Cronmaster: Self-Hosted Cron Control with a Clean UI

Cronmaster is a self-hosted web UI for managing cron jobs and bash scripts on host machines. Built with Next.js, TypeScript, and Tailwind, it ships as a Docker container offering visual cron management, script editing with snippets, and system monitoring. The tool requires privileged container access and host mounts to edit crontabs in real-time, making it ideal for homelab operators and small server admins who prioritize convenience over strict security isolation. Installation is straightforward via Docker Compose, though the privilege model and host dependencies present tradeoffs for production environments.
