# Supabase Queues

> Durable message queues with guaranteed delivery, powered by Postgres and pgmq.

Supabase Queues is a Postgres module that uses the pgmq extension to provide durable message queues with exactly-once delivery within a visibility window. Manage queues using SQL, the Supabase client libraries, or the Dashboard.

## Key Features

- **Real-time monitoring**: track and manage messages with built-in observability tools
- **Multiple access methods**: manage via SQL, PostgREST API (server-side or client-side), or Dashboard
- **Dashboard management**: create queues, send messages, and monitor processing in real time
- **100% open source**: built on pgmq, a trusted community-driven extension
