Developer messaging toolkit

Inspect, send and receive messages without the boilerplate.

EventHub Explorer is a lightweight web UI for Azure Event Hubs, Azure Storage Queues, Azure Service Bus and RabbitMQ. Use production services or work fully offline with local emulators.

.NET 10.0MIT licensedDocker: dvlaskin/eventhubexplorer

Supported services

Azure Event Hubs

Namespace or Event Hub connections, plus eventhubs-emulator.

Azure Storage

Queues for messaging and Blob Storage for checkpoints, with Azurite.

Azure Service Bus

Queues and topics with namespace access and a local emulator.

RabbitMQ

AMQP/AMQPS queues and exchanges, including the management image.

Service	Real Azure / Broker	Emulator / Local
Azure Event Hubs	✓ Namespace and Event Hub connection strings	eventhubs-emulator
Azure Storage Queue	✓ `*.queue.core.windows.net`	Azurite
Azure Blob Storage	✓ Event Hubs checkpoint storage	Azurite (`UseDevelopmentStorage=true`)
Azure Service Bus	✓ Namespace-level Queue/Topic	Service Bus emulator
RabbitMQ	✓ `amqp://` / `amqps://`	`rabbitmq:management`

Features

All four systems share payload transformation, compression and batch sending. Entity types and receiving modes are service-specific.

Common operations

Operation	What it does
Override GUID / DateTime	Replaces detected values with freshly generated ones before sending.
Compress & encode	GZip + Base64 on send; automatic decode and decompression on receive.
Send messages	Send one, a batch, or a delayed batch with a configurable interval.
Auto-format JSON	Pretty-prints valid JSON payloads on receive.

Service-specific differences

Capability	Event Hubs	Storage Queues	Service Bus	RabbitMQ
Send to	Event Hub (partitioned stream)	Queue	Queue or Topic	Queue or Exchange (direct/fanout/topic)
Receive from	Event Hub, with/without checkpoints	Queue (polling)	Queue or Topic Subscription	Queue or Exchange-bound Queue
Checkpoint tracking	✓ Blob Storage	—	—	—

Event Hubs: $Default is used by default. Checkpoints require Blob Storage (Azurite locally or Azure Blob in production).

Requirements and installation

Docker is required for emulators or containerized runs. The .NET 10 SDK is required only for source builds. You need at least one service or broker to connect to.

Run locally from source

git clone https://github.com/dvlaskin/EventHubExplorer.git
cd EventHubExplorer
dotnet build
dotnet run --project src/WebUI/WebUI.csproj
# Open http://localhost:5235/

Run with Docker

docker pull dvlaskin/eventhubexplorer
docker run -d -p 5235:8080 --name eventhubexplorer dvlaskin/eventhubexplorer
# Open http://localhost:5235/

RabbitMQ

docker run -d --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:management
# UI: http://localhost:15672 (guest / guest)
amqp://guest:guest@localhost:5672
amqp://guest:guest@localhost:5672/myvhost
amqps://user:pass@hostname:5671/vhost

RabbitMQ: Queues and exchanges are declared automatically as durable. For an Exchange, provide both Routing Key and the Queue Name used to bind a receiving queue.
