Fumiq vs the Azure portal Service Bus Explorer
Based on Microsoft's Service Bus Explorer documentation as of October 2026.
The Service Bus Explorer in the Azure portal is free, needs no install, and covers the basics: peek, receive, send, and re-send from the dead-letter queue. For a quick look it is often enough. It gets slow when you work with messages all day, and a few things it cannot do at all.

Dead-letter resend in the portal
Re-sending a dead-lettered message from the portal sends a copy and leaves the original in the dead-letter queue, so you clean it up by hand, one message at a time. Fumiq sends the copy and completes the dead-lettered original in one step, for a whole selection at once. Either way, Service Bus cannot send to a single subscription, so a message resent from a subscription's dead-letter queue goes to its topic and reaches every subscription whose filter matches. More in the dead-letter queue guide.
When the portal is enough
If you check a queue now and then, cannot install software, or only need to peek a handful of messages, the portal does the job and costs nothing extra. Fumiq is for people who live in their queues: on-call engineers, integration developers and platform teams.
