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 ❤️

I've been working on more integrations for EventCatalog.
You can now connect your Azure Schema Registry to EventCatalog to sync your schemas with your docs.

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.

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 ❤️

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.

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

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. 🤩

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 👇

Soon you will be able to filter by domain, service, messages, teams, AsyncAPI and OpenAPI files.
Hopefully helping you find what you need, faster!

This is fun.
I'm working on raising events when certain things happen in folks architecture documentation.
Here a producer has changed a contract. EventCatalog knows the consumers, and notifies them of changes before they happen.
Hopefully can help you catch issues 🙏
