Left FAANG to build open source tools. No funding, bootstrapping my way forward. Building tools around event-driven architectures and distributed systems. 👨🏼💻 eventcatalog.dev ✍🏻 Learn EDA through my visuals http://eda-visuals.boyney.io
🆕 Introducing Architecture Graphs to EventCatalog This new view will show domains, systems, services and messages across your architecture, but in different views. The same information but different lenses on it. Hopefully useful! demo.eventcatalog.dev/visualiser/g...
A new version of the EventCatalog SDK is now out. The new Graph functions allow you to get your architecture documentation back as a graph. Architecture documentation isn't just static pages, it's a graph of information. EventCatalog let's you document your architecture this way.
I'm happy to announce custom pages and APIs for EventCatalog. Every team documents their architecture differently, and I want EventCatalog to flex to the way you work, not the other way around. www.eventcatalog.dev/blog/custom-...
I've been working on a new major version for EventCatalog Key updates ⭐️ Bigger vision for the project ⭐️ Support for systems (higher level components) ⭐️ Sync docs with code ⭐️ 20-60% faster catalogs ⭐️ Simpler plans and more features moved to free www.eventcatalog.dev/blog/eventca...
Been working on pulling real-time data into EventCatalog You can now create custom components, that can pull/sync information from anywhere. Here I pull data from my observability platform and render them into my docs All free and open source 🙌
You can now bring your c4 diagrams into EventCatalog. For those that are using C4 and building event-driven architectures, hopefully this can help. www.eventcatalog.dev/blog/c4-and-...
Playing with a new idea, a canvas that will let you import full or resources from OpenAPI/AsyncAPI into a diagraming tool for modelling, exploring and visualisation of architectures. Pretty fun so far 🤩
People have asked me in the past, why bootstrap? Why not raise money? Here are some thoughts... diary.boyney.io/notes/why-i-...

I've been playing with a slack bot integration with EventCatalog MCP server, which lets you ask questions about your architecture directly in slack. Ask about your domains, schemas, runtime metrics, ownership, on call folks... anything you want. Also bring your own model + tools Pretty fun!
I added a thing 🙌 You can now define messages at a domain level (not just service level) in EventCatalog. This let's you define domain events, and define how your domains interact with each other, and let your services be implementation details of that. Some users have been asking. Hope it helps
I added a small quality of life improvement to EventCatalog. You can now reference any resource using bracket syntax (e.g [[service|OrderService]]), to get this nice hover effect.
I added diagrams as a new resource type to EventCatalog. Bring any diagram you want to EventCatalog (Miro, IcePanel, Mermaid, PlantUML, etc) and assign them to domains, services and messages.... All diagrams can be versioned and compared too. Also you can copy diagrams to clipboards for LLMS.
What happens what you change the contract of your event? Who is going to be impacted? Who should be notified?... this can be answered with EventCatalog 🥹 Soon you will be able to change any schema (JSON, Avro, Proto, from any registry too) in your IDE and ask who will be impacted by this change....
Diagrams as a first class citizen to EventCatalog? Versioned? Comparison? I think there could be value here... Here is a quick demo of some mermaid and plantuml diagrams, versioned, assigned to a domain, and compared against each other 👇
Dark mode and themes coming soon to EventCatalog. I love how this is looking 👀, thanks to Claude Code it's saved me weeks of work so far!
I released a new major version of EventCatalog ❤️ Navigation improvements, caching improvements and general quality of life Hope it helps! www.eventcatalog.dev/blog/eventca...

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. www.eventcatalog.dev/blog/azure-s...
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 boyney123.substack.com/p/can-you-ge...
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 ❤️ www.eventcatalog.dev/integrations...
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. eventcatalog.studio

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! boyney123.substack.com/p/how-to-sto...
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 🚀 boyney123.substack.com/p/event-driv...
