bussinService Bus Explorer Alternatives
Bussin is a secure, browser-native alternative to traditional desktop messaging tools. It runs directly in your browser as a static client, establishing secure WebSockets connections directly to Azure. It conforms to your existing Entra ID permissions and role configurations without requiring intermediate servers.
Peek messages, inspect dead-letter reasons, and resubmit or purge messages instantly without downloading client executables.
Comparing the Main Options
When choosing a management client for Azure Service Bus, developers typically use one of three tools. Here is the core difference between each:
1. Azure Portal (Web Console)
The Core Difference: Built-in web utility. Good for basic queue metrics and configuration changes. However, it lacks advanced debugging features like custom message peeking, peek-lock settlements, search filtering, and environmental folder organization.
2. Service Bus Explorer (Paolo Salvatori)
The Core Difference: Classic Windows desktop client with full administrative control—create and delete entities, edit queue properties, manage authorization rules. Best suited for advanced broker administration tasks. However, the UI can be complex to navigate, it's Windows-only (requires Wine on macOS and Linux), and requires local installation with connection string configuration.
3. Bussin (Browser-Native)
The Core Difference: Clean web client that connects directly to Azure from your browser. Designed for quick access—get in, inspect or repair queues, and leave. It supports advanced workflows like inline message editing, custom JSON exports, and batch uploads, while remaining fully cross-platform, requiring no installation, and running entirely client-side.

Note: ~ denotes partial support (e.g. file exports are supported without interactive header filters in Paolo's tool, and Azure Portal resubmission is restricted to cloning from the DLQ without modification).
Bussin has no backend API, proxy server, or database access to your Service Bus. All actions conform to the user's active delegated Azure credentials. Your messages never leave your browser.
When to Use Which Tool
Azure Portal
Quick glance at queue depths, topic configurations, or subscription counts. Best for ops dashboards and configuration changes you make infrequently.
Service Bus Explorer (Paolo)
Deep administration tasks: creating and deleting entities, editing queue properties, managing authorization rules, or working with local emulators. Best when you need full broker control and don't mind the setup.
Bussin
Day-to-day message debugging: peeking at payloads, recovering dead-lettered messages, searching message bodies, resubmitting failed batches. Best when you need to get in, fix something, and get out—from any device, without any setup.
Frequently Asked Questions
Does Bussin replace the desktop Service Bus Explorer?
No. Paolo Salvatori's Service Bus Explorer covers advanced broker administration—entity management, authorization rules, and emulator support—that Bussin intentionally does not. Bussin focuses on the day-to-day messaging workflow: peeking, searching, settling, and recovering messages instantly from any browser.
How does Bussin connect without a backend?
Bussin establishes connection tunnels to the Azure Service Bus data plane over WebSockets (port 443). The protocol logic runs entirely client-side via WebAssembly in your browser, maintaining full security.
Does Bussin work with connection strings?
Yes! Bussin supports connecting directly using standard Azure Service Bus Connection Strings. This allows you to use the app in "Run without login" mode. It is particularly useful for connecting to external or partner Service Bus namespaces where you do not have Entra ID access. However, please note that the local Azure Service Bus Emulator is not supported directly because it lacks native WebSockets support (which browser-based applications require).
Can I use Bussin behind a corporate proxy or VPN?
Yes. Bussin communicates over standard WebSockets on port 443 (wss://), which passes through most corporate firewalls and proxies without additional configuration. No special firewall rules are needed beyond HTTPS access to your Service Bus namespace endpoints.
