Hey Solace Community! 
We want to make sure that you can learn all about Solace topics in a fun and easy way.With this in mind, we are thrilled to highlight an amazing open-source learning tool that lets you experience Solace event-driven messaging hands-on, in your browser, right now!
Introducing: Solace Topic Sandbox
Launch Sandbox → | GitHub →
The Problem
Learning pub/sub concepts can feel abstract:
- Reading about topic hierarchies doesn’t show you how they work in practice
- Understanding wildcards (
*and>) is easier when you can experiment - “How do I know if my subscription will match my published topics?”
- Theory is great, but hands-on experience is irreplaceable
For newcomers to event-driven architecture, bridging the gap between concepts and practice is often the biggest challenge.
The Solution
The Topic Sandbox is your interactive playground for learning Solace pub/sub patterns. It’s a safe, guided environment where you can connect, publish, subscribe, and experiment - all in your browser with real-time feedback.
The 5-Step Journey

Point the sandbox to any Solace Event Broker (cloud, local, or trial)

Add topic subscriptions to express what messages you’re interested in receiving
Construct Topics & Messages
Build topic strings and craft message payloads
Publish Messages
Send your first message and watch it flow through the system
Receive & Observe
See your messages arrive in real-time and understand how topic matching works
