## What it is
Asynq is a Go library for a distributed task queue backed by Redis, letting clients enqueue tasks that worker servers process concurrently. It includes scheduling, retries, priority queues, task deduplication, a web UI, and a CLI for inspecting and controlling queues.

## Use cases
- run background jobs in a Go web app
- schedule periodic tasks with cron-like behavior
- distribute work across multiple worker machines
- retry failed jobs with backoff
- process emails or reports asynchronously
- monitor queue metrics with Prometheus
- deduplicate identical tasks

## When to choose
- you're building in Go and need reliable async job processing
- you already run Redis and want a lightweight queue without extra infrastructure
- you need task retries, priorities, scheduling, and crash recovery
- you want horizontal scaling of workers with at-least-once delivery

## When to avoid
- you need a broker other than Redis (e.g. RabbitMQ, Kafka)
- you need exactly-once delivery guarantees
- your stack isn't Go and you'd rather use a language-native queue
- you need complex workflow orchestration beyond simple task aggregation
