## What it is
rufus-scheduler is an in-process, in-memory job scheduler for Ruby supporting at, in, every, and cron scheduling styles using threads. It parses time strings via fugit and is intended to run inside a Ruby process rather than as a standalone cron replacement.

## Use cases
- run a job every 3 hours in a ruby app
- schedule cron jobs inside a rails process
- execute code after a delay in ruby
- run recurring background tasks without external cron
- schedule one-off tasks at a specific time in ruby

## When to choose
- you need lightweight in-process scheduling in a Ruby application
- you want cron-style or interval jobs without external infrastructure
- persistence of schedules across restarts is not required

## When to avoid
- you need schedules to persist across process restarts
- you need a distributed or multi-node job scheduler
- you want a standalone cron replacement or a dedicated job queue like Sidekiq

## Facets
- artifact type: library
- maturity: stable
- function: scheduling, workflow-automation
- domain: developer-tools, backend
- platform: ruby, cross-platform
- tags: cron, job-scheduler, in-process, threads, time-parsing, automation
