog
⭐️ xRegistry Support
⭐️ Make EventCatalog even better ❤️

Let's GO!

EventCatalog now supports webrtc channels ❤️

Focusing on architecture and messaging primitives allows us to build tools that can help many architecture types, patterns, and various different channels.

Hopefully it helps!

EventCatalog Studio - The visual designer for event-driven architectures

A smarter way to design and build event-driven systems.

Designing architectures?

Capture decisions as you design — and reference your diagrams right in your docs.

With EventCatalog Studio, just mention a database, event, or service, and it links automatically.

Small feature. Huge impact. 🤩

Seems ambitious, but fuck it.

I think we can do better, and I'm building something I believe can help ❤️

Export to Prompt 💡

1. Design some architecture
2. Export design to LLM prompt (into Mermaid)
3. Use Prompt in LLM.

Pretty fun!

Build a custom Astro integration that listens for EventCatalog Studio files (.ecstudio) and refreshes your docs ❤️

Hot reloading all the way!

David Boyne @boyney123.bsky.social · Aug 4

Thanks for the shout out @gornicki.bsky.social ❤️

@dcominottim.bsky.social let me know if you have any questions, or want to share your problems you face, always happy to speak to folks in this area. Just let me know! Happy to help you understand EventCatalog more too

Storing architecture decisions in Git is great—but we can do better.

I’m building a visual editor powered by Git:

✅ Own your data
✅ Version & diff
✅ Add Figma-style comments
✅ Run locally

Collaborate, document, even generate code.

Here’s a quick demo 👇

David Boyne @boyney123.bsky.social · Jul 31

Another month done ✔️

Here are a bunch of fixes, features we added to EventCatalog to help you all document, govern and discover your architecture.

Finding the right service, owner, or message in a distributed system shouldn’t be a pain.

I just rebuilt EventCatalog’s search to help orgs quickly filter & find the exact resources they need—faster onboarding, better collaboration, less guesswork.

I wanted to improve the search on EventCatalog.

Soon you will be able to filter by domain, service, messages, teams, AsyncAPI and OpenAPI files.

Hopefully helping you find what you need, faster!
