14:02. Order #48213 leaves checkout.

A short film in five scrolls
The life of one Service Bus message.
Order #48213. From checkout, to the dead-letter queue at 3 AM, and back.
02 · Queued
It takes its place in line.
Thousands of orders, all waiting for a consumer. From the outside, ours looks like every other one.
03 · Failed
3:12 AM. Something dead-lettered.
The consumer rejects it. Again, and again. After the last delivery attempt, Service Bus gives up and moves it to the dead-letter queue.
04 · The old way
Blade. Spinner. Blade. Spinner.
The Azure Portal makes you click through blade after blade to peek one message. ServiceBusExplorer only runs on Windows. The CLI hands you a raw text dump.
05 · Fumiq
Find it. Fix it. Resubmit.
Open the Dead Letter tab, read the body as a proper tree, correct it and send it back to orders. It completes this time.
What you get
Five Service Bus tasks you will do every day.
01
Browse and peek
Browse every queue, topic, and subscription, and peek messages the moment you click.
02
Dead-letter repair
Sift through what dead-lettered, then resubmit the messages that deserve another run.
03
Message inspection
Read a message properly: the body as a syntax-highlighted tree, and every property beside it.
04
Send with a template
Fill a queue with realistic test data from one template, hundreds of messages at a time.
05
Command palette
Reach any action, or any entity in the namespace, without leaving the keyboard.

Move messages between environments

FAQ
Azure Service Bus explorer FAQ
How does the free trial work?
You get 30 days with every feature included, no credit card required. When the trial ends, buy a license and pick up right where you left off.
What happens when my year of updates ends?
Your app keeps working, forever. A license is a one-time purchase that never expires; the year of updates only determines which new versions you can install. Renew whenever you want another year of updates.
How do I activate my license?
After checkout, your license key arrives by email. Paste it into Fumiq and you're done. You can deactivate a machine at any time to move your license to another one.
How do seats work?
One seat is one developer. Personal includes a single seat, Team includes five, and Enterprise has no limit. Need a different size? Email hello@fumiq.app.
Do the prices include VAT?
Prices are shown excluding VAT. Checkout is handled by Polar, our merchant of record, which calculates the correct VAT or sales tax for your country and sends you an invoice by email.
Where are my connection strings stored?
Locally on your machine, and nowhere else. Fumiq talks to Azure Service Bus directly from your desktop; your connection strings and messages never pass through our servers.
Can I get a refund?
Yes. Every purchase comes with a 30-day money-back guarantee. Request a refund through your Polar order link or email hello@fumiq.app and we'll take care of it.
Why is Azure Portal slow for Service Bus?
The Azure Portal requires clicking through multiple blades and loading spinners to peek at a single message. Fumiq connects directly via AMQP, giving you instant access to all your queues, topics, and subscriptions in a native desktop app. Compare Fumiq and the portal.
Is there a cross-platform alternative to ServiceBusExplorer?
Yes. Fumiq is a native desktop app built with Rust and Tauri that runs on macOS, Windows, and Linux. The open-source ServiceBusExplorer is a capable tool, but it is a Windows-only .NET Framework app, so on a Mac or Linux machine you need a Windows VM to run it. Read the full comparison.
What's the difference between Fumiq and QueueExplorer?
QueueExplorer is a mature tool that also covers RabbitMQ, MSMQ and ActiveMQ, and it now runs on Windows, macOS and Linux. Its licenses start at $149 per computer, and custom columns need the $249 Professional edition. Fumiq focuses on Azure Service Bus, starts at €49 one-time, and includes JSONPath custom columns and a command palette in every license. Read the full comparison.
What does Fumiq cost?
Fumiq is a one-time purchase. The Personal license is €49 and the Team license (5 seats) is €199. Both include 1 year of updates. A free trial with full features is available.
