Why I Chose to Bootstrap EventCatalog and What It Taught Me About Defining Success on Your Own Terms | A Bootstrapper's Diary What changes when you stop chasing VC milestones and start building for the life you actually want.

People have asked me in the past, why bootstrap? Why not raise money?

Here are some thoughts...

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!

Document events at the domain level - EventCatalog Domain-level messaging gives teams more flexibility in how they model their event-driven architectures

www.eventcatalog.dev/blog/domain-...

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

You can now embed IcePanel diagrams into EventCatalog

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....

not yet! but will take a look, thanks!

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!

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.

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.

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

Whats new in EventCatalog - September 2025 - EventCatalog EventCatalog updates for September 2025

Can’t believe it’s update time again 😅
Here’s what’s new in EventCatalog this September 🚀

✨ Studio – design + collaborate visually
🗄️ Data Stores – document + map usage
🔗 GraphQL Plugin – schemas → docs
📎 Attachments – link resources anywhere

Full update 👇
www.eventcatalog.dev/blog/eventca...

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!

Event-driven architecture is a shit show - It’s time to fix it Reflecting on event-driven architecture, it's problems and what needs to change.

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 🚀

Whats new in EventCatalog - August 2025 - EventCatalog EventCatalog updates for August 2025

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.

www.eventcatalog.dev/blog/eventca...

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!
