Your pager goes off.</p> <p>Azure Service Bus is showing thousands of dead-letter messages, but the Azure Portal only tells you a number. No message content. No failure reasons. No easy way to understand what went wrong or how to safely fix it.</p> <p>After experiencing this pain too many times, I decided to build <strong>ServiceHub</strong> — an open-source web-based forensic debugger for Azure Service Bus.</p> <h3> Try It Live — No Installation Needed </h3> <p>I’ve deployed a <strong>free hosted demo</strong> so you can test it instantly:</p> <p><strong><a href="https://app-servicehub-prod.azurewebsites.net/connect" rel="noopener noreferrer">→ Try ServiceHub Live Demo</a></strong></p> <p>Just paste your Service Bus connection string and click Connect.<br><br> It works safely with just <strong>Listen</strong> permission (read-only by default).</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F0mw6jzcadbsnxm5agnks.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F0mw6jzcadbsnxm5agnks.png" alt=" " width="800" height="500"></a></p> <h3> What ServiceHub Gives You </h3> <ul> <li> <strong>Full Message Visibility</strong> — Browse active queues, topics, and subscriptions with complete JSON body, system properties, custom headers, and syntax highlighting.</li> <li> <strong>Powerful DLQ Intelligence</strong> — Persistent history, auto-categorization of failures (Transient, MaxDelivery, Expired, etc.), forensic timeline, trend charts, and export to JSON/CSV.</li> <li> <strong>Auto-Replay Rules</strong> — Define smart rules once and automatically replay matching messages with live success statistics and rate limiting.</li> <li> <strong>Safe Batch Replay</strong> — Replay multiple messages safely with strong confirmation guards.</li> <li> <strong>AI-Powered Insights</strong> — Client-side pattern detection and anomaly flagging (no data leaves your browser).</li> <li> <strong>Testing Tools</strong> — Built-in Message Generator with realistic scenarios and anomaly injection.</li> </ul> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fejtaj2x6vx97krcpmif9.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fejtaj2x6vx97krcpmif9.png" alt=" " width="800" height="500"></a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F5lws8fuije7rvdkb8db1.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F5lws8fuije7rvdkb8db1.png" alt=" " width="800" height="500"></a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fbeh3h7kh03h1ulltiwz9.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fbeh3h7kh03h1ulltiwz9.png" alt=" " width="800" height="500"></a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Femlpq4c3my4maydjudk2.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Femlpq4c3my4maydjudk2.png" alt=" " width="800" height="500"></a></p> <p>All of this in a clean, modern web interface built with React 18 and .NET 10.</p> <h3> Run It Locally (Completely Free &amp; Open Source) </h3> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code> bash git clone https://github.com/debdevops/servicehub.git cd servicehub ./run.sh </code></pre> </div> azure devops opensource tooling
