Cross-platform Desktop Solution

A native desktop application for exploring and managing Azure Service Bus resources

Connection Management

Add, edit, and delete named namespace connections with Connection String or Entra ID (Azure AD) authentication. Manage multiple connections side by side.

Resource Explorer

Browse queues, topics, and subscriptions in a collapsible tree with live active and dead-letter message counts shown inline.

Message Fetching & Operations

Peek (non-destructive) or Receive messages with PeekLock or ReceiveAndDelete. Complete, abandon, dead-letter, or resend with multi-select bulk actions.

Send Messages

Send messages with JSON (one-click formatting) or plain text body, full broker properties, and custom application key/value pairs.

Import & Export

Export messages to JSON for backup or replay, and import from JSON into any queue or topic. Jobs run in the background with status tracking.

Smart Search & Filtering

Filter by name, namespace:x, or has:dlq using special-phrase autocomplete. Combine phrases freely for powerful triage.

Custom Virtual Folders

Organize resources into virtual folders per namespace by workflow, team, or incident context - without changing anything in Azure.

Customizable Message Grid

Add, remove, and reorder columns via a right-click context menu. Create named views from any column layout, switch between them instantly, and persist them across sessions.

Emulator Support

Connect to the Azure Service Bus Emulator for local development. View resources, send messages, and fetch messages without a live Azure subscription.

MCP Server

Built-in Model Context Protocol server lets AI agents (Claude, GitHub Copilot, Cursor) query your namespaces directly. Enable in Settings — browse resources, peek messages, and get DLQ summaries from your AI tool.

Activity Log

Persistent panel at the bottom of the window captures connection and fetch events across all namespaces, giving you a running audit trail without leaving the app.
