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.
