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.

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.

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!

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.

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. 🤩

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

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 👇

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!

You can now embed Entity Maps in your docs — with filters to show only the entities you care about 👀
Perfect for making complex domains easier to understand.

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 🙏

Working on webhooks for EventCatalog.
You will be able to listen to events you are interested in, setup custom webhooks (e.g slack), and get notified when things are happening.
This example, shows a new team starting to consume an event you own with a message directly in your slack channel.
