    Zuzia

    Zuzia is a simple yet powerful tool for monitoring Linux servers and automating recurring system tasks. There’s no complex setup — just install a lightweight agent and manage everything from a clean, web-based dashboard. The core idea is straightforward: you can attach scheduled tasks to your servers, and Zuzia will run them at the right time, watch how they behave, and alert you if something goes wrong — whether the task fails, takes too long, or returns unexpected output. You can also run live shell commands from your browser, making it easy to check logs, restart services, or troubleshoot an issue — even from your phone, without needing SSH access. Zuzia also monitors your websites and SSL certificates, so you’ll know if a domain goes offline or a certificate is about to expire. It’s a tool made for developers, sysadmins, and small teams who want more control over their infrastructure without overcomplicating things.
