At Helper – Visual One-Time Job Scheduler for Developers

The at command schedules one-time jobs in Linux. Unlike cron, which runs tasks on a recurring schedule, at runs a command once at a specified time. At Helper is a developer-first visual tool for building, validating, and scheduling at jobs instantly — without memorizing time syntax.

Designed for developers, DevOps engineers, and system administrators, At Helper removes the cognitive overhead of at time specifications.

Why Use at Instead of Cron?

Cron is for recurring tasks. at is for one-time tasks.

Common scenarios where at shines:

  • Run a backup script once at a specific time
  • Schedule a report to be generated tomorrow morning
  • Delay a task by a specific interval (e.g., "in 30 minutes")
  • Schedule a maintenance window for a specific date
  • Run a one-time test or deployment at a precise moment

At Helper makes it easy to build these commands visually.

Flexible Time Specifications

at accepts a wide variety of time formats. At Helper supports them all:

  • Absolute time: 9:00 AM, 14:30, midnight, noon, teatime
  • Relative time: now + 5 minutes, now + 1 hour, now + 2 days
  • Date + time: 9:00 AM tomorrow, 9:00 AM next monday
  • Specific dates: Aug 1 2026, Jul 31, 2026-08-01

Just type or select a preset and the interpretation updates instantly.

One-Click Command Generation

At Helper generates a ready-to-use at command:

echo "/path/to/backup.sh" | at 9:00 AM tomorrow

Features:

  • Copy to clipboard

Preview Next Execution Time

Before scheduling a job, you should know exactly when it will run.
