# HZN Queue Console

> A desktop application for browsing, inspecting, filtering, and routing messages in RabbitMQ, ActiveMQ Classic, and ActiveMQ Artemis — built for developers.

HZN Queue Console is a native desktop tool (macOS, Windows, Linux) that gives developers a graphical interface for working with message brokers. Think of it like a database explorer, but for queues and messages. It requires no code to use and works directly over AMQP/Stomp/OpenWire connections.

## What it solves

- **Dead-letter queues (DLQ)**: Inspect failed messages, understand why they failed, and route them back to the source queue in a few clicks — without writing a consumer.
- **Message debugging**: Search across payload content, headers, correlation IDs, and routing keys to find exactly the message you care about.
- **Schema validation**: Import an AsyncAPI 2.x or 3.x specification and validate messages in real time — both when browsing and before publishing.
- **Undocumented systems** (beta): Record live broker traffic and generate an AsyncAPI spec from the messages that were actually seen — field types, enums, required fields and examples included.
- **Spec editing** (beta): Edit the spec visually or as YAML in the same editor, with a version history, diffs between versions, and PDF documentation export.
- **Message publishing**: Compose and send messages to any queue, with live schema validation and a side-by-side schema reference panel.
- **Table view**: Turn JSON payload fields into sortable table columns. Browse hundreds of messages at a glance.
- **Exchange topology**: Visualize exchanges, bindings, and queues as an interactive graph.

## Supported brokers

- RabbitMQ (AMQP 0-9-1)
- Apache ActiveMQ Classic (OpenWire / Stomp)
- Apache ActiveMQ Artemis (AMQP 1.0 / Stomp)

Multiple brokers and virtual hosts can be connected simultaneously.

## Key features

- Browse and paginate messages without consuming them
- Full-text search across payload and headers

- Bulk select and route messages to any destination queue
- Automatic x-death header cleanup on DLQ re-queue
- AsyncAPI 2.x and 3.x schema import and real-time validation
- Visual AsyncAPI spec editor with a two-way synced YAML source view (beta)
- Protocol bindings for server, channel, operation and message
- Traffic recording across every queue and topic on a server, without touching the real queues or their consumers (beta)
- One-click channel generation from recorded samples, with merge-and-conflict handling on re-record (beta)
- Spec version history with diffs, and any saved version can become the active one
- API documentation export as PDF
- JSON payload fields as table columns with named presets
- Export queue contents to JSON
- Real-time queue depth and consumer count monitoring
- Multi-broker, multi-vhost support in a single window
- Full keyboard navigation
- 14-day free trial, no credit card required

## Beta features

The AsyncAPI spec editor (visual editor and YAML source) and traffic recording with channel generation are in beta.

## Planned

- Git-backed spec versioning: spec history stored in a Git repository next to the code it describes, with saves as commits. On the roadmap, no release date.
