Quantum is a cron-like job scheduler library for Elixir applications. It lets developers define recurring jobs using crontab syntax with timezone support, integrated into the OTP supervision tree.

Use cases

• run a task every minute in my Elixir app
• schedule nightly database backups
• execute periodic cleanup jobs with cron syntax
• run scheduled jobs in specific timezones
• replace system cron with in-app job scheduling

When to choose

• you need cron-style recurring jobs inside an Elixir/OTP application
• you want timezone-aware scheduling configured in code or config files
• you want jobs supervised as part of your application's supervision tree

When to avoid

• you need distributed job locking across multiple nodes out of the box
• you need a standalone scheduler outside an Elixir application
• you need complex workflow DAGs rather than simple cron schedules
