## What it is
Apalis is a type-safe, extensible background processing library for Rust for building durable, distributed job and task processing systems. It supports multiple backends (Postgres, Redis, SQLite), Tower-based middleware, cron scheduling, sequential and DAG workflows, and a web UI for monitoring.

## Use cases
- run background jobs in a rust web app
- schedule cron tasks in rust
- process email sending queues asynchronously
- build distributed task workers backed by postgres or redis
- orchestrate multi-step DAG workflows
- monitor and retry failed background tasks

## When to choose
- you need type-safe, macro-free background job processing in Rust
- you want durable queues on Postgres, Redis, or SQLite
- you need retries, rate limiting, and graceful shutdown out of the box
- you want Tower middleware compatibility and observability via tracing

## When to avoid
- you need a language-agnostic message broker consumed by non-Rust services
- you need enterprise features like encryption at rest or batch processing without a paid plan
- you want a zero-dependency in-process job runner without a database backend

## Facets
- artifact type: library
- maturity: active
- function: message-queue, scheduling, workflow-automation, middleware, monitoring
- domain: backend, developer-tools, microservices
- platform: rust, windows, self-hosted
- tags: background-jobs, job-queue, task-processing, postgres, redis, sqlite, cron, tower, worker, dag-workflows, web-ui, automation, linux, macos, docker
