CronMaster

CronMaster is a self-hosted web interface for creating, viewing, and managing system cron jobs from a modern dashboard. It adds optional execution logging and live status updates, making cron-based automation easier to monitor and maintain.

Key Features

• Create, view, clone, and delete cron jobs, including comments/notes
• Human-friendly schedule presets and standard cron format support
• Optional job execution logging with stdout/stderr, exit codes, timestamps, and automatic cleanup
• Live updates via Server-Sent Events (SSE) for job status and long-running log streaming
• Built-in script management for bash scripts and reusable snippets
• System information dashboard (uptime, CPU, memory, network, and GPU when available)
• Authentication options: password protection and SSO via OpenID Connect (OIDC)
• REST API for cron management and system information, with optional API key auth

Use Cases

• Manage and audit maintenance tasks (backups, cleanup jobs, renewals) on servers and homelabs
• Centralize creation and monitoring of cron-driven automation with execution history
• Provide a safer operational workflow for teams that need visibility into scheduled jobs

Limitations and Considerations

• Docker-based setup commonly requires elevated privileges/root and direct host access to crontab files for full functionality
• Jobs without logging are executed synchronously with a timeout, which may not suit long-running tasks

CronMaster is a practical option when you want cron scheduling to be approachable, observable, and API-accessible. It fits well for administrators who rely on cron but want better visibility, easier edits, and optional SSO-protected access.
